This topic might have a better name.

Shada (unproduced TV story). Adding a rename tag rather than simply renaming because this article appears to also cover the home video, which should be in a separate article as an "adaptation"

You may wish to consult Shada (disambiguation) for other, similarly-named pages.

Shada was the intended final story of Season 17 of Doctor Who. It was to be the final story written by Douglas Adams for the series, the final six-part story until TV: Dreamland in 2009, and the last story to feature Graham Williams as producer, as John Nathan-Turner would take over after this until the end of the series run in 1989.

However, a combination of rampant inflation in Britain and union strikes halted production partway through filming. The story would become infamous for its incomplete nature and would lead to several attempts to create stories using the unpublished material. It was the basis for Dirk Gently's Holistic Detective Agency, a non-Doctor Who branded book published by Adams in 1987 that was the start of the Dirk Gently book series.

The parts of the story that were filmed were retained, and John Nathan-Turner was able to reuse them later in two notable ways. In 1983, a few clips from Shada were integrated into TV: The Five Doctors for the scenes with the Fourth Doctor when Tom Baker proved unavailable for filming.

Later, on 4 February 1992, the existing footage was integrated with some new linking narration by Baker for a special BBC Video release on 6 July 1992.

The story was remade by Big Finish as a webcast story by the same name for release in May 2003, and later on 21 November as audio story using the same name. Both featuring Paul McGann as the Eighth Doctor.

Finally, in 2017, a "completed" edit of Shada was reconstructed, with a mix of live-action and animated material. Voice work was recorded on 9 and 13 July 2017, and Baker recorded an extra live-action sequence on 13 September. The final edit used production material recorded across 1979, 1992 and 2017, and became avaliable for digital download in November 2017.

The story finally was aired on television for the first time on 18 July 2018, on BBC America. This marked thirty-eight years, nine months and three days between the beginning of filming and the airdate, a record for any episode of Doctor Who.

A revised version, in the original intended format with cliffhangers intact, was released on 20 December 2021 on the Season 17 set of The Collection; this edition was also made available on the BBC iPlayer on 1 November 2023.


Shada: a prison built by the Time Lords for defeated would-be conquerors of the universe. A scientist named Skagra needs the help of one of the prison's inmates. He finds nobody knows where Shada is anymore, except one aged Time Lord who has retired to Earth, where he is a professor at St Cedd's College. Luckily for the universe, Skagra's attempt to force the information out of Professor Chronotis coincides with a visit by the professor's old friend, the Fourth Doctor.


Part one[]

Shada - creation of sphear

The sphere is created.

On the Think Tank space station, a scientist named Skagra uses a spherical device to drain the minds of his colleagues and departs in his spaceship for Earth, leaving an automated, repeating quarantine message running: "This is a recorded message. The Foundation for the Study of Advanced Sciences is under strict quarantine. Do not approach. Do not approach. Everything is under our control."

At St Cedd's College in Cambridge, 1979, Professor Chronotis has a visit from an academic he met at a faculty party, Chris Parsons, who asks to borrow books on carbon dating but leaves with the wrong book. The Doctor and Romana are enjoying a spot of punting. They're observed by Skagra and distracted by voices from the sphere he's carrying. They visit the Professor.

In the physics lab, Chris discovers that the book is written in a completely alien script. He analyses the book with instruments that make it smoke and glow. Chronotis reveals to Romana he is an elderly Time Lord who has retired to Earth and has been living in the same Cambridge rooms for three hundred years. The Doctor asks him why he was summoned by him to Cambridge but the Professor can't remember. He later recalls he needs the Doctor's help finding the book.

Wilkin, the college porter, is updating a notice board when Skagra — dressed in a distinctive white and silver outfit, with a wide-brimmed hat — arrives and arrogantly demands to see Chronotis. Naturally, Wilkin takes a dislike to this ill-mannered stranger and tells him the Professor will not want to be disturbed; he is with the Doctor, a "very old friend". A rebuffed Skagra leaves.

