The Talons of Weng-Chiang (TV story)

The Talons of Weng-Chiang was the sixth and final serial of season 14 of Doctor Who. It is often considered one of the most popular serials. Fan-favourite characters Henry Gordon Jago and George Litefoot made their first and only televised appearance, but later they were given their own audio series, Jago & Litefoot.

It was also the final story to be directed by David Maloney. Soon after completing this story, Maloney was offered the producership of the BBC's new science fiction series Blake's 7.

Synopsis
The Fourth Doctor brings Leela to Victorian London to see how her ancestors lived but is rapidly drawn into a fiendish plot involving Chinese Tongs, disappearing women, an Oriental stage magician with uncanny powers, a murderous ventriloquist's dummy, and giant rats in the sewers.

A dozen women are missing, believed dead. The murder of a cab driver married to one of the missing women causes the Doctor and Leela to encounter a police pathologist, Professor Litefoot, and a member of the Chinese tong which carried out the murder. The latter leads the Doctor to become suspicious of Li H'sen Chang, a police interpreter, who is also a stage magician appearing twice-nightly at the Palace Theatre.

Chang is secretly the henchman of Magnus Greel, a 51st century war criminal masquerading as the Chinese god Weng Chiang. Greel fled through time to escape his enemies and is searching for his lost time cabinet, which by chance has fallen into the possession of Litefoot. Theatre owner Henry Gordon Jago assists the Doctor in his investigation of Chang's vanishing lady illusion, by which the women are being kidnapped — and ultimately murdered to feed Weng Chiang.

The plot casts Weng Chiang in the role of the phantom of the opera, haunting the cellars of the Palace Theatre, his bodily decay fended off by extracting the life energy of the victims Chang brings him. The Doctor must track him down, and find the Time Cabinet first, because any further use of it will cause a catastrophe. It uses zygma energy, and the zygma experiments lead only to disaster.

Part 1
Chinese magician Li H'sen Chang entertains a Victorian music-hall audience with his dummy Mr Sin. After the show, as Chang talks with theatre manager Jago, Joseph Buller arrives and accuses Chang of being involved in his wife's disappearance. Buller threatens to call the police, and as he leaves, Chang and Mr Sin exchange significant glances — across the room from each other...

The Fourth Doctor and Leela arrive in period costume, in which Leela is feeling very uncomfortable. When she questions why she has to dress so oddly, the Doctor jokes that she'll scare the horses if she wore her animal skins. They head for the theatre, as the Doctor plans to show her how her ancestors enjoyed themselves. Meanwhile, as Buller walks home, he is confronted by Mr Sin, holding a knife. The Doctor and Leela hear a scream and investigate. They find several Chinese men carrying the body of Buller. After a scuffle, most of the men run off at the sound of police whistles, leaving one behind. The police take the Doctor, Leela, and the Chinese man to the station on suspicion of causing an affray.

At the theatre, while Chang performs, Jago notices blood running down the dummy's arm. At the police station, the police sergeant, Kyle, questions the Doctor and Leela. The police find a body, this time in the river, which has been badly mauled. Chang arrives at the police station to help question the Chinese man as an interpreter. He surreptitiously gives the man a poison pill, and the man takes it and dies. The Doctor notices the man was marked as a member of the Tong of the Black Scorpion, a Chinese criminal organisation that follows the god Weng-Chiang. The Doctor takes charge of the situation, giving Kyle orders to have the body removed to the mortuary for examination; he suspects scorpion venom as the cause of death. At the theatre, Jago goes into Chang's dressing room to investigate the dummy. He is joined by his doorman, Casey, and they head for the cellar.

