The Chase (TV story)

The Chase was the eighth story of Season 2 of Doctor Who. As well as featuring the first use of time travel by the Daleks, it also featured the departures of original companions Ian Chesterton and Barbara Wright, played by William Russell and Jacqueline Hill respectively, and the first appearance of new companion Steven Taylor, portrayed by Peter Purves.

It saw the same story style as Nation's The Keys of Marinus, with the TARDIS crew being in different locations nearly every episode. A similar style would later be used in The Daleks' Master Plan and The Infinite Quest. The Chase also saw fictional characters making appearances; while they are robotic duplicates in this story, similar appearances would occur throughout the programme's history. It also saw the program's take on the mystery of the Mary Celeste, a story that would be contradicted by other in-universe media. Later, the story Carnival of Monsters would feature a mysterious ship, albeit a fictional one.

Synopsis
The travellers are forced to flee in the TARDIS when they learn from the Time-Space Visualiser taken from the Moroks' museum that Daleks equipped with their own time machine are on their trail with orders to exterminate them.

The chase begins on the desert planet Aridius and takes in a number of stopping-off points including a spooky haunted house which is actually a futuristic fun-fair attraction.

Eventually both time machines arrive on the jungle planet Mechanus, where the Daleks try to infiltrate and kill the Doctor's party using a robotic double of him. The travellers are taken prisoner by the Mechonoids - robots sent some fifty years earlier to prepare landing sites for human colonists who never arrived - and meet Steven Taylor, a stranded astronaut who has been the Mechonoids' captive for the past two years.

The Daleks and the Mechonoids engage in a fierce battle which ends in their mutual destruction, and the Doctor's party seizes this opportunity to escape. The Doctor reluctantly helps Ian and Barbara to use the Daleks' time machine to return home.

The Executioners (1)
As the Dalek's place the Doctor's position in time and space there is a period of malise for the Doctor and his companions. The Doctor is spending all his time fixing the Time-Space Visualiser, Barbara is making a dress, Ian is reading and Vicki is at something of a loose end. Eventually this peace is broken by an ear-splitting shriek from the Time and Space Visualiser. The Doctor explains to his companions that the machine is something like a Time Television, which allows you to se any event that has happened in the past. They each choose an event to witness: Ian picks Abraham Lincoln giving his Gettysburg Address, Barbara elects to look into Elizabeth I's court, and sees the genesis of William Shakespeare's plays 'The Merry Wives of Windsor and Hamlet; and Vicki sees the Beatles performing "Ticket to Ride", but is surprised that they should play "classical music". This experimentation is interupted when the TARDIS begins to materialise. The four travellers find themselves on an arid and desolate planet which possesses two suns that move quickly across the firmament. The Doctor suggests that days and nights must be very short here. Ian and Vicki head into the desert wilderness, the former entrusted with the "TARDIS magnet" in case they should get lost. Vicki investigates some formations in the shape of humans similar to seaweed, which Ian knows is impossible. They find a trail of what appears to be blood in the sand, which Vicki runs off to follow. As they move off, they do not notice a tentacle rise up from the sand where they were.

Meanwhile, the Doctor and Barbara sunbathe. Barbara is distracted by the sound of the Visualiser, which has not been shut off. She sees a "broadcast" of the Daleks preparing a report. The Doctor enters and hears to his horror the Daleks' plan to follow "the enemy time machine" (the TARDIS) to the Sagarro Desert on the planet Aridius which is where the Doctor has found himself. The Dalek assassins plan to use their time machine, find the Doctor and his companions, and exterminate them due to the fact that the Doctor is the only person that stands in the way of their ambitions to take over Earth. The Doctor and Barbara watch a group of Daleks embark into the machine and dematerialise. The Doctor informs Barbara that these events must have happened in the past for the Time and Space visualiser to be able to show it which means that the Daleksare already on there way. The Doctor and Barbara agree they need to find Ian and Vikci and leave the planet immediatley.



