Planet of Fire (TV story)

Planet of Fire was the fifth serial in season 21 of Doctor Who. In addition to being the penultimate adventure to regularly feature Peter Davison as the Fifth Doctor, the story featured the final regular appearance of Mark Strickson as Vislor Turlough, the destruction of Kamelion and the introduction of Peri Brown. It was Peter Grimwade's final script and Fiona Cumming's last directorial turn for the programme. For Turlough's last story, it was decided that his mysterious past, outlined in Mawdryn Undead, should be explored.

Exteriors were shot on location in Lanzarote in the Canary Islands. The location was chosen after Cumming promoted it with photos from her holiday. Grimwade decided to use the island for multiple settings and the island's volcanic landscape also doubled for the planet Sarn. Grimwade had trouble writing for the setting, having never been there. John Nathan-Turner denied his request to accompany the select members of the crew to the island. (INFO: Planet of Fire)

Planet of Fire also had a notable guest cast: Peter Wyngarde had starred as flamboyant amateur detective Jason King in Department S and Jason King, while Barbara Shelley had appeared in various Hammer horror films.

Synopsis
A strange signal from Earth draws the TARDIS to the island of Lanzarote, where Turlough rescues a young American girl, Peri, from drowning. Among her possessions is an artefact bearing an alien symbol - the same triangular mark that Turlough has branded into his arm.

The mystery deepens when Kamelion falls under the control of a powerful mind, and the TARDIS travels to the volcanic world of Sarn. As Turlough is forced to face his past, the Fifth Doctor must stop his from harnessing the revitalising powers of Numismaton gas...

Part one
On the desolate volcanic planet Sarn, chief elder Timanov counsels the young Chosen One Malkon on how to act in the wake of increased seismic activity, heralding the imminent volcanic catastrophe known as the Time of Fire. Their god Logar, the devout Timanov warns, is greatly displeased at the number of unbelievers. As the Chosen One – so chosen due to the triangular "Mark of Logar" on his arm – Malkon has sole authority to assign heretics to burn in the Cave of Fire and thereby appease their god. Malkon doubts his resolve to condemn unbelievers to death. Meanwhile, two such unbelievers, Amyand and Roskal, scale the forbidden Mountain of Fire – believed to be Logar's dwelling place – and find the crater at the top empty. Now fully convinced that Logar is a myth, they return to the village to spread the news.

As the Fifth Doctor muses bitterly about Daleks and the departure of Tegan, Kamelion's agonised cries are heard from an adjoining room. He has linked himself to the TARDIS data core. The TARDIS then picks up a distress signal; Turlough recognises the pattern and is sufficiently dismayed that he disables the communicator to stop the signal. The TARDIS coordinates have been changed, apparently by Kamelion, and they are en route to the source of the signal, the island of Lanzarote.

American archaeologist Howard Foster and his team are trolling the nearby seabed for ancient relics. Among the artefacts they pull up is a strange, anachronistic metal object also bearing the Mark of Logar. Howard's restless stepdaughter Peri Brown, accompanying the expedition while on holiday from university, is bored and wants to travel with her friends to Morocco. Howard appears to relent but strands her on the boat to make her miss her flight. Peri is furious at Howard but finds his wallet full of money and the alien object he fished out of the lake. She thinks it may be worth some money. Peri strips to her bikini and stuffs the artefact, Howard's money and her clothes into a plastic bag. She then jumps in the sea and begins swimming to shore.

While the Doctor explores the island trying to find the source of the signal, Turlough has returned to the TARDIS, where he finds Kamelion at the console trying to establish contact with an unknown entity. Turlough overloads the console to disable him, thinking the signal may be from Trion. On the monitor, he sees Peri struggling in the water and beginning to drown. He runs out of the TARDIS, strips to his bathing suit, jumps into the water and swims out to her. He pulls her ashore and takes her to Tegan's old room to recuperate. He finds the alien artefact in the bag, pulling up his sleeve to show that he too bears the Mark of Logar on his arm. While Peri tosses and turns, muttering incoherent apologies, Kamelion seizes on her psychic impulses and transforms into Howard. The Doctor has traced the signal back to the artefact now in the TARDIS. The doors close and the TARDIS takes off automatically, apparently returning the object to its planet of origin, Sarn. Kamelion enters as Howard, but his mannerisms are like someone else's. After putting her clothes back on over her swimsuit, Peri enters the control room, confused as to where she is.