Skagra gets a lift in a car, uses the sphere to steal the driver's ability to drive, and then takes the wheel himself. The Professor reveals the missing book is one he brought from Gallifrey. Skagra drives out to a field where his spaceship is concealed, invisible to the human eye. The Professor confesses the book he took was The Worshipful and Ancient Law of Gallifrey, which dates back to the time of Rassilon and has incredible power. Skagra receives word that all is ready from his carrier ship, commanded by a massive Krarg...

Part two[]

The Doctor and Romana search the Professor's rooms for the book. They discuss Time Lord law. This reminds them of the Time Lord criminal Salyavin, a boyhood hero of the Doctor. The Professor, asked about his contemporary Salyavin, recalls Chris Parsons' visit and wonders if he has borrowed the book by accident.

Shada - Timescoop

Chronotis's mind is stolen.

Chris and his friend Clare Keightley analyse the book as the Doctor cycles across Cambridge to the lab. Skagra, now wearing the car driver's contemporary clothes, comes to the Professor's college seeking him. While Romana looks in the TARDIS for milk so they can have tea, Skagra arrives for the book. He sets the sphere on the Professor, stealing part of his mind. The Doctor meets Clare at the lab, and examines the book.

Romana and K9 Mark II find the collapsed Professor as Chris Parsons arrives. Using the TARDIS medical kit, Romana tries to stabilise the Professor's condition. The Doctor and Clare discover that the book carbon dates as minus twenty thousand years old. Skagra scans his copy of Professor Chronotis' mind for a trace of the book but finds nothing. The professor beats out a message to Romana on his hearts in Gallifreyan morse code, telling her to beware of the sphere, Skagra and Shada, but dies before he can reveal where the secret is.

Shada - tbc

The Sphere catches up with the Doctor.

Skagra meets the Doctor trying to return the book to the Professor and has a sphere pursue him on a bike through Cambridge. During the chase the book is dislodged from his basket and retrieved by Skagra. Forced to run away, the Doctor is cornered by the sphere. He tries to escape under a gate, but the sphere approaches and begins to steal his mind...

Part three[]

Romana arrives in the TARDIS to rescue the Doctor. In Chronotis' rooms, Chris moves to close the Professor's still-open eyes, which are troubling him, but as he tries to do so, the body vanishes. The TARDIS returns, and Chris tells the Doctor and Romana what happened. The Doctor says Chronotis must have been on his very last regeneration, and decides he needs to speak with Skagra. K9 tracks the sphere to Skagra's ship. Clare, worried about the danger the book may pose, comes to Chronotis' rooms to find them empty. Scared, Clare runs out and comes across Wilkin, telling him about the "dangerous" book but he naturally finds her tale hard to believe. However, Wilkin offers to see if he can locate Chronotis, and Clare goes back to the Professor's rooms.

The TARDIS materialises in an apparently empty field which holds Skagra's invisible ship. They enter and suddenly, Romana, K9 and Chris vanish in a cube of light; Skagra has taken them prisoner. He tells them he was interested only in Chronotis' mind. He tries to force the Doctor to decode the book and sets the sphere on him to take his mind. K9 fails to blast out of the cell he, Romana and Chris are held in. K9 picks up the Sphere's signals and detects the Doctor amongst its voices. Suddenly, the cube of light transports Romana from the cell, leaving Chris and K9 behind. Romana is taken to the TARDIS by Skagra, who forces her to take it.

While searching the Professor's rooms for the missing book, Clare finds concealed control panels and accidentally triggers an explosion. The Doctor awakens on the ship and explains to its computer how he survived. The sphere took only a copy of his mind.

Shada - missing room

Wilkin discovers Professor Chronotis' room has been stolen!

Wilkin comes to the Professor's rooms to tell Clare he has been unable to find Chronotis. He knocks, but there is no answer. Wilkin opens the door, only to find not the room but the swirling Time Vortex. The Doctor tries to persuade the Ship to release his companions and him, but it decides the sphere must haves succeeded in its task and killed the Doctor. To conserve resources, the Ship turns off the oxygen supply, As the Doctor collapses slowly to the floor, the ship states "Dead men do not require oxygen..."

