The Mysterious Planet (TV story)

From Tardis Wiki, the free Doctor Who reference

The Mysterious Planet was the unbroadcast title given to the first story of The Trial of a Time Lord, the season-long story arc that constituted season 23 of Doctor Who. The story marked the first appearance of the Inquisitor and the Valeyard, two characters who would appear throughout the season, along with Sabalom Glitz, who would appear again later in the season and also in season 24. With this story, the series returned to half-hour episodes. Also beginning with this story, the series was now completely produced on videotape (with the exception, in this story, of a brief special effects sequence in Episode 1).

With this episode, Peter Howell's rendition of the Doctor Who theme was exchanged for a mysterious and surreal arrangement of the theme tune composed by Dominic Glynn. It would remain in use solely for season 23 and close out Colin Baker's era on the series.

BBC executive Jonathan Powell was notably harsh when given the scripts to view, citing all his concerns in a memo to John Nathan-Turner and Eric Saward. Such a negative reaction stunned Nathan-Turner and Saward; Saward was especially rattled as he had held Robert Holmes in high esteem in the past and hadn't queried the scripts as they came in. This was perhaps the moment that Saward began questioning his own self-belief in the series and doubting his abilities as a script editor. This would later lead to his departure a few months later.

This story also introduced some costume changes for the Doctor and Peri. The Sixth Doctor entered his second full season with a red check vest & cravat and a bright pink watch chain. To help viewers discern between scenes taking place in different points in the Doctor's timeline, scenes set in his past feature him donning his original turquoise cravat & neon green watch chain for the last time; the following story would feature the Doctor's full new outfit in both past and present scenes, and the one after that featured a completely different vest & cravat for the archival scenes, which are set in the Doctor's future.

Notably, Nicola Bryant's character Peri Brown starts wearing more conservative clothing from here out, after spending most of her appearances in loose-fitting and often revealing outfits. Her wardrobe change was a result of complaints that her provocative clothes were inappropriate for younger Doctor Who viewers.

Synopsis[[edit] | [edit source]]

The Doctor is summoned before the High Council of Time Lords to stand trial for the charges of harmful interference to the course of events during his space-time excursions, which have threatened the sanctity of the universe. Indignant at these accusations, the Doctor pleads his case to the Inquisitor with the hope that she will see him as a source of hope and goodwill for existence. However, his prosecuting attorney, a sinister Time Lord known simply as the Valeyard, begins a crusade against the Doctor's life with the motive of painting him out to be a villainous renegade.

The Valeyard's first movement against the Doctor is to review his past interactions on a familiar planet called Ravolox, where he and his-then companion Peri Brown met the morally grey Sabalom Glitz and a tyrannical robot stalking the world's desolated landscape. However, Ravolox holds a terrible truth in the far reaches of its ruins, while the Doctor's trial has its own fair share of startling twists and turns...

Plot[[edit] | [edit source]]

Part one[[edit] | [edit source]]

The TARDIS materialises in a corridor, and the Sixth Doctor emerges, bewildered and alone. He walks into a room, where he is put on trial for conduct unbecoming a Time Lord. The Inquisitor notes that the Doctor has been on trial previously. The Valeyard states he will argue that the Doctor was shown too much leniency on that occasion. The Valeyard opens the case by using the Matrix to show the Doctor's actions on the planet Ravolox.

The Doctor and Peri arrive on Ravolox, which is virtually identical to Earth. He tells Peri that the official records state that the planet was devastated by a fireball, but the forest they are walking through suggests otherwise. They are seen by Sabalom Glitz and Dibber, who attempt to shoot the Doctor. He moves off just in time. Glitz and Dibber discuss their plan to destroy the "L3 robot" by sabotaging its light conversion system, which has been turned into a totem by a primitive tribe.

The Doctor and Peri explore a cavern. Peri discovers a sign saying "Marble Arch" — a London Underground sign. This means that they are on Earth. Peri begins to mourn for her planet.