In the great hall on Sarn, Timanov and Malkon attempt to quell the citizens' unrest due to the impending Time of Fire. The arrival of Amyand and Roskal with the news of their findings causes even more disruption. A desperate Timanov calls for a sign from Logar, and a burst of flame from the Cave of Fire is the apparent answer. Timanov says this is a call from Logar to burn the unbelievers. Just then, a lookout announces the arrival of the TARDIS, describing it in a way that corresponds with their legend of the Outsider, a representative of Logar. Timanov urges Malkon to condemn the heretics, but he hesitates.

Once the Doctor and Turlough leave to explore, "Howard" announces that contact has been established and that he now has control of the TARDIS. As he laughs maniacally, his features change into those of the Master before Peri's horrified eyes.

Part two
The Doctor and Turlough explore the apparently deserted village square finding the triangular pattern, which Turlough identifies as the Misos Triangle, etched on a column. The Misos Triangle is an emblem of Turlough's home planet, Trion, but he is not forthcoming with further details. They do not notice another TARDIS materialising nearby.

The Master's control of Kamelion is tenuous, and the shape-shifting robot momentarily regains self-control. He removes the TARDIS's comparator and urges Peri to give it to the Doctor, but then loses his self-will and his form shifts back to the Master. He pulls her out into the village square towards the Master's TARDIS, but a sudden tremor knocks it over, door-side down and a large rock falls, hitting Kamelion and causing him to fall over, allowing Peri to escape into the desolate wilderness. The Master, trapped inside his TARDIS, orders Kamelion to pilot the Doctor's TARDIS inside his own, but without the comparator it won't function.

The unbelievers storm the great hall, having found and befriended the Doctor and Turlough, displaying the travellers as the Outsiders. Turlough discovers the Misos Triangle on Malkon's arm, showing his own. He is convinced that the relics in the hall are from his father's ship and that Malkon might be his younger brother. Malkon describes how he was found in the Place of Fire as an infant, and Turlough convinces him to take him there, where they find the wreckage of a crashed spaceship. They encounter Peri, who had been wandering lost since eluding "the Master". When Turlough learns that the Master is involved, they dash back to the village to warn the Doctor.

The Doctor, however, finds himself at the mercy of Timanov and his own Outsider, Kamelion/the Master. Under the "Master's" sway, Timanov orders the sacrifice of the unbelievers to the flame. "The Master" demands the return of the comparator, which the Doctor doesn't have, as his new allies are pushed toward the mouth of the Cave of Fire.

Part three
Malkon demands that the execution cease, but is shot down in the ensuing struggle. Timanov has the unbelievers and the Doctor locked into the cave with the flame. Turlough uses a Trion relic to remotely disable the sacrificial flame, which Timanov shows as a sign of displeasure from Logar at Malkon's apparent assassination. Still fooled by the "Master", Timanov leads a team in helping to shift the Master's TARDIS, but once upright, "the Master" pulls Peri inside and dematerialises. Turlough arrives and releases the Doctor and the unbelievers from the cave.

The Doctor struggles to figure out why the Master is on Sarn, and how to rescue the citizens from the impending doom of the volcanic eruption. He also reasons that the Trions had a more productive use for the Cave of Fire than mere sacrifice. Timanov speaks of a time when he was young, and he encountered Logar who took him to a bath of blue flame that rejuvenated him.

The Master's TARDIS materialises in a control room deep below the volcano. "The Master" enlists Peri's assistance, on pain of death from his Tissue Compression Eliminator weapon, in controlling the machinery there to harness the power of Numismaton Gas, which is indeed a bright blue flame renowned for its healing properties. The Doctor takes advantage of the presence of the Numismaton flame to heal the ailing Malkon in the Cave of Fire. Eluding the Kamelion/Master and ducking into the Master's TARDIS, Peri locates what she reasons must be Kamelion's control box. Lifting the lid, she finds the Master lurking within, reduced to mere inches in height.