Part four[]

The cube of light transports Chris and K9 from the cell. The Ship detects them and reactivates its oxygen supply, announcing "Oxygen levels returning to normal." The TARDIS arrives at the Krarg carrier ship and Romana sees the Krargs being grown in a generation annexe. Another Krarg starts to form in a smaller version of the generation annexe on Skagra's ship. The Doctor boosts the Ship's power to allow it to cross space quickly.

In Professor Chronotis' rooms, Clare awakes. She is startled by the Professor, dressed in an old-fashioned nightcap and nightshirt. Skagra is unable to translate the book with the Doctor's mind in the sphere. The Professor explains to Clare that his rooms are his TARDIS and it interfered to save his life.

The Professor decides they must find Skagra to save the book, which is the key to Shada, the Time Lord prison which has been forgotten. The Doctor and Chris are attacked by a Krarg, but K9 holds it off, allowing them to explore the Think Tank complex where they have arrived. (The automated quarantine message is still playing, but is now naturally worn and distorted.) They find the aged, mindless figures of Skagra's former colleagues.

Skagra notices that turning the pages of the book influences the TARDIS. He realises turning the last page of the book will take him to Shada where he will find the Time Lord criminal Salyavin, who is crucial to his plans.

The Doctor attaches Chris to the mind resource equipment to link Chris's intelligence reserves to the memory patterns of one of the scientists, the neurologist Caldera; Chris passes out when the Doctor activates the control console. Caldera explains to the Doctor how Skagra — or "Dr. Skagra", as he was known to them — set up Think Tank with himself, A. S. T. Thira, G. V. Santori, L. D. Ia and R. F. Akrotiri to pool the resources of the mind electronically, but when they had completed the sphere he used it to steal their minds. Skagra now intends to use his mind to dominate the whole of humanity, but needs Salyavin to accomplish this. Caldera then passes out and the Doctor checks on Chris, who comes to. K9 loses his fight against the Krarg and is driven into the Think Tank by the massive creature, which now advances on the Doctor...

Part five[]

The Krarg strikes the machinery in the Think Tank, creating explosions and a huge cloud of smoke, before it strikes down and kills the scientists. This allows the Doctor, K9 and Chris to escape back to Skagra's ship, leaving just as the Think Tank station explodes. The Ship is persuaded to take the Doctor to Skagra's home.

Shada - hypnotism

The Professor places the TARDIS repair knowledge into Clare's mind.

While trying to repair the Professor's TARDIS, Clare asks Chronotis who Salyavin is. The Professor places the knowledge that Clare needs to effect repairs into her head telepathically, and she is suddenly able to correctly identify the piece of equipment she is holding; only a moment before, she had no idea what it was.

Skagra's ship takes the Doctor to the Krarg carrier ship. They are captured and Skagra reveals his plan to take over the universe telepathically, merging them into one mind: his. The Doctor stages an escape with Chris and K9, but Romana is dragged back to the TARDIS by Skagra.

Shada 2017 animation


Fleeing down the metallic corridors of the ship, the Doctor, Chris and K9 discover an incongruous old wooden door and go through it — finding themselves in Professor Chronotis' college room/TARDIS. The Professor knows that with the book and the Doctor's TARDIS, Skagra can travel to Shada, which is exactly what he does. Skagra searches Shada's records for Salyavin, the Time Lord criminal.

The Professor's TARDIS arrives with K9, the Doctor and him. Skagra revived the following prisoners in chamber T when the Doctor arrives: the orange insectoid #547, the Boudica-like #595, the cyborg #590, the Nero-like #512, the Genghis Khan-like #568, the Rasputin-like #504 and the purple man #503. Among the cryogenic cells' shadows also are an Ice Warrior and a Zygon silhouettes. But when Skagra opens Salyavin's cell, cabinet 9, they find it empty. The Professor admits he is Salyavin: he escaped centuries ago and used his powers to make the Time Lords forget about Shada.