The Doctor interrupts the replay to ask what the relevance of this is. He then also asks why Peri is not with him on the station. The Valeyard answers that she is where the Doctor left her and states that the Doctor's evident temporary amnesia — a side-effect of being taken out of time — should soon pass.

As the Matrix resumes showing the events on Ravalox, Peri is still upset. The Doctor goes into the complex alone. Two masked figures appear and capture Peri. Meanwhile, Glitz and Dibber are brought before Katryca, Queen of the Tribe of the Free. Glitz claims that the totem attracted the fireball that devastated Ravolox and asks for it to be taken down. The Queen tells him that others have asked for the totem to be dismantled, and none have succeeded. Glitz and Dibber draw their guns but are overpowered and locked up.

The Doctor finds an underground complex and picks up a bottle of water. This sets off an alarm, and people enter and subdue him. He is accused of stealing water and sentenced to be stoned. The Doctor tries to block the rocks with his umbrella but is knocked unconscious.

The Valeyard proposes that the inquiry into the Doctor's activities should become a full-blown trial, with the penalty being the termination of his life...

Part two[[edit] | [edit source]]

Other officials arrive and break up the stoning. The Doctor is still breathing. Before he can be killed, Merdeen receives a message from the Immortal stating that he wishes to question the Doctor. The Immortal is revealed to be a huge humanoid robot, commands its two assistants to release the service robot.

Peri is brought before Katryca, who informs her that as there are few women, she will need to take many husbands as a member of her tribe. She is put in the same prison as Glitz and Dibber. They tell Peri their plan to destroy the robot. They are taken back to Katryca, who tells them that Glitz will be sacrificed because of his attempt to destroy the great totem.

The Doctor is taken to the Immortal, who introduces itself as Drathro. It commands the Doctor to work with the two assistants. The Doctor identifies the problem and tries to leave in order to fix it, but Drathro does not allow him to, as his instructions are to maintain an underground system. The Doctor electrifies the robot and his assistants and escapes. Drathro sends the service robot to track down the Doctor. Meanwhile, Peri, Glitz and Dibber overpower the guards and escape. Dibber remains behind to plant a bomb on the black light converter, whilst they go to the underground complex.

In the Marb Station, Merdeen tells Balazar that there has been no fire for hundreds of years, and he should leave the complex. They encounter the Doctor, and Merdeen implores him to help Balazar escape. Peri, Glitz and Dibber, pursued by tribesmen, find the Doctor, and they flee into the Marb Station but are trapped between the tribe and the service robot. When Peri asks what they should do, the Doctor replies, "I don't know. I really think this could be the end. . . "

Part three[[edit] | [edit source]]

The Doctor and Peri are saved when the tribesmen shoot at the service robot and disable it. The Doctor tries to re-enter the underground complex, but the tribesmen insist they all return to the village. There, the Doctor is brought before Katryca. She is unimpressed with his explanation of the true nature of the totem and puts them all back in the prison cell.

Glitz confirms that the planet is actually Earth. Drathro reactivates the service robot and sends it to the village. It breaks into the building with the Doctor, stuns him after an attempted handshake and takes him away. The tribesmen disable the service robot and decide to attack the Immortal's castle to steal his technology, believing that they have killed him. Peri rescues the Doctor from the service robot. They set off to the underground complex to stop Katryca and disable the black light system.

Removed evidence.

The Doctor and Peri encounter Merdeen in the corridors of the underground complex. He tells them that he is hunting. When the Doctor asks who his quarry is, he looks at the Doctor and says, "You". He raises a crossbow weapon at the Doctor and fires...

Part four[[edit] | [edit source]]

Katryca and the tribesmen arrive at the castle, where they are confronted by Drathro. He electrocutes Katryca and dismisses the rest of the tribe. The Doctor enters Drathro's domain, promising to help repair the black light system. However, he determines it to be beyond repair and tells Drathro that he must shut down the black light system to prevent a massive explosion. Drathro refuses as it would mean its own destruction. The Doctor pleads with him, saying that the explosion could destroy the entire universe. That makes Drathro determined to allow what he thinks is a unique event.