Part four
The Master, having accidentally shrunk himself while attempting to upgrade his TCE weapon, seeks the power of the Numismaton Gas to restore himself. He constructed the control box to re-establish contact with his slave Kamelion to help him reach Sarn.

Peri accidentally knocks the Master's control box over which allows the Master to escape into his TARDIS. Peri tries to track him down and swat him with her shoe, but he escapes and hides in the TARDIS console. There, he taunts Peri and shorts the controls to open the TARDIS door. Peri runs out and into the wilderness.

The Doctor and Amyand, with Peri's help, have reached the Numismaton gas control room. They find protective metallic suits which correspond with the traditional image of Logar. The Doctor realises that the Trions have used the control room to regulate the seismic activity, but the impending eruption will be too big to control. The Doctor sends Amyand back to the ruins wearing the only remaining suit.

Kamelion pilots the Master's TARDIS into the blue flame and brings out the control box, bearing the Master within. As Kamelion advances menacingly on the Doctor with the TCE, he overloads the gas control circuitry to give Kamelion a near-fatal "heart attack". Kamelion, now freed from the Master's control, begs for destruction, and the Doctor complies with the TCE.

The Master is restored to full height by the Numismaton gas and gleefully describes the tortures that await the Doctor at his hands. But the Doctor's fiddling with the controls cuts off the gas, leaving the Master to burn in the full power of the naked flames. The Master's pleas for mercy go unheeded and the Doctor watches as his enemy is apparently consumed by fire.

Turlough, despite his status as a Trion political prisoner, swallows his pride and manages to re-activate the communication system in the wreckage of his father's ship, summoning a Trion rescue ship to pick up the Sarn survivors. Timanov, humbled by his easy manipulation by the Master in the name of his god, declines rescue and opts to perish in the ensuing volcano. Acting on instructions from the Doctor, Turlough programs the TARDIS to rescue the Doctor and Peri from the gas control room before it is destroyed. The Trion captain Lomand informs Turlough that due to a general amnesty, his exile has been lifted and he is free to return home. Turlough thanks the Doctor for everything, and the two warmly bid each other farewell. Peri, on the other hand, asks to travel with the Doctor for the remaining three months of her vacation. The Doctor agrees, and he welcomes her aboard the TARDIS as it takes flight.

Cultural references to real-world

 * Peri mentions the deities Poseidon and Hephaestus.
 * The Doctor guesses that a kouros is dated late Classical period and a work by a pupil of Praxiteles.
 * Peri hints that her mother is busy exploring a Cro-Magnon cave.

Individuals

 * Peri Brown is a young American student. She is holidaying with her mother and archaeologist stepfather, Professor Howard Foster, on Lanzarote.
 * Turlough's rank is Junior Ensign Commander. He was on the losing side in the Trion's civil war.
 * Turlough's father and his brother Malkon were exiled to Sarn, where the Trions sent occasional prisoners. Such prisoners were branded with the Misos Triangle and the indigenous population heralded them as leaders chosen by Logar, their fire god. Turlough's father died when the spacecraft crashed. The volcanic forces of Sarn were kept in check for a while by Trion scientists.
 * controls Kamelion, forcing him to control the TARDIS. The Master tries to use hypnosis through Kamelion, on Peri, in vain, partly because she has a "strong" will.
 * Peri mentions Albert Einstein.
 * Peri compares the statue of Eros to Elton John.

Locations

 * Sarn is a prison planet for political prisoners from Trion.
 * According to Turlough, the Trions have undercover agents on every civilised planet, and cites as examples an agrarian commissioner on Verdon, a tax inspector on Darvey, and a very eccentric solicitor in Chancery Lane.
 * Turlough defines the Brendon Public School as the "worst place in the universe".
 * Peri meant to move to Morocco for a while.
 * At the bar, the Doctor pays with an unknown kind of coin, not accepted in Lanzarote.
 * Peri's return flight is to New York.

Science

 * Peri's summer studying includes an ecology project.
 * The volcanic activity on Sarn produces Numismaton Gas, "an immensely rare catalytic reagent" with great healing properties.