The Doctor and Leela go to the mortuary and meet Professor Litefoot. The Doctor and Litefoot deduce that Buller (whose body had been dumped in the river) was attacked by an apparently giant rodent but was already dead from a knife wound to the heart. The Professor is startled by Leela's knowledge of knife fighting, and the Doctor hastily invents a cover story of her being raised by savages in the Amazon. The Doctor recalls that the Tong's patron Weng-Chiang is the god of abundance and growth — he could make things grow larger. The Doctor leaves and is attacked by a Chinese Tong thug, but the man falls dead when Leela attacks him with a janis thorn (angering the Doctor). The two climb down into the sewers to investigate and find a giant rat coming at them...

Part 2
The Doctor and Leela climb back up the ladder, escaping the giant rat after throwing their oil lantern at it.

In the theatre's cellar, Jago and Casey find a lady's glove, monogrammed with the letters "E.B.", but Chang arrives and hypnotises Jago into forgetting what he has seen. When Jago leaves, Chang descends into a hidden sub-basement and kneels to a figure dressed in black... the sinister Weng-Chiang. The latter needs to find his lost Time Cabinet in order to repair his damaged physiology, but meanwhile requires the life essence of humans to survive — hence Chang is kidnapping women off the streets. Chang now warns him about the Doctor, whose mind he cannot read with the powers Weng-Chiang has given him.

The Doctor and Leela rejoin Litefoot at the mortuary, where PC Quick gives them information about Buller's last known movements; he was last seen heading to the Palace Theatre, making "'orrible threats". Litefoot invites Leela and the Doctor to dinner, but on the way the Doctor departs for the Palace Theatre to investigate, planning to rejoin them later. He meets Jago (who initially thinks him a performer trying to audition as a supporting act in the show), de-hypnotising him to enable him to remember what Chang had made him forget: as a result, Jago realises that the initials "EB" on the glove he has found stand for "Emma Buller" — the missing wife of the cabbie who had confronted Chang earlier. They head for the cellar, encounter a giant spider, and go through a trapdoor that leads toward the river Fleet. They see a "ghost", and Jago faints; but the Doctor recognises the apparition as a hologram and realises someone is using it to scare off intruders.

Litefoot and Leela are having dinner — a strange experience for him, given Leela's lack of table manners. Nearby, Chang and Weng-Chiang (quartering the city in a horse-drawn carriage) discover that the Time Cabinet is in Litefoot's house; Chang and Mr Sin prepare to steal it, sending Weng-Chiang back to the Palace Theatre. Litefoot notices someone lurking in his garden and, leaving Leela in his dining room, fetches a gun and investigates.

Jago recovers from his faint, and he and the Doctor chase the returning Weng-Chiang through the theatre. Weng-Chiang hits Jago from behind and nearly kills the Doctor, before getting away. Litefoot, finding nothing outside, returns to the house. Leela, waiting for him, hears him open the front door, then hears the sound of a groan and of a body falling. She opens the passage door to find the dwarfish Mr Sin menacing her with a knife...

Part 3
Leela hurls her own knife at Mr Sin, which lodges in its neck, but otherwise does not affect it. Finding she is unable to harm Sin, who plainly intends to murder her, she leaps through a closed plate glass window to escape. The Doctor ducks at the sound of breaking glass, just as Chang shoots at him from his place of concealment in the garden. Chang and Sin flee in a carriage, but Leela races after it and stows away on the back. The Doctor tends to Litefoot's injuries, and they discuss what the thieves might have been after — including Litefoot's valuable antique Chinese cabinet.

At daybreak, the Doctor and Litefoot are mapping out the sewers and the course of the River Fleet, which now runs wholly underground. The Doctor proposes an expedition by boat to locate the confluence of the Thames and the Fleet. He brings along a blunderbus (which he terms an elephant gun), into the muzzle of which he loads all manner of ammunition. A worried Litefoot warns him that, if he fires it, it will probably explode in his face, but the Doctor tells him that's unthinkable — it was made in Birmingham!