The Sphere attacks the Professor, but is destroyed by K9. However, it reforms into several smaller spheres — one of which attaches itself to the Professor, who sinks to the floor. The spheres then attach themselves to the revived prisoners, bringing them under Skagra's control. Chris and Clare arrive, but Chris is taken under the control of a sphere. Skagra tells the Doctor they will now deal with him. The prisoners, along with Chris, advance menacingly towards the Doctor...

Part six[]

K9 fires at the prisoners, driving them back, but he is picked up and thrown aside by a Krarg. The Doctor, Romana and Clare grab K9 and flee to the Professor's TARDIS. Romana reminds the Doctor that his mind is inside Skagra's machine too. Skagra returns to the TARDIS and tells the former prisoners that they will return to the carrier ship and be distributed through the universe to further his revolution.

The Doctor follows his TARDIS in the Professor's. He captures it in a force field and has himself placed into the Time Vortex. The Doctor begins crossing to his TARDIS, but his journey appears in vain. An accident occurs in the Professor's TARDIS, deactivating the force field, throwing the Doctor into the vortex.

Shada TARDIS Transfer

The Doctor's return to his TARDIS through the vortex.

The Doctor finds himself in a workroom in his TARDIS, where he starts building a helmet-shaped device from various components he gathers together, as well as a chunk of tabletop. The Professor's TARDIS arrives on the carrier ship as the Doctor — wearing the ridiculous-looking helmet — reveals himself and struggles for control of the joint mind.

Romana deactivates the Krarg generating equipment, tipping the gas out and using it to destroy the Krargs. Skagra flees to his ship, but the cube of light transports him to the cell where Romana, K9 and Chris were held prisoner. He demands the Ship lets him out, but the Ship tells him it can no longer accept his orders as it has now decided to serve the Doctor. The Ship offers to tell its former master all about the Doctor; Skagra responds by sinking to the floor, sobbing "Let me out! Let me out!" The Ship chuckles.

The Doctor promises to return the prisoners to Shada and summon the Time Lords. He returns his and the Professor's TARDISes to Earth. This confuses Wilkin who, having reported the Professor Chronotis' room stolen, has returned with a policeman to find the room back in its usual place, and the Professor taking tea with his guests. The policeman then spots the TARDIS and asks about it. The Doctor says it's his, and he and Romana say goodbye to everyone and leave in the TARDIS. After the TARDIS has dematerialised, the policeman asks where the police box has gone. When Chronotis replies "What police box would that be, officer?", the policeman — having had enough of stolen rooms and disappearing police boxes — tells everyone to get their coats on; they're coming with him "down to the Bridewell" — i.e. the police station.

Shada 2017 Doctor

A temporarily aged Doctor wonders if, in 200 years' time, someone will meet him and ask themselves "Is that really the Doctor? He seems such a nice old man."

Aboard the TARDIS, the Doctor — now wearing his light brown tweed coat — and K9 are tinkering under the console; and Romana asks where Skagra was from. The Doctor responds that Skagra was from the planet Dronid, according to K9's analysis. Suddenly, a small explosion occurs under the console. Romana then asks if the stories about Salyavin were exaggerated by the Time Lords, since the Professor seemed like a nice old man to her. The Doctor says the Time Lords overreact to everything, The Doctor then emerges from under the console, briefly appearing much older and wonders if someone will meet him 200 years in the future and ask themselves "Is that really the Doctor? He seems such a nice old man." He looks towards the audience, and smiles.

Theories and concepts[]

People from the real world[]

  • Whilst punting down the river, the Doctor mentions Isaac Newton while rambling to Romana.

Time Lords[]

  • Salyavin was a notorious, mind-controlling criminal and a semi-hero of the Doctor's in his youth. He was sentenced for "mind crimes" to the Time Lord prison Shada.
  • Chronotis was on his last regeneration when he died, but he is brought back to life by Clare mucking around with his TARDIS.
  • The Worshipful and Ancient Law of Gallifrey dates back to the days of Rassilon, and is one of the "artefacts".
  • Chronotis is able to beat out a message with his hearts in Gallifreyan Morse code.
  • Retired Time Lords are not allowed to have access to a TARDIS.
  • After reminding the Doctor that part of his mind is still in the sphere, Romana receives a medal from the Doctor.