Tiring from their walk, Ian and Vicki take a rest as the "blood" trail ends, by this time night has fallen very quickly. They find a large metal ring. At first, Vicki is reluctant to disturb it for fear of what might happen (due in no small part to a myth from her childhood wherin pulling a ring in a field would lead to a drawbridge on a mysterious castle to open). However, they decide they should pull it loose. At first, nothing happens and they prepare to leave, but an ancient trap door creaks open in the sand. They enter the newly-opened cavern to have a look. Once inside, the door close behind them: they are trapped - and another tentacle looms out of the darkness. As they turn they see a mysterious figure looming in the darkness.

The Doctor and Barbara have had no luck finding their friends, night has fallen, and the wind has begun to pick up, covering all tracks, including their own. They decide to return to the TARDIS, not entirely certain of the direction. A sandstorm breaks out, the Doctor and Barbara fall to the ground. When the suns come back up again they look around for the TARDIS but to no avail. They speculate that it has been covered in sand. They are about to leave when they see a Dalek, buried by the sandstorm, emerging from the sand.

The Death of Time (2)


As Barbara and the Doctor duck out of th way two more Daleks appear, but cannot find the time travellers. As the two Daleks leave to look for the time travellers the Doctor and Barbara get up to go. As they mount the crest they have been hiding under they are faced by a group of bipedal lizard like creatures.

Meanwhile under the surface of Aridius, Ian and Vicki escape the oncoming hoarde of lizard like creatures that pursue them through the labyrinthine passage ways - often having to attack the creatures with rocks in order to escape their clutches.

Back on the surface the creatures introsuce themselves as Aridians. They explain that the whole of Aridiud used to be under water but as the two suns got closer to the planet the water evapourated leaving only the Aridians and the Mire Beasts. The Aridians explain that the Mire Beasts have taken over the Aridians underground cities and left them to dieout in the harsh sunlight. When the Doctor deduces that Ian and Vicki must be in the subterreanean Aridian cities the Aridians state that they cannot go there as the Aridians are launching an assault on the Mire Beats blowing up some of there underground strong holds. The Doctor and Barbara are insistent and the Aridians try and get them to the enterance before the explosion. Unfortunatly they do not make it in time.

The explosion proves a mixed blessing for Vicki and Ian. Just as the explosion resonates throughout the tunnels Vicki is grabbed by a Mire Beast. The beast is instantly killed by the explosion but a rock lands on Ian's head knocking him unconcious. Vicki goes to find the Doctor, leaving Ian prone in the tunnel network.

The Daleks search for the time travellers, killing or enslaving any Aridians that get in their way. They use a hoarde of Aridian slaves to dig out the TARDIS which they have located using a sesmic resonator. Once they have released the TARDIS the Daleks kill the Aridian work force and guard the machine waiting for the Doctor to return to his ship.

Meanwhile the Doctor and Barbara are being protected from the Daleks in one of the Aridian subterreanean strongholds, however one of the Aridians comes to the Doctor to inform him that the Daleks have made contact with them and have vowed that they will stop the killing of their people if they hand over the Doctor. The Aridians tell the Doctor they can stall for two hours but will then have to hand him over.

In another part of the cave system Vicki searches for a way out. She finds an opening and clambers through it only to see the Dalek guarding the TARDIS. She soon meets up with the Doctor to inform him of this fact. No sooner has she done this but the Aridians come to hand the Doctor over to the Daleks. At this moment a Mire Creature breaks through a walled off section of the cave and seizes one of the Aridians. The trio of travellers use this opportunity to escape. Vicki leads the Doctor and Barbara back to Ian who is now concious. He too has located the TARDIS but has come up with a plan as to how to how to get to it. He covers a hole with Barbara's cardigan and the Doctor's jacket. The travellers then tempt the guard Dalek towards them by calling and hiding. The Dalek falls down the hole into the Aridian cave network. The Doctor and his companions rush into the TARDIS just as the Daleks fire at them. As the TARDISdematerialises the Daleks vow to follow their enemy across eternity in oder to destroy him.