In the early dawn, Chang hypnotises a young woman in the deserted streets and brings her to his dressing room at the Palace Theatre, watched by Leela, who is still following him. When Chang leaves to find a second victim, Leela switches places with the first girl. Chang then brings the disguised Leela, and a young cleaning woman he has taken from the theatre itself, before Weng-Chiang, who grumbles about how wiry they are.

The Doctor enters the sewers alone, leaving Litefoot waiting in the boat. In the theatre's cellar, Weng-Chiang puts the cleaning woman in a distillation chamber and turns it on. Leela attacks him and turns off the machine, but the woman has already been aged to death. Leela escapes into the sewers, but Weng-Chiang closes the barred gate and summons the giant rats by sounding a dinner-gong; when they don't find their usual food waiting, they will comb the sewers for it...

Two Chinese laundrymen arrive at Litefoot's house and exchange one laundry basket for another. Meanwhile, at the theatre, the hypnotised young woman whom Leela replaced awakens, initially remembering nothing, but then she recalls Chang attacking her and flees. Jago tells Casey he is working on the mystery of the missing women with someone high up in Scotland Yard (the Doctor).

In the cellars below, Weng-Chiang accuses Chang of failing to obey the order to kill the Doctor and dismisses him for his failure.

In the sewers, Leela flees from a giant rat. Elsewhere in the sewers, the Doctor hears noises and prepares to fire. He sees Leela race into view, being attacked by the giant rat and screaming in agony...

Part 4
The Doctor fires the ancient blunderbus, causing a cacophonous explosion, which miraculously kills the rat without also killing Leela. The latter is more bothered by her failure to kill Weng-Chiang. They hear another rat coming and depart hurriedly, as the gun will take at least half an hour to reload. Returning to Litefoot's house, Leela describes the fate of Weng-Chiang's latest victim. Litefoot fetches a change of clothing for Leela, who is still wearing the disguise she adopted at the theatre, sending her off to change with the help of his housekeeper, Mrs Hudson, while the Doctor and Litefoot discuss the key of Litefoot's mysterious Chinese cabinet. A well-dressed Leela returns and is delighted to learn they are to attend that evening's performance at the Palace theatre.

At the theatre, in the meantime, Chang overhears Jago and Casey discussing the imminent return of a Scotland Yard investigator, who he deduces to be the Doctor. He readies a gun, then informs Weng-Chiang that to appease his wrath he will kill the Doctor.

That evening, the Doctor and Leela attend the first show at the Palace Theatre, where they are met by Jago. During his act, Chang performs a card trick with the Doctor's assistance, which involves firing a "magic bullet" through a selected card without hitting the others in the pack. Chang successfully completes this, without succumbing to the evident temptation to shoot the Doctor instead, then invites the Doctor onto the stage to participate in his "Cabinet of Death" trick (the vanishing lady illusion). Meanwhile, Weng-Chiang, lurking beneath the stage, encounters Casey preparing the Cabinet illusion and murders him.

Two Chinamen arrive at Litefoot's house, killing the policeman on guard. The diminutive Mr Sin is already inside the house, having arrived earlier concealed in the laundry basket, and lets them in.

The Doctor escapes from the Cabinet of Death by the simple expedient of using the concealed door in its back, as Chang rotates the cabinet to show that it supposedly has no rear door, much to the amusement of the audience. Chang cracks a joke, in an attempt to recover the situation: "The bird has flown. One of us is yellow!" His Chinese assistant, Lee, steps inside the cabinet instead, and Chang continues the trick, which involves running a number of swords through the box.

Climbing down a concealed ladder beneath the stage to escape being run-through by the swords, Lee comes face-to-face with Weng-Chiang and faints with shock. "So... the great magician!", Weng-Chiang muses to himself, looking upwards. On-stage, Chang is handed the final sword by the Doctor and concludes the trick, but when he and the Doctor open the cabinet doors, Casey's lifeless body is revealed inside, which falls out onto the stage. Jago orders the curtain brought down quickly, while Chang, who is as surprised as everyone else, flees — as Jago frantically cancels the night's performance and offers refunds.