Story notes[]

  • Douglas Adams chose Cambridge as a setting so he could draw on his experiences as a student at the university.
  • The story takes place in October 1979. Coincidentally, that is the same month Douglas Adams published his first The Hitchhiker's Guide to the Galaxy novel. It was also during production that Doctor Who Weekly launched.
  • Douglas Adams later used elements from this story in his novel, Dirk Gently's Holistic Detective Agency.
  • The cast for Shada's prisoners, though not called back for the eventual release, was originally intended to be: (DWM 267)
  • Those scheduled to perform the Krargs in the remaining unshot scenes were: Harry Fielder (Krarg Commander), Reg Woods, Lionel Sansby and James Muir. (DWM 267)
  • Those scheduled to perform the Lab technicians in the unshot scenes were: Roger Neate and Nicky Ryde. (DWM 267)
  • Doreen James was supposed to design the costumes, but she'd quit the series following a dispute with Lalla Ward on TV: City of Death.
  • The famous scene where the Doctor is chased by the orb while on a bicycle was supposed to take place at night.
  • Douglas Adams named the characters of Chris Parsons and Clare Keightley after his friend Chris Keightley, president of the Cambridge Footlights.
  • The Think Tank space station scientists all bore names associated with Greek islands: Caldera, Akrotiri, Ia, Santori and Thira.
  • The part one joke in which Professor Chronotis forgets that he has "a memory like a sieve" was taken from a story of Douglas Adams's that had been published in the February 27th, 1965 edition of Eagle and Boy's World, when he was just twelve years old.
  • Graeme MacDonald suggested a romantic subplot between Romana and Chris, but this was ignored.
  • Michael Hayes was originally supposed to direct.
  • While in a pub, Tom Baker and Pennant Roberts were approached by the secretary of the St John's Choristers, who enquired as to whether Doctor Who might make use of his choir's services. Roberts agreed and included the Choristers — singing "Chattanooga Choo-Choo" — as part of the chase scene the next day; Baker was made an honorary fellow of St John's College in return.
  • When Skagra examines the Doctor's life, brief clips from TV: The Pirate Planet, The Power of Kroll, The Creature from the Pit, The Androids of Tara, Destiny of the Daleks and City of Death are shown. Romana I is visible in some of the clips, marking one of only two times that both Romanas appeared in the same television story (the other being the pre-regeneration flashbacks at the end of TV: Logopolis).
  • The medal that the Doctor presents to Romana is a French “Ordre de l'Économie Nationale” which was created on January 6th, 1954 and was discontinued, ironically, in 1963.
  • At first, Graham Williams felt that the Time Lords had been overexposed, before deciding to make the story a commentary on capital punishment.
  • The Krargs were initially called Kraags -- an anagram of the name of the main villain, Skagra.
  • Santori was named after the island of Santorini, which was also called Thira and was formed from a volcanic caldera. Both Akrotiri and Ia were villages there.
  • Tom Baker had considerable difficulty manoeuvering his boat, much to the consternation of Lalla Ward and the amusement of the spectating undergraduates.
  • Tom Baker was thrilled to learn that Gerald Campion had played Billy Bunter in Billy Bunter of Greyfriars School, having seen the show as a teenager. He was also doubly thrilled when he found out that Campion was a relative of Charlie Chaplin, one of Bakers idols.
  • The scenes at St. Cedd's were supposed to be filmed at Douglas Adams's own college at St. John's College, but they denied permission.
  • During rehearsals, many of the cast members contributed additional comedy material.