Glitz tells Dibber that "five rounds rapid" ought to disintegrate the door.

Balazar and Peri plead with Merdeen to help them, noting that he would die if the converter exploded. Glitz and Dibber arrive and follow them into the castle through a food chute. Drathro tries to kill them by turning on the food processing system, but Dibber shoots him through the wall. Glitz tells Drathro that they have black light on their ship, and offers to take the robot to the Andromeda Galaxy. Drathro agrees and leaves with Glitz and Dibber.

The Doctor realises that the black light system has already begun to self-destruct. All he can do is prevent it starting a chain reaction. The system explodes, but the blast only destroys the castle, and as a result, Drathro collapses. The Doctor and Peri leave Merdeen and Balazar to take the remaining inhabitants to a new life on the surface.

The Doctor announces to the court that he has saved the Universe, and starts to present his defence. The Valeyard warns the Doctor that he has more evidence to come and that the court will demand the Doctor's life at the end...

  • When the Doctor is forbidden to look upon the Immortal, he jokes about the risk of being turned into a pillar of salt.
  • A hint of identity between Ravolox and Earth is the presence of the Marble Arch station in the underground.

Individuals[[edit] | [edit source]]

Earth[[edit] | [edit source]]

The Doctor[[edit] | [edit source]]

  • Black light is not the Doctor's field.
  • The Doctor has been deposed as Lord President of Gallifrey for neglecting his duties.
  • The Doctor doesn't believe in ghosts.
  • The Doctor seems about to state his name casually to Peri but is interrupted.
  • The Doctor is called "Old One" by Balazar.
  • The Doctor seems to suffer amnesia because of having been taken out of time.

The Doctor's items[[edit] | [edit source]]

  • In his pockets, the Doctor carries a torch, an oil can, a paper mask, a teddy bear, and a bag of sweets.
  • As Tandrell and Humker rummage through the Doctor's coat pockets, they discover a bag of jelly babies, which the Doctor quickly snatches back before offering each one of the sweets.

Law and order[[edit] | [edit source]]

Mythology[[edit] | [edit source]]

  • The Free worship the Earth god Haldren. The black light converter functions as its totem.

Substances[[edit] | [edit source]]

  • According to Glitz, silictone (a material the light converter is made of) is the most expensive metal in the galaxy.

Technology[[edit] | [edit source]]

Time Lords[[edit] | [edit source]]

  • The Doctor is under process because of the infringement of the First Law.
  • The trial takes place on a Time Lord space station.
  • The Valeyard thinks that the High Council were "too lenient", with regards to the Doctor's previous trial and reduction in sentence.
  • The evidence is shown from images taken from the Matrix, the repository of all knowledge.
  • When recovering from the service robot's attack, the Doctor briefly refers to Peri as "Sarah Jane," and speaks in the mannerisms of his third incarnation.
  • TARDISes now have the means to upload information into the Matrix through their sensors, even if the Time Lord pilot is underground, or if the pilot is nowhere near another location. The Doctor's TARDIS, despite its status as a Type 40, now has this facility, making the Doctor accuse the Time Lords of 'bugging' his TARDIS.
  • The Doctor entered the trial room propelled by the mental energy of the distinguished Time Lords on the stand.

Story notes[[edit] | [edit source]]