The TARDIS

 * Kamelion is endangered when he is connected to the TARDIS databank.
 * The Master removes the temporal stabiliser from the Doctor's TARDIS, rendering it inoperable. Kamelion removes the comparator, another vital circuit.
 * The TARDIS is provided with a seismic scanner.
 * Turlough sets the TARDIS on a time-delayed takeoff.
 * Peri compares the Master's TARDIS to the Doctor's own TARDIS. The Master claims his TARDIS is "infinitely superior".

Technology

 * The Master accidentally shrank himself while adjusting his Tissue Compression Eliminator.
 * Peri finds and uses a telescope on the slope of the volcano.

Story notes

 * This story had the working title of Planet of Fear.
 * Kamelion appears for the first time since The King's Demons the previous season; complications involving the robot model prevented him from appearing in other episodes, although a scene was filmed for The Awakening but edited out before transmission. Kamelion's "death" makes him the fourth known companion to die while travelling with the Doctor, following Katarina, Sara Kingdom, and Adric.
 * It was during the production of this serial that Peter Davison and Nicola Bryant participated in their infamous "James Bond" photo shoot, in which Davison donned a tuxedo and prop gun and Bryant a bikini.
 * There are parallels with the novel, whose title character renews herself periodically by bathing in a magic flame. Haggard's great-great-great-niece Daisy Haggard would later play Sophie in TV: The Lodger and Closing Time.
 * This is the only televised Fifth Doctor story not to visually contain Tegan Jovanka. The Doctor's reference to Tegan at the beginning of part one means that she was technically a part of every single one of his television stories in some way. To date, the only other companion to have been a part of every televised story of a given Doctor is Rose Tyler, who appeared in every episode during the Ninth Doctor era.
 * This was the final serial to feature a male companion until the series revival in 2005. Turlough was the last male companion seen on screen — barring the return of Alistair Gordon Lethbridge-Stewart in TV: Battlefield in 1989 — until Adam Mitchell appeared in the two stories TV: Dalek and TV: The Long Game in 2005. However, there were several non-televised male companions to have travelled with the Doctor in other media between Turlough and Adam, including Frobisher, Thomas Brewster, Hex and C'rizz.
 * The departure of Turlough and the destruction of Kamelion mark the end of an almost seven-year span of stories featuring at least one non-human companion. It began with the introduction of the robot dog K9 Mark I in TV: The Invisible Enemy in 1977. The other non-human companions who travelled with the Doctor in the interim were K9 Mark II, the first and second incarnations of the Time Lady Romana, the Alzarian Adric and the Trakenite Nyssa. Turlough and Kamelion would be the final non-human companions to appear in a televised Doctor Who story, until the guest reappearance of K9 Mark III in TV: School Reunion in 2006. Turlough would also be the last non-human companion and last male companion to travel alone with the Doctor until Nardole became a companion in TV: The Return of Doctor Mysterio.
 * The Radio Times incorrectly credits Nicola Bryant as "Perpugillian Brown" and Gerald Flood as "Voice of Kamelior".
 * The Master's final line before apparently being killed is directed squarely at the Doctor: "Won't you show mercy to your own ..." According to the DVD commentary, Fiona Cumming asked John Nathan-Turner how the line was to end, to which he replied, "brother". However, Anthony Ainley never said the word in any take captured on video. Thus fans were free to speculate about how the line was to have ended. In TV: The Sound of Drums, the Tenth Doctor strongly implies that the Master was not his brother.
 * In PROSE: Shell Shock, it is strongly implied that Howard sexually abused Peri when she was younger. Some read this as supporting Peri's dream-state behaviour in this story where she shouts out Howard's name after saying, "Don't turn out the light." However, by concentrating on just these two lines, the two previous lines —"No, Howard. Please don't leave me alone." — are conveniently ignored. It's somewhat unlikely that a person plagued by parental abuse would be begging for the abuser to stay with her. Indeed, the DVD commentary makes it very clear the production team were aiming for a positive, friendly relationship between the two characters and there's not much more than Shell Shock which suggests anything improper between Howard and Peri. In fact, AUDIO: The Reaping details the reasons for the divorce of Howard and Peri's mother Janine Foster and completely fails to mention any sort of sexual abuse. Shell Shock is thus one view of the relationship between Peri and Howard, which has never been supported clearly by any performed Doctor Who.