=== Flight Through Eternity (3) ===

The chase through time and space begins, with the Daleks determined to track down and exterminate the Doctor and his friends. They are only fifteen minutes behind and the gap is closing.

The first stop is the top of the Empire State Building in New York City, where a young man from Alabama, Morton Dill, tells them it is 1966. Fortunately for him, neither the TARDIS nor the Dalek time vessel stays long and his life is not imperilled; in fact he breaks into hysterics at the sight of a Dalek, unwittingly allowing the TARDIS time to escape.

The ship arrives on another ship, a sailing ship in the Atlantic Ocean off the Azores. Barbara is enthralled, but Ian is getting seasick so he retires to the TARDIS, where the Doctor monitors the situation. Barbara is captured by a crewmember who thinks she's a stowaway, but Vicki knocks the man on the head. A second person arrives and Vicki, in her enthusiasm, does the same to him. Alas, it is Ian, and she and Barbara help their dazed friend back into the TARDIS as it takes off. The Dalek time machine arrives on their heels, and the Daleks proceed to either exterminate the crew of the sailing ship or drive them to abandon ship in terror. When the Daleks realise their targets are not aboard, they depart. The ship is suddenly silent and empty. It is the legendary Mary Celeste.

In the TARDIS, the Doctor calculates that their advantage has narrowed to only eight minutes, and will be reduced further when they next land.

Journey into Terror (4)
The TARDIS lands in a mysterious old house where ghosts, spooks, Dracula, and Frankenstein's Monster reside. These terrors stalk the building, even attacking the Daleks when they arrive. The TARDIS hastily departs in the melée of Daleks fighting the creatures. The Daleks are eventually pushed back into their vessel by the monsters. The Doctor postulates they have actually been visiting "an area of human thought... neither time nor space." In fact, they have simply been visiting a "House of Horrors" at the Festival of Ghana in 1996; the creatures were robots.

In the confusion, the Doctor, Ian, and Barbara leave without Vicki. They are utterly distraught when they discover this, knowing the TARDIS cannot take them back. Their only course to rescue her is to try to take control of the Daleks' own time vessel.

Vicki has stowed aboard the Dalek time machine, where she sees the Daleks' replicator machine in action: an android replica of the Doctor is produced and is programmed to "infiltrate and kill."

The Death of Doctor Who (5)
The Doctor, Ian and Barbara arrive at night on the planet Mechanus. When the Dalek ship arrives, the robot Doctor is dispatched. The jungle is hostile, with huge, carnivorous fungoid plants that retreat only when exposed to light. Fortunately and mysteriously, a corridor of lights appears, leading the trio to a cave. They disable the lights before the Daleks can follow them, but when they do so they are shocked to hear a scream that sounds like Vicki.

The Doctor and Ian run out to find her, armed with a light rod they discover in the cave, while Barbara remains with a machine the Doctor has built to defend them from the Daleks. The robot Doctor finds Barbara, and lures her from the cave. Barely escaping with her life, she finds Ian and Vicki... and two Doctors! They fight with their walking sticks, and the real Doctor cleverly deactivates the robot by imitating a Dalek voice, instructing it not to kill. He disconnects vital circuitry.

The Daleks are hampered by the fungoid creatures and call off their search until the morning, while the Doctor and his party sleep in the cave. As they do so, a camera is observing them.

In the morning the Doctor emerges to discover a vast metal city atop the jungle. Before they can enter the city, the Daleks attack. As the Doctor's machine is prepared for use, a false wall in the cave slides down to reveal a large, round robot in a lift. They hear the Daleks' battle-cry outside and have no choice but to accompany the robot.

The Planet of Decision (6)
The lift takes the Doctor, Ian, Barbara, and Vicki to the Mechonoid City. They are taken to a large room. The door behind them is closed and locked. In the room is a dishevelled human survivor named Steven Taylor, an astronaut from Earth who crash-landed on the planet two years earlier and has been kept as a prisoner by the Mechonoids. They are colonising robots here to build the city for humans who never came and without the correct code, the new arrivals will never be released. The Daleks find the cave empty, but soon locate the lift and enter the city. The Mechonoids and Daleks fight a pitched battle which devastates both sides and destroys the city.