  • Working titles for this story were Wasteland and The Robots of Ravalox.
  • Despite the change to the 'Doctor Who Theme' arrangement, the title sequence introduced in The Twin Dilemma remained unchanged for the season.
  • Beginning with this story, Doctor Who returned to its original 25-minute episode format, which it retained for the remainder of the original series. However, the total length of the broadcast season remained fixed at about three months annually, resulting in about a 50% drop in seasonal output as compared with previous seasons.
  • In an interview in Doctor Who Magazine 448, Timelash author Glen McCoy said that he came up with the idea of the Doctor being put on trial.
  • Beginning with this story, all exteriors would be recorded using Outside Broadcast video, rather than film as had usually been the practice for the previous 22 years. The use of OB for exteriors would continue for the remainder of the original series, until its end in 1989.
  • The filmed insert that begins part one of a special effects sequence involving the TARDIS and the space station would be the last shot-on-film footage made for Doctor Who until the 1996 TV movie. Ironically, the Fox network recycled this footage for its promotional advertisements for the film (even though it wasn't included in the movie). The series revival from 2005 to the present uses videotape which is later processed to look like film, though small parts have been shot on film.
  • The model of the space station was six feet wide. The 45-second-long opening scene of it from this story was the first use of a motion-control camera on Doctor Who, took a week to film, and cost over £8,000 making it the most expensive Doctor Who sequence to date. John Nathan-Turner justified the sequence's cost as it was the first new scene shown to viewers after the programme's hiatus, and by reusing parts of it as establishing shots for the rest of the Trial stories. [1] Colin Baker felt that the money could have spent elsewhere.
  • The Radio Times programme listing for part one was accompanied by a black-and-white publicity still of the Inquisitor and the Doctor in the courtroom, with the accompanying caption "Can the Doctor (Colin Baker) convince the Inquisitor (Lynda Bellingham) that he hasn't been misusing his time? / BBC1, 5.45 p.m. Doctor Who". (original published text)
  • In a featurette included with the 2008 DVD release, Nicola Bryant states that "some time has passed" since the events of Revelation of the Daleks, and therefore she and Baker played their roles as if the two had grown closer over time. Exactly how much time passed for the characters during the show's 18-month hiatus has never been established. The Doctor in this story states he is 900 years old, the same age given in Revelation; however in an episode of The Ultimate Foe, Mel states the Doctor's age as "900-odd" suggesting this is an approximation or it reflects the fact the Doctor meets Mel at a later time than he does Peri.
  • Sabalom Glitz returns in numerous stories, often shown collaborating with the Doctor. For this reason, he is sometimes referred to as a companion, though there is no indication that he was ever officially considered such by the BBC, although the question of who "counts" as a companion is notorious finicky.
  • Graeme Harper was asked to direct, but was not free.
  • In AUDIO: The Dark Flame it is explained what exactly "black light" is. It is not ordinary ultraviolet light, but energy from quantum meta-fluctuations in the space/time continuum.
  • The Doctor says he is 900 years old, as in TV: Revelation of the Daleks. However, this is at odds with the ages given by the War Doctor and Ninth Doctor in later adventures. (See The Doctor's age)
  • The fourth episode overran, so to compensate, several segments were removed or trimmed, including some material from the courtroom. This included what should have been the second trial scene, in which the Valeyard observes the Doctor revealing confidential Gallifreyan information to Peri and the Inquisitor asks the Doctor why he visited Ravolox in the first place. A later loss was the Valeyard's pronouncement that Humker and Tandrell would have repaired the system problem themselves were it not for the Doctor's interference, and the Doctor noting that the situation on Ravolox had endangered the entire universe.
  • Joan Sims is said to have disliked her stint on the series.
  • Tom Adams, Keith Barron, Hywel Bennett, Brian Blessed, Andrew Burt, Kenneth Colley, Peter Gilmore, Michael Gothard, Bernard Hill, Gareth Hunt, Paul Jerricho, Clive Merrison, Paul Shelley, Anthony Valentine, Peter Vaughan, David Warner and James Warwick were considered for the role of Merdeen.
  • Lynda Baron, Honor Blackman, Isla Blair, Jill Bennett, Brenda Bruce, Adrienne Corri, Sheila Hancock, Janet Henfrey, Eartha Kitt, Rosemary Leach, Jean Marsh, Siân Phillips, Dinah Sheridan, Elizabeth Spriggs, Wanda Ventham and Fiona Walker were considered for the role of Katcyra.