 * The story was the second of three consecutive serials, along with Resurrection of the Daleks and The Caves of Androzani, that saw the departure of one of the season's regular cast members. In this serial, Mark Strickson departs as Turlough.
 * Peter Grimwade was furious at the casting of Dallas Adams as Prof. Foster. He had written the part for an elderly man and this casting caused Grimwade to cut his links with the series.
 * The Master was originally supposed to be killed off for good, as Anthony Ainley's contract had expired.
 * Graeme Harper was attached to direct at one time. He ended up directing the following story instead.
 * The script originally contained commentary on issues of religious zealotry, something that was toned down by Eric Saward.
 * In the script, Peri forged a bond with the Doctor in part because he reminds her of her late father, who died at the same age as the Doctor now appears.
 * The Elder leader Timanov was written originally by Grimwade as a parody of Iran's Ayatollah Khomeini but this element was greatly reduced in rewrites by Eric Saward.
 * It was decided that because of the climate of Lanzarote, where the serial was filmed, the cast would have to alter their usual costumes. Although Peter Davison started the story wearing his cricketer outfit, for the rest of the story, he wore a different pair of trousers with question mark braces and a beige floral waistcoat. Mark Strickson shed his usual school uniform in favour of a blue pin-stripe shirt and tan shorts with a pair of swim briefs underneath. Nicola Bryant also wore a pink bikini beneath her clothes to which she stripped down for a couple of scenes.
 * Peter Davison later said that his look of sorrow and remorse at having to kill Kamellion was pure acting, as he was genuinely glad to be rid of the troublesome prop.
 * Filming the scene where Turlough rescues Peri was bizarrely disrupted by a German nudist, who believed that Nicola Bryant was actually drowning when she filmed the scene of Peri in the water. The man was very unhappy to learn that Bryant was just acting, and later ruined a take for a scene on the beach when he ran through the shot.
 * On the last night in Lanzarote, Dallas Adams and Peter Wyngarde liberated some turtles kept in the hotel pool and released them into the sea, causing the police to be summoned.
 * John Nathan-Turner got the idea to use Lanzarote as a setting when Fiona Cumming went there on holiday and sent him a postcard.
 * Peter Grimwade was chosen to write the script to compensate him losing the job directing Resurrection of the Daleks. Eric Saward felt he'd paid his dues to Grimwade, but felt that the script didn't work and it wasn't worth it in the end.
 * Kamelion morphs into the Master and Howard in order to avoid having to bring the cumbersome robot prop on location.
 * Peter Grimwade decided that Lanzarote would feature as two different locations in the story -- the Greek island of Aeschyllos and the alien planet Sarn -- to take advantage of the variety offered by the landscape. Grimwade was subsequently informed that the deal worked out between the production office and the Lanzarote Tourist Board meant that the Earthbound sections would actually have to be set in Lanzarote itself, forcing him to abandon some of the historical detail he had worked out. Grimwade found that writing for the Lanzarote locale was very difficult because of his unfamiliarity with the island. He had hoped to join the production team on a recce to Lanzarote in September, but was disappointed when John Nathan-Turner denied his request.
 * Peter Grimwade later said that the comission "was just an excuse for the producer to take his team on a gang-bang and a nice holiday. It didn't work at all. You don't just comission a story and set it in Lanzarote because you want a bloody holiday".

Production errors

 * The studio and location shots of Turlough rescuing Peri don't quite match up. She's still wet from her near-drowning when Turlough gets her to the exterior of the TARDIS doors, but is dry when they cut to the interior, studio shot.
 * According to director Fiona Cumming in the DVD commentary, Peri's passport was not specifically made for this production, but was, rather, the reuse of a passport that actor Dallas Adams had used in another production. Therefore, any details gleaned from freeze-framing the close-ups on the prop — such as her birth date and location — were not specific to Peri, but to the character Adams had played in the other production. Thus, they are technically production errors. Oddly, the production subtitles on the DVD champion the information contained within the passport, despite Cumming's revelations about the true origin of the prop.