A lost story[]

  • Shada was initially not completed due to "labour action" at the BBC. The footage that was shot was released on BBC Video in 1992, featuring linking narration by Tom Baker to complete the story.
  • The industrial action occurred due to conflict over which union had jurisdiction over the operation of an elaborate clock that was featured on the BBC children's programme Play School (1964-1988). (DOC: A Matter of Time)
  • Pennant Roberts had booked two lighting crews for the ambitious nighttime chase sequence which was intended to form the climax of episode two. His plan was to tape a scene with one team while the other went ahead to set up the next location. However, the unions recognised Doctor Who as an important target, so they summoned the lighting chargehand back to London. As a result, Roberts had to abandon a planned shot of the Doctor travelling to the Cavendish Laboratory in Cambridge, where Chris was meant to have his lab. In the end, the chase takes place in the daytime.
  • Douglas Adams was happy that the story was abandoned, because he thought it was not up to much. In 1992, Adams signed the video rights for Shada by mistake — allowing the BBC to make a direct-to-video version, with linking narration by Tom Baker. Subsequently, Adams requested that his name be removed from the video sleeve and donated his royalties to Comic Relief. (See also VHS releases below.)
  • Had this story been broadcast when originally intended (from 19 January to 23 February 1980), this story would have marked the end of the following features of the show:
  • Had this story been televised, it would have marked the first time the Gallifreyan language was spoken in a televised story.
  • One working title for this story was "Sunburst".[1]
  • Chronotis originally perished in part two, but Douglas Adams had become fond of the character and decided to bring him back.
  • Daniel Hill, who played Chris Parsons, met his future wife Olivia Bazalgette (she was the production assistant) during the location filming of this story. They married two years later.
  • The story would be remade in 2003 and released as WC: Shada and AUDIO: Shada, explaining that Borusa's meddling in the Fourth Doctor's timeline during TV: The Five Doctors caused the events following his and Romana's arrival in Cambridge to not take place until the Eighth Doctor and Romana came back to complete them.
  • John Nathan-Turner considered remounting the serial in two fifty-minute episodes to air during Christmas 1980. This was opposed by Christopher H. Bidmead, who felt that it was keeping out of the more serious tone that they were looking to take the show in. Plans for this remounted version moved forward, and it was intended that a minimal cast would reunite for a pair of two-day studio blocks. This plan was ultimately abandoned due to lack of studio space.
  • In 1984, Noel “Snowy” Lidiard-White of BBC Enterprises suggested to John Nathan-Turner that the serial might be readied for release on home video. In November 1985, Nathan-Turner mooted the possibility of having Colin Baker fill in the missing material either with linking narration or in on-screen segments in which the Sixth Doctor would be telling the story to Peri. Nothing came of these ideas.


  • In 2017, a completed version of Shada was finally released, with unfilmed scenes replaced with animation and dialogue recorded by the original cast.
    • Due to the actors David Brierley and Denis Carey having passed away in the years since the original studio shoots, a few changes had to be made regarding unfilmed scenes featuring their characters — specifically, a scene with K9 in the TARDIS was cut completely (his dialogue in the finished product is minimal and consists entirely of archival audio of Brierley), and Professor Chronotis is completely silent in the scene in which he appears on Shada, communicating solely through nonverbal telepathy; his revealing himself to be Salyavin was rewritten so that the Doctor is the one to say it, using recycled audio of Carey's role as the Keeper from TV: The Keeper of Traken to provide Chronotis' response in the affirmative.
    • This is Baker's first time playing the role of the Fourth Doctor in a televised story since the series of in-character advertisements in 1997.
    • The TARDIS interior scenes used the season 20 console constructed for the 50 Years trailer. It had been restored by Mark Barton Hill with components of the original console he collected along the years and was also on display at the Doctor Who Experience (London/Cardiff) until it closed down'.[2]
    • There was another minor change during the scene in part two where Romana emerges from the TARDIS with a bottle of milk. Her original dialogue was "I've got the milk! Come on, K9", but this was changed to "I've got the milk! Professor?" However, K9's reply of "Coming, Mistress" was strangely retained.
    • In the animated scenes of Chris Parsons’ lab, one of the other books seen repeatedly on his table is “Zaphod - My Story”, a reference to Douglas Adams’ character Zaphod Beeblebrox from The Hitchhikers Guide to the Galaxy.
  • This story was later released as part of The Animation Collection.