The Doctor and Leela locate Chang in Weng-Chiang's cellar hideout, which is now abandoned, with all the equipment removed. Chang explains how his "god" appeared in China many years earlier, ill from his journey through time, and that they have been looking for the Time Cabinet — taken by the Emperor's soldiers — ever since.

Jago arrives, distracting the Doctor and Leela, enabling Chang to flee into the sewers. Leela then finds the clothing of the missing women in the cellar; and, as Jago realises that his star turn was responsible for all the disappearances, a scream is heard. The Doctor explains darkly: "You'll need to find a new top of the bill..." The Doctor blames the Time Cabinet for Weng-Chiang's deformed condition, which he explains is worsening every time he absorbs life-energy. He agrees with how Leela tries to see this explanation — as a waterbag with a hole in it: every time he puts more water in the bag, the hole just gets bigger. As the others leave, Jago starts planning how to make money out of the hideout: "See the lair of the phantom — bob a nob!"

Shortly thereafter, the Doctor and Leela return to Litefoot's house, only to find the body of the murdered policeman outside, and the unconscious Litefoot inside; with Weng-Chiang and Mr Sin driving furiously away, taking the Time Cabinet with them, as Mr Sin laughs uproariously...

Part 5
Treating a bruised Litefoot, the Doctor deduces that Mr Sin must have been hiding in the laundry basket. He now reveals that Sin is actually the Peking Homunculus, a device which is partly organic (containing the cerebral cortex of a pig), partly electronic, and from the future (about the year 5,000 A.D.). It delights in carnage and was responsible for the murder of the Commissioner of the Icelandic Alliance, an event which almost triggered a World War. At about that time, a scientist named Findicus discovered the Nexus Particle, upon which he based the Sigma experimentss, a crude and dangerous way to travel through time. The Doctor realises that Weng-Chiang's Time Cabinet could incorporate a sigma beam at full stretch, and, if so, its use by someone who doesn't properly understand Sigma technology could destroy London. Taking Leela with him, he sets out to track down Weng-Chiang's new hideout, using their one clue: the address of the Chinese laundry, on the label of the laundry basket Sin came in.

Weng-Chiang still lacks the key of the Time Cabinet, which is in a carpetbag he accidentally left behind at the Palace Theatre. He now forces one of his followers, Lee, to commit suicide as punishment for not bringing it.

Jago has found the carpetbag in question, and, learning that the Doctor and Litefoot have been seen together, he takes it to Litefoot's house. They leave the bag and a note for the Doctor there, and go on to the theatre together, to watch for anyone who might be sent to search for the bag.

The Doctor and Leela arrive at the Chinese laundry and find Chang, dying from injuries sustained from the attack by the giant rat. He is heavily drugged by opium to dull the pain and wants to revenge himself on Weng-Chiang. He dies after giving the Doctor two strange clues: a touch on his shoe, and a message to "beware the eyes of the dragon". The Doctor grumbles that he's left them a Chinese puzzle.

Jago and Litefoot follow a group of Chinese to the Tong's new headquarters, where they are spotted from a window by Weng-Chiang. They are captured, and Weng-Chiang threatens to kill Jago if Litefoot does not tell him where the key to the Time Cabinet is. After Litefoot reveals it's at his house, he and Jago are put into a locked room along with two young women who have been hypnotised — Weng-Chiang's next meal. The Doctor and Leela arrive at Litefoot's house and find the note and the carpetbag containing the key — a crystalline roundel the Doctor describes as a trionic lattice. Leela wants to help Jago and Litefoot, but there is no clue as to where Weng-Chiang now is, so the Doctor thinks it better to wait for Weng-Chiang's men to come to the house, since they will be looking for the key. They search for weapons to set up an ambush.