  • Brian Blessed, James Bolam, Roger Daltrey, Michael Gothard, Del Henney, Gareth Hunt, Alfred Lynch and John Thaw were considered for the role of Glitz.
  • Nicholas Mallett considered casting Dawn French and Jennifer Saunders as Glitz and Dibber, but they weren't available.
  • Colin Baker admitted that the script wasn't the greatest and didn't like the "junkyard, railyard" remarks, either.
  • Roger Brierley was originally supposed to deliver his lines as Drathro while inhabiting the robot costume constructed by the BBC Visual Effects Department. However, he found the outfit claustrophobic and unwieldy, and he soon became adamant that his involvement be limited to providing Drathro's dialogue. John Nathan-Turner initially believed that the role would have to be recast at short notice, but visual effects designer Mike Kelt had anticipated this development. Instead it was agreed that Kelt's assistant, Paul McGuinness, would operate Drathro, while Brierley read in his lines from off camera.
  • Colin Baker, Tony Selby and Joan Sims had pudding eating competitions. Baker won after the other two gave in after three.
  • Tony Selby described Glitz as "Arthur Daley in space".
  • When Nicholas Mallett alerted John Nathan-Turner to his concern that the final two episodes were badly underrunning, he extended some of the courtroom material, and also composed an extra scene in which Broken Tooth and Balazar argue about the route to the “castle”.
  • Jonathan Powell hated the story. In an unusually detailed commentary, he took issue with the slow reveal of the trial scenario, the lack of clarity as to the nature of the crisis on Ravolox, and the extent of the Doctor's involvement in its resolution. Most frustratingly for John Nathan-Turner, Powell seemed to contradict Michael Grade's edict that humour feature more prominently in Season 23, reserving some of his most stinging criticism for elements such as the Doctor's taunting of the Valeyard and the comic banter between Glitz and Dibber. Robert Holmes was deeply hurt by these criticisms and Eric Saward was angry at Powell's lack of respect for Holmes. Fortunately, John Nathan-Turner and Nicholas Mallett were able to convince Powell that only fairly minimal changes to Holmes' scripts were necessary. This included the deletion of an early scene depicting the Doctor and Peri in the TARDIS, which made way for the Doctor's earlier discovery of the nature of his trial, and the elimination of much of the invented slang from Glitz and Dibber's dialogue.
  • Robert Holmes was in ill-health when he wrote the script. Eric Saward thought that he could write good dialogue.
  • At one stage, Drathro was joined by another L3 robot called Jethro who had been severely damaged. This character was later replaced by Humker, Tandrell and the L1 service robot.
  • Robert Holmes rehashed the plot of his first serial The Krotons, while the banter between conmen was lifted from The Ribos Operation.
  • Nicholas Mallett informed John Nathan-Turner that episodes three and four were badly underrunning. With Robert Holmes too sick to contribute the necessary material, Nathan-Turner himself wrote two and a half minutes' worth of content, extending some of the courtroom material while adding an extra scene in which Broken Tooth and Balazar argued about the route to Drathro's “castle”.
  • When the cast and crew arrived in the studio to film the trial scenes, the courtroom set was nowhere to be found. It transpired that it had been erected in the wrong studio and, when hurried attempts were made to assemble it, it was found to be too large and in need of modification. As a result of these delays, Nicholas Mallett was unable to record the Doctor's arrival on the space station, so it had to be remounted.
  • John Nathan-Turner cast Lynda Bellingham and Tony Selby, having met them at the restaurant owned by Bellingham's husband.

Myths[[edit] | [edit source]]

  • The unnamed character, "the Inquisitor", is Flavia, last seen in The Five Doctors and presumably regenerated. This question remains unanswered in terms of televised episodes. Spin-off works, however, give her a different name, Darkel.
  • While shooting publicity photographs for the Trial season, and also when doing television interviews promoting the season, Colin Baker sported a beard; this led to the mistaken assumption by media and fans that the Doctor would be bearded during this and the other stories.
  • Rumours indicated that the Doctor's name would be revealed. The Doctor seems about to state his name rather casually to Peri while musing about a paper he wanted to write, but he is interrupted just before he says his name or an alias he wished to use for the book.

Filming locations[[edit] | [edit source]]

  • Queen Elizabeth Country Park, Gravel Hill, Horndean, Hampshire