Before this happens, the five prisoners flee to the roof, where they use a massive cable to scale down fifteen hundred feet to the surface. They are separated from Steven, who insists on saving his "mascot," a stuffed panda named Hi-Fi. Steven makes it to the surface, and desperately searches for the Doctor.

The TARDIS crew find the deserted Dalek time machine. Ian and Barbara realise they can finally return home to their own time and place. The Doctor angrily resists, but the others persuade him to show Ian and Barbara how to operate it. After a tearful farewell, the two schoolteachers are safely delivered home – not to their own time, but two years out in London of 1965. The time machine is destroyed with an auto-destruct mechanism.

The Doctor and Vicki witness this "history" on the Time-Space Visualiser, with joy and sadness. The two depart in the TARDIS.

Daleks

 * The robots in the funfair are impervious to Dalek firepower.
 * This is the first example of the Daleks having time travel.
 * This is the first use of the Dalek using replicant technology.
 * The Daleks appear to be under the impression that the Doctor is from Earth, as they refer to "the Earth time machine" in "Flight Through Eternity", and in "The Death of Time", the Supreme instructs his comrades to "find the Humans."

TARDIS

 * The first reference is made to the time rotor.
 * The Doctor uses the time path indicator.
 * The Doctor explains to the others it takes twelve minutes for the TARDIS's flight computer to re-orientate itself and 'gather power', thus limiting the speed with which they can make each new jump.
 * In episode 3 the Doctor references a scanner that has been in the TARDIS "since I constructed it". The "it", however, isn't very specific. It could be that the Doctor is referencing that the scanner has been in the TARDIS since he built the scanner, or he could be implying that he actually built the TARDIS, although later stories would appear to contradict this.