Jago and Litefoot find a dumb-waiter in the wall of the room in which they have been imprisoned, and use it to escape into the throne room — where they are recaptured.

As Leela stands before a curtained window in Litefoot's dining room, practising with an improvised weapon — one of Litefoot's golf clubs — Weng-Chiang sneaks out from behind the curtain and chloroforms her. As she struggles, she pulls off his mask, revealing a hideously deformed face...

Part 6
As the Doctor returns with a pile of possible weapons, Weng-Chiang confronts him with the unconscious Leela. Weng-Chiang threatens to let Mr Sin kill Leela if he will not hand over the Cabinet's key, but the Doctor makes a deal with him. They will all go to the House of the Dragon. Weng-Chiang will release Jago and Litefoot, and then the Doctor will give him the key. They all go, leaving Leela behind at the Doctor's insistence, but she recovers and follows them.

At the Tong headquarters, the Doctor realises that Chang's shoe clue referred to the tongue of his shoe — the "Tong". Mr Sin secretly climbs into the head of a large dragon statue, where there is are laser controls inside. The Doctor and Weng-Chiang talk, with Weng-Chiang revealing his real name — Magnus Greel. The Doctor knows of him: he is from the 51st century and is a war criminal responsible for over one hundred thousand deaths — the "Butcher of Brisbane". Jago and Litefoot are brought out to the Doctor, who now also wants the two young girls freed. Greel, angered, orders Mr Sin to fire on them; laser beams come from the dragon's eyes to hit the Doctor, who realises the second clue from Chang — "beware the eyes of the dragon" — before passing out. The three men are put back into the locked room. When the Doctor has recovered, he sets a trap. After bringing the girls out of their hypnotic trance, he makes a gas bomb that blasts some of the Tong men. They all escape, with the girls running out of the building to safety. Leela has made it to the House of the Dragon but is captured and put into Greel's distillation machine. He turns it on, but the Doctor has grabbed a hatchet and flings it at the machine, disabling it. Incensed, Greel orders Mr Sin to kill them, and they take cover behind a bench as Mr Sin fires the laser at everyone, including the Tong. The Doctor tries to convince Greel to not use the Time Cabinet, knowing it will cause a massive implosion that will kill them all. Leela finds a gun near a dead Tong and disables the dragon's laser eyes after a few bad shots ("I've never fired one of these before!" she protests when Litefoot complains). Greel pulls a gun on Leela, but the Doctor throws him into his own distillation machine; he undergoes a cellular collapse and crumples into dust. Mr Sin exits the dragon and jumps onto Leela, but the Doctor stops him by yanking his computer core out of him. He then smashes the lattice, bringing the Zygma experiment to a end.

Jago and Litefoot accompany Leela and the Doctor to the TARDIS. Litefoot attempts to explain tea to Leela, but it only baffles her more. The Doctor and Leela say farewell to Jago and Litefoot as they enter the TARDIS. Astonished by its dematerialisation, Litefoot thinks its impossible, and Jago says that maybe even the great Li H'sen Chang would have appreciated the stunt...