  • Professor Chronotis' TARDIS is a Type 39. (The type and model of Chronotis' TARDIS is not specified in the script or the surviving footage. In the 2012 novelisation by Gareth Roberts, the Doctor identifies it as a "Type 12, Mark 1".)
  • The prisoners of Shada would have included a Zygon, a Dalek, and a Cyberman. (This rumor dates back as far as an article in DWM 45. While the script indicates that three of the prisoners are "Space monsters", no documents exist to suggest they were to be re-used costumes, or that permission was sought after from estates such as Terry Nation. In 2021, actor Steven Ismay indicated that his costume was “a heavy suit with a large, black monster face”, which does not match the description of any of the three rumoured monsters[3])

The Shada Doctor

Tom Baker narrating the missing segments of Shada in-character as the Doctor

In 1992, BBC Video released a version compiling existing footage broken down into the planned six episodes, with linking narration by Tom Baker in the part of a fourth-wall-breaking incarnation of the Doctor reminiscing about this earlier, "cancelled" adventure from his youth while wandering through a museum of the Doctor's enemies. In actuality, this linking material was recorded in a Doctor Who-themed exhibition called "Behind the Sofa" at the Museum of the Moving Image, London. Footage and still photos of a Krarg mannequin from the museum was further used in the linking sequences to represent the Krargs in the story.

No writer's credit for Douglas Adams, or any other references to him, appeared on the video sleeve — aside from a sticker reading All of Douglas Adams' royalties from the sale of this video are being donated to Comic Relief. (original printed text)

The UK release of the video included a book containing the full script of the original production, which was not included in the North American release. Unfortunately, the book's first two pages were transposed, so the Doctor Who diamond logo appeared on the second page instead of being visible through the appropriately-shaped hole in the front cover — which shows instead the wording 'DOCTOR WHO' / SERIAL 5M / 'SHADA'. To date, the book has only been included with the VHS release.

VHS release credits[]

The following additional credits appear on the VHS release after the standard Doctor Who credits, and appear over a still shot of that release's version of the Shada prison floating in space with music exclusive to that release.

Webcast version[]

Main article: Shada (webcast)

BBC commissioned Big Finish Productions to write and record a new version as part of Doctor Who's 40th anniversary. It was animated with a limited Flash animation and released on the BBC's website. This version was revised to feature Paul McGann's Eighth Doctor, along with Lalla Ward and John Leeson voicing their original characters. This version also incorporated other then-current elements of Big Finish continuity, such as Romana becoming President of Gallifrey after parting ways with the Doctor.

An extended audio version of the webcast was later released on CD by Big Finish. The original version of the webcast was also included as a DVD-ROM bonus item in the 2013 Legacy Collection DVD release of Shada.


  • No official novelisation of Shada was ever published by Target Books, as they were unable to come to an agreement with Douglas Adams that would have allowed him, or another author, to adapt the story. However, the short scene filmed for Shada subsequently used in The Five Doctors was novelised by Terrance Dicks for that story's adaptation.
  • Douglas Adams reused some of the elements of Shada in Dirk Gently's Holistic Detective Agency, notably the character of Professor Chronotis, his time-travelling apartment, and St. Cedd's college. Elements of the Doctor Who mythos not created by Adams (such as the identification of Chronotis' species as Time Lord or his time and space machine as a TARDIS) did not appear in this novel.
  • A fan novelisation was created in 1989, titled Doctor Who and Shada and written by Paul Scoones. Before the 1992 release of the story, this was the most accessible version of the narrative.
  • In early 2011, BBC Books announced that Gareth Roberts had been commissioned to write an official novelisation of Shada, for release in hardback in March 2012. Its publication follows an the agreement with the estate of Douglas Adams and was the first novelisation of a regular TV Doctor Who story since 1994.[5] This novelisation was also released as an audiobook read by Lalla Ward and John Leeson. An ebook was also released on the Amazon Kindle store.