Story notes

 * All episodes exist as 16mm telerecordings.
 * Negative film prints were recovered for all episodes in 1978.
 * This story went under the working title The Pursuers.
 * The story was commissioned at late notice when another of Terry Nation's stories fell through. It is believed that the slot was originally to be filled by his planned historical The Red Fort.
 * The scenes in episode 6 with Ian and Barbara celebrating their return to London was made as part of the production block for The Time Meddler and the director for these is consequently Douglas Camfield.
 * This is one of the few Dalek stories to incorporate humour. Examples includes a stammering Dalek who cannot do simple mental arithmetic (in the first two episodes); Daleks nodding their eyestalks to confirm a plan (in the fifth episode); and showing a trait for deviating from the subject at hand (during their deliberations in the first episode).
 * Morton Dill, the young man from Alabama whom the travellers meet at the top of the Empire State Building, was played by Peter Purves, who appeared in the last episode as Steven Taylor.
 * The story also features The Beatles in a film clip. Ironically, considering the number of lost Doctor Who episodes, the Beatles performance from which this clip was taken now only survives in this story. (In a double irony, the scene has once again been "lost" as licensing restrictions forced it to be deleted from the Region 1 DVD release.)
 * The Beatles were originally planned to appear as old men performing in the 21st Century but this proposal was vetoed by their manager Brian Epstein. Had this gone through, of course, it would have become an anachronism given the fates that would befall both John Lennon and George Harrison before they got to be "old men".
 * This story includes the joke that, in the future, contemporary pop musicians such as the Beatles would be considered classical music. This joke was repeated in the series 40 years later in The End of the World. While not contemporary at the time of airing, the Beatles are once again referred to as "classical" in the story 42.
 * The Daleks are particularly poetic in this story: Dalek - "Advance and attack! Attack and destroy! Destroy and rejoice!"
 * This is the final television story featuring Ian and Barbara.
 * This is the first appearance of Steven Taylor. Actor Peter Purves became the first actor to play two completely different roles (without the use of heavy makeup or prosthetics) in the same story. He also became the first actor to appear in a guest-starring capacity before being offered a regular role. This next occurred when Ian Marter appeared in Carnival of Monsters two years before joining the series as a different character, Harry Sullivan, in Robot. The fact that Purves played two different roles, one to become ongoing within the same story, however, remains a unique circumstance.
 * The Chase was earmarked to form the basis for a third "Dr. Who" film starring Peter Cushing, to follow Daleks' Invasion Earth 2150 A.D., but the film was never made.
 * Episode 5 carries the title "The Death of Doctor Who"; this is one of only two occasions in which the technically incorrect name "Doctor Who" is used in an on-screen title (the other occasion being the seven episodes of Doctor Who and the Silurians in 1970).
 * During rehearsal the three fungoid costumes were given nicknames to avoid confusion; Fungoid Fred, Toadstool Taffy and Mushroom Malone.
 * The three main pillars of the Mechanus forest set were referred to in the script as the "Gubbage Canes".
 * A later novel, EDA: Interference - Book One, would establish that the Dracula and Frankenstein robots were built by Microsoft, although the company wasn't established until a full ten years after The Chase was broadcast.
 * Episode six features the first use of the Dalek battle cry of "Exterminate!" (Previously, The Daleks mentioned the term "extermination", and in The Dalek Invasion of Earth, the Supreme Dalek ordered his subordinates to "exterminate" Ian, but this is the first time the word is used as a singular exclamation.)
 * In DWM, The Chase was voted the readers least favourite Dalek story.
 * The episode "Flight Through Eternity" contains a rather morbid first (remembering that Doctor Who was originally considered a children's program and still is marketed towards children as of 2011): the first depiction of the death of a child. This refers to the baby being carried by the woman who jumps off the Mary Celeste (and, though no deaths occur on-screen, history records that the passengers of the vessel were never found).
 * This was the second serial to consist of several mini-adventures linked by an overall story arc. The first was DW: The Keys of Marinus.
 * The Frankenstein Monster's makeup is based upon the original design created by Jack Pierce for the original Boris Karloff films.
 * The Dalek dialogue from the battle scenes in Episode 6 is reused from Episode 1's scene of the Dalek Supreme sending the Executioners.

Myths

 * The scene showing Ian and Barbara on the bus was shot on location. (The scene was actually shot at Ealing Studio with a back projection active behind the bus to give the impression of movement.)
 * A third Dalek film starring Peter Cushing, based on DW: The Chase and titled Daleks vs. Mechons, was filmed but subsequently lost in a fire. A trailer discovered in the basement of a church in northern England in 2009. The supposed "trailer" was fanmade, as the graphics were too advanced for circa 1967. Although a third film was planned as an adaptation of "The Chase", it was shelved with no work done following the second movie's failure at the box office.