Story notes

 * This story had working titles of The Foe from the Future and The Talons of Greel.
 * "Weng-Chiang" was originally going to be the Master, following on from The Deadly Assassin, but producer Philip Hinchcliffe had this changed as he didn't want to have the Master revealed as the secret villain twice in the same season. Alan Barnes has pointed out several clues in the story that still point to the original plan: the time cabinet (read "TARDIS") and Greel referring to Leela as "the first morsel to feed my regeneration". (DWM 475)
 * Some associations and influences have been noted for The Talons of Weng-Chiang (in the main, derived from well known movies, the era of Philip Hinchcliffe and Robert Holmes in Doctor Who being strongly influenced by concepts and monsters made famous by Hollywood). Among the influences in this serial are:
 * Magnus Greel's lair beneath the theatre, his deformed face, the mask he uses to hide it, and the climactic scene in which the mask is torn off to reveal his true face, all derive from 's novel  and its film adaptations.
 * Throughout the serial, the Doctor wears an Inverness cape and a deerstalker hat, which were the characteristic apparel of film versions of Arthur Conan Doyle's detective Sherlock Holmes. The name of Litefoot's housekeeper, Mrs Hudson, is borrowed from Sherlock Holmes's housekeeper at 221B Baker Street. The giant rat echoes a famous untold Sherlock Holmes tale: in the Conan Doyle story, Holmes mentions "the giant rat of Sumatra, a story for which the world is not yet prepared." Tom Baker says at one point, "Elementary, my dear Litefoot", parodying "Elementary, my dear Watson", a line widely associated with Holmes in the Hollywood adaptations of the Conan Doyle stories (although never actually spoken by him in the Conan Doyle canon). Moreover, Litefoot's role, as a police surgeon, is an almost-exact parallel of Dr Watson in the Conan Doyle stories, who was an Army surgeon, but had retired into a civilian medical practice: Litefoot is playing Dr Watson to Tom Baker's Sherlock Holmes. Also, throughout the serial, Victorian London is generally depicted as shrouded in fog: another characteristic element of the Hollywood adaptations of the Holmes stories. (This production's in-joke is: Robert Holmes meets Sherlock Holmes.)
 * Coincidentally, Tom Baker would play Holmes in a BBC TV adaptation of The Hound of the Baskervilles shortly after leaving Doctor Who.
 * The giant rat is reminiscent of animals grown to enormous size in the H. G. Wells science fiction novel.
 * Li H'sen Chang is reminiscent of Fu Manchu, the Chinese villain of a series of novels by (and the many films based on those novels).


 * This is the only story of the Fourth Doctor's era in which he does not wear his famous long scarf at any point (due to the running joke of the Doctor wearing a traditional Sherlock Holmes costume throughout the story).
 * This is one of two stories (the other being Horror of Fang Rock) in which Leela does not wear her "savage" costume. As the character was originally inspired by Eliza Doolittle, as depicted in the 1962 film My Fair Lady, it was decided to try to move her away from her Sevateem trappings, hence in this serial she was put into period dress.
 * The conductor of the Palace Theatre's orchestra is played by incidental music composer Dudley Simpson. Because Simpson was not a member of the actors' union Equity, he had to be paid a special fee.
 * By the time Robert Holmes began writing The Talons of Greel, it had become apparent that Hinchcliffe, and possibly Holmes too, would be leaving the show at the end of the season. Hinchcliffe therefore decided to throw caution to the wind, and spent record amounts on the production: utilising many different locations as well as agreeing to expensive night-shoots.
 * During production of The Talons of Greel Hinchcliffe's successor, Graham Williams, gradually took over the reins, his first concern being the character of Leela. Williams approached Louise Jameson with an offer for the actress to stay on for Season Fifteen. This was a decision at odds with a promise Hinchcliffe had made to Tom Baker that Leela would be written out of the show at the conclusion of Season Fourteen. Baker was of the opinion that the character was too violent for the show, and would have preferred to carry on without a companion at all. Jameson was initially reluctant to continue, mainly because of her frosty relationship with Baker, but also due to the brown contact lenses she was compelled to wear. When Williams offered to relinquish the need for contact lenses, Jameson agreed to sign a contract for the whole of season fifteen.
 * The lenses were removed at the end of Horror of Fang Rock, when Leela's eye pigmentation is changed from brown to blue (Jameson's natural eye colour) when she watches the Rutan mothership explode. (TV: Horror of Fang Rock)
 * This is not the only historically-based story of the Fourth Doctor's era (e.g. The Masque of Mandragora, Horror of Fang Rock). After the two-pronged approach of "historicals" set in the past and science fiction stories set in the future was abandoned (when Patrick Troughton was the Doctor, after The Highlanders) fewer historical stories were made. This is one of those few. Jon Pertwee, whose stories were frequently set in the present, had only one story set in real history: The Time Warrior. Peter Davison had The Visitation and a pair of two-parters: Black Orchid and The King's Demons. Colin Baker had one in The Mark of the Rani and Sylvester McCoy had several including Delta and the Bannermen, Remembrance of the Daleks and The Curse of Fenric.
 * The later comic book story The Time Machination revealed that the Doctor and Leela's arrival in London occurred immediately after the departure of the Tenth Doctor, who had just shared an adventure with H. G. Wells against the Torchwood Institute; according to the comic, Wells witnesses their arrival.
 * This story has garnered controversy in recent years for its stereotypical portrayals of the Chinese. Aside from character actor John Bennett, an Englishman, playing the role of Chang in yellowface (a practice where yellow makeup and prosthetics are applied to make an individual appear Asian), the story has been criticised for portraying its Chinese characters as either "coolies" (locally sourced labourers, often Chinese) or tong members. Most of this controversy is in the US and Canada, where racial stereotyping and yellowface fell into disfavour many years earlier than it did in the UK. Indeed, TV Ontario refused to air it after consulting with local Chinese-Canadian groups, and multiple stations in the US and Canada also declined to air it.
 * The audio story The Butcher of Brisbane serves as both a prequel and a sequel to this story.

Production errors

 * When the Doctor and Leela emerge from the TARDIS at the beginning of part one, they leave the door partly ajar. They walk away to the poster of Chang, then hear the attack on Buller and run past the TARDIS again. The TARDIS door has closed.
 * When the Doctor and Leela first encounter the members of the Tong dragging the body of Buller away in part one, there are four of them. But after their fight, and when they disappear, there are now five of them.
 * The script refers to Henry Gordon Jago as proprietor of the Palace Theatre, and the Doctor refers to attending a performance, as though the venue was a playhouse. Yet we do not see a play performed. The scenes set within clearly depict what was known as music-hall entertainment. A series of turns (performers) present their respective acts (sketches), introduced by a Master of Ceremonies: Little Tich; Six-gun Sadie and her Wild West troupe; Lee H'sen Chang, Master of Illusion; etc (based on Robert Holmes's familiarity with the then-current BBC TV series The Good Old Days - a recreation of Victorian Music Hall). The production team - including the director - don't seem to appreciate the distinction between what later became known as Variety (in the USA, vaudeville) and the legitimate stage of William Shakespeare, Oscar Wilde, or George Bernard Shaw.
 * There are modern power points, covered with masking tape, on the walls of Litefoot's lab.
 * A 1970s newspaper (the headline concerns Denis Healey) can be seen in Litefoot's laundry basket in part three.
 * When the Doctor enters the opium den in part five, the lip-sync on his line "Weng-Chiang will show his hand again" is several seconds out.
 * A boom mike shadow is visible on the curtains near the stage in the final fight in part six.
 * When the Doctor smashes the crystal key on the ground in part six, the deactivated Mr Sin flinches.
 * When the laser beam from the dragon hits a vase in front of Leela, a crewmember's hand from behind the curtains can be seen giving it a helping push over.
 * When Leela grabs the revolver from a dead coolie, one of the supposedly "dead" extras can be seen moving his leg a couple of times.
 * The axe in between the eyes of the dragon is missing in the shot in which the Doctor tells Jago and Litefoot he'll buy them muffins.
 * When Leela tells the Doctor, "Professor Litefoot has been explaining to me about tea", a boom microphone briefly enters the shot in the top left corner.