Filming locations
to be added

Production errors

 * At the beginning of "The Executioners", Ian seems to know the words to The Beatles' song, "Ticket to Ride". This would seem to be inconsistent, as he left England in 1963 and "Ticket" wasn't released until April 1965. While it's possible he learned the song at some point during his travels, this is inconsistent with a major plot point that Ian and Barbara have been away from present-day Earth for two years. Ian could have learned the lyrics from Vicki, who loves the Beatles.
 * Later in "The Executioners", Vicki and Ian cast shadows across the backdrop painted like a desert.
 * An Aridian can be seen getting up and sneaking off camera after being knocked over by Vicki in "The Death of Time". Perhaps he's running off to get help or tell the elders what's happened.
 * In "The Death of Time," when Ian discovers the TARDIS and its two Dalek guards, he ducks back down underground. He does not see the scene where one of the guards is pulled off to search, so he should be unaware that there is now only one Dalek guard when he meets his friends.
 * When the travellers are trying to lure the Daleks away from the TARDIS in "The Death of Time", there is poor continuity as the scene is set at night yet one shot shows a Dalek falling down in daylight. This has been altered for the DVD by Doctor Who Restoration Team by regrading the shot, however the production notes subtitles were not updated and reference the error.
 * At the beginning of "Flight Through Eternity" in the Dalek Time Machine two of the Daleks are missing their bases. These are "movie" Daleks with alterations made to more closely resemble the "TV" models.
 * In "Flight Through Eternity," Vicki is shown climbing on top of the ship's cabin to knock out the sailor and (accidentally) Ian. A few moments later the camera moves to reveal that she was in direct line of sight of the sailor manning the ship's wheel and should have been spotted.
 * When the Mary Celeste model is moving no water is displaced.
 * As the TARDIS lands at the beginning of "Journey Into Terror," a candelabra moves a few feet to the left.
 * The string controlling the bat that lands on the stairway railing is very obvious. But as the bat is fake within the storyline in any case, it suffices that the string may be less obvious to the characters than it is to the TARDIS crew.
 * As Ian and the Doctor descend the stairs where Frankenstein lies, a camera and operator can be seen clearly in shot at the top of the stairs.
 * One of the Daleks can be seen in Frankenstein's lab before they have supposedly arrived. Vicki can also be heard talking in the background just before the scene ends.
 * Frankenstein's Monster has no jacket in one scene, then has a jacket in the next scene.
 * Whilst moving across the screen in "Journey Into Terror," a countdown is projected across one of the Daleks as it trundles "behind" the display. This has been corrected on the remastered DVD release.
 * In long-distance shots, the Daleks' "exact duplicate" of the Doctor actually looks very little like him. Up close, William Hartnell plays the duplicate as well, however at the end of "Journey into Terror" the camera cuts to a closeup of Hartnell delivering the final line of the episode, with a completely different background than that in the previous shot. Also, the robot double's lip movement is not at all in sync with the pre-recorded Hartnell dialogue. This could be passed off with the fact that it is a Robot trying to fabricate speech poorly.

Continuity

 * When Ian asks Barbara for her cardigan for use in his plan to make a trap for the Dalek guarding the TARDIS, she says, "Oh no, not again." Another of her cardigans was sacrificed in The Space Museum.
 * This is the first appearance of Dalek replicant technology. It would be seen again in Resurrection of the Daleks.
 * The Empire State Building is used as a location in another Dalek story, Daleks in Manhattan/Evolution of the Daleks. In this story, it's suggested that the Daleks had a hand in constructing the Empire State Building, at the very least designing the top few floors, which is indeed the case in that latter story. The Daleks featured in the two stories are most likely not aware of each other, because the plot of Manhattan/Evolution hinges on a post-Last Great Time War state of affairs.
 * The Mechonoids appear again, resurrected by Davros in BFA: The Juggernauts.
 * The Daleks' ability to time travel is referenced again in DW: The Daleks' Master Plan, The Evil of the Daleks, Day of the Daleks, Resurrection of the Daleks, Remembrance of the Daleks, Doomsday, Daleks in Manhattan, The Stolen Earth and Journey's End.
 * The alien known as Mila, first appearing in BFA: Patient Zero, claimed to have been in the TARDIS since this story.
 * Ian and Barbara return in PDA: The Face of the Enemy as husband and wife.
 * The Daleks refer to the Doctor as "human" again in DW: The Daleks' Master Plan. It wasn't until DW: Resurrection of the Daleks that his true species designation was acknowledged by them on-screen.
 * A robot recreation of Dracula is seen in the House of Horrors at the Festival of Ghana in 1996. The Fifth Doctor would later meet the historical Dracula, also known as Vlad the Impaler, in 1462 (BFA: Son of the Dragon) whereas his sixth incarnation met his literary vampire namesake in the Land of Fiction (BFA: Legend of the Cybermen).

Novelisation and its audiobook

 * Main article: The Chase (novelisation)


 * This story was novelised as The Chase by John Peel, and was published by Target Books in July 1989. It was the first of several Dalek story novelisations Peel would write after Target came to an agreement with Terry Nation.