Continuity

 * The Doctor confronts the aftermath of this story's events in PROSE: The Shadow of Weng-Chiang.
 * The Doctor revisits Litefoot in PROSE: The Bodysnatchers.
 * The events surrounding Magnus Greel and his time experiments are shown in some detail in PROSE: Emotional Chemistry.
 * The Doctor says that he was last in China 400 years ago. He was certainly there in 1289, some 600 years earlier, in his first incarnation (TV: Marco Polo). The 400 years might reference roughly 400 years experienced by the Doctor in his personal timeline, or perhaps an unrecorded visit in the 15th century.
 * The adventures of Henry Gordon Jago and George Litefoot continue in PROSE: A Victorian Interlude, AUDIO: The Mahogany Murderers and the subsequent Jago & Litefoot audio series.
 * The events of this story take place immediately after those of COMIC: The Time Machination featuring the Tenth Doctor. The Fourth Doctor and Leela's arrival in the opening scene is reproduced in the comic book.
 * Later, during his fifth incarnation, the Doctor and his companions Nyssa, Tegan Jovanka and Turlough would encounter a younger version of Magnus Greel in Peking, China and Reykjavik, Iceland in the early 51st century. As they were unaware of Greel's ultimate fate, Nyssa and Turlough plotted to overthrow him. Although it was not part of their initial plan, Nyssa became engaged to him whilst Turlough posed as their secretary (AUDIO: The Butcher of Brisbane).
 * The Doctor mentions to Greel that he was with the Filipino Army when it marched on Reykjavik in the 51st century. He doesn't reveal that on that occasion (AUDIO: The Butcher of Brisbane) he was provided with information by his fifth incarnation, which enabled him to avert World War VI.
 * Greel tells the Doctor that he encountered a Time Agent in the 51st century. Unbeknownst to the Doctor, Greel is referring to the Doctor' future self (AUDIO: The Butcher of Brisbane).
 * Greel's mind was later reconstituted by Guinevere Godiva in 1968 by using a Venusian crystal. He took possession of Detective Inspector Dave Sacker to continue living. Jago and Litefoot discovered Greel's plan to return. Greel died when Ellie Higson stood in the distillation chamber and overloaded the power of his time cabinet. (AUDIO: The Final Act)
 * Jago would later describe the day that he met the Doctor and Leela as the last day that his life was normal. (AUDIO: The Night of 1000 Stars)
 * Patsy would later assist Jago and Litefoot in several of their investigations. (AUDIO: Jago & Litefoot & Patsy, Higson & Quick)
 * Sherlock Holmes would later investigate Mr Sin, terming it The Affair of the Walking Ventriloquist's Dummy. However, he was unable to solve the mystery. (PROSE: All-Consuming Fire)
 * The Doctor is showing Leela the culture of her ancestors. (TV: The Face of Evil)
 * The Doctor tells Leela that she would have loved the Battle of Agincourt. During his first incarnation, the Doctor, Susan Foreman, Ian Chesterton and Barbara Wright encountered Henry V shortly before the battle. (PROSE: The Reign Makers) Ashildr fought at Agincourt on the English side. (TV: The Woman Who Lived)
 * Six-Gun Sadie previously performed at Ford's Theatre in Washington DC in 1865. (AUDIO: Assassin in the Limelight) She was still performing in 1935. (AUDIO: Enemy Aliens)
 * Mrs Hudson still had Leela's dress in the wardrobe in the 1890s. (AUDIO: Dead Men's Tales)

Notes:
 * The video had some slight edits to remove the use of during the fight scene between the Doctor and the Tong of the Black Scorpion in part one, as these were at the time classed as illegal weapons in the UK and couldn't be shown on-screen. This ruling has since been relaxed, and the sequence appears intact on the DVD release.
 * Although it has been popularly believed that the scene in part five of the Doctor gaining access to the opium den by poking the key out of the lock and pulling it under the door on a piece of paper was edited out of the video release, this is not the case; the sequence was retained intact. (The British Board of Film Classification had originally wanted this scene removed to avoid showing a children's hero breaking and entering. However, BBC Video decided to retain the whole sequence — explaining to the BBFC that the trick rarely worked in real life.)
 * The BBC Video release was at one point only available in Australia.
