Destiny of the Daleks (TV story)

Destiny of the Daleks was the first serial of season 17 of Doctor Who. It was written by Terry Nation, directed by Ken Grieve and featured Tom Baker as the Fourth Doctor and John Leeson and Roy Skelton as K9 and introduced Lalla Ward as Romana II

It was the first story to feature Ward as Romana, though only the third produced. However, The Lying Old Witch in the Wardrobe would later reveal that the Romana in this serial was The Doctor's TARDIS masquerading as her, and that she was actually trapped in the TARDIS wardrobe room for the duration of this serial.

It also featured the twelfth appearance of the Daleks and the second appearance of Davros, portrayed by David Gooderson for the only time. It was the final televised story to be written by Terry Nation, who had contributed scripts since 1963. It was the first story produced under the auspices of script editor Douglas Adams.

This was also Romana's first and only televised story with the Daleks, though the expanded universe establishes this not to be her first chronological meeting with them.

Notably, part one saw K9 being voiced by Dalek voice actor Roy Skelton. This was because K9 had contracted laryngitis and all that was needed of him was a croaking sound.

Synopsis
The Doctor and a newly-regenerated Romana arrive on Skaro to find that the Daleks are using explosive charges and a group of humanoid slave workers to mine the planet in search of their creator, Davros. A stalemate has arisen in an interplanetary war that the Daleks are waging against the robotic Movellans, and their hope is that Davros will be able to give them the edge.

A force of Movellans has also arrived on Skaro, determined to thwart the Daleks' plan. Davros is found in the ruins of the old Kaled city and immediately revives, his life support systems having held him in suspended animation since his apparent death. He quickly deduces that the battle computers of the two warring races are locked in a logical stalemate and that he can break this by introducing an element of intuition.

The Movellans, having reached the same conclusion, want the Doctor to do likewise for them. Davros attempts to destroy the Movellan ship using a suicide squad of Daleks loaded with bombs, but the Doctor returns to the Kaled city and tricks him into inadvertently detonating them before they reach their target.

The Movellans are deactivated and Davros is cryogenically frozen on board their ship until the freed slave workers can take him to Earth and ensure that he is put on trial for his crimes.

Episode 1
The Doctor has installed a "randomiser" on the TARDIS to elude the Black Guardian. While he is repairing K9, the Doctor marvels at K9's impressive and complex electronic "brain". He notices that K9 is, unusually for a robot, coughing. He establishes that K9 has a form of laryngitis (which is, as the Doctor points out, pointless, as a robot would have no use for such an affliction). He calls for Romana, and is surprised when Princess Astra from the preceding adventure emerges (in full regal regalia). However this is not Astra at all: it is Romana, and she has regenerated into a form which she has modelled on the princess. The Doctor is not impressed and tries to dissuade her from "going around wearing copies of bodies". He urges Romana to try another body. She agrees and walks out of sight to do just that. When she returns she is a dwarfish, purple-faced female, who retains Romana's voice. Unhappy with the height, she is told by the Doctor to "lengthen it", and she leaves to try again. When she returns, she resembles a drag queen; the Doctor (possibly slightly disturbed by this) gives a polite, "No thank you, not today." Romana then tries an extremely tall, willowy and serious-looking female form, which the Doctor dismisses as being too tall. He advises her to wear something more sensible and stylish, and she returns in an outfit resembling his own. He is delighted, until he realises that she again resembles Astra, only in different clothing. He gives up, realising that her mind is made up, and agrees to let her resemble Astra. The TARDIS then lands... The TARDIS has landed on a very rocky planet which has breathable air and hospitable conditions, but has dangerously high levels of radioactivity. The Doctor gives Romana tablets to combat the radiation and a beeper-like device to inform her when she must take her pills. They exit the TARDIS and establish that this rocky planet has seismic disturbances. They witness what appear to be ragged-looking natives burying one of their dead. On closer inspection, they find that this deceased fellow is not what they thought: he is from the planet Kantra, a tropical paradise. How he came to be on this rocky planet is a mystery. They see a spaceship land, and find that it has half-buried itself into the ground in a valley. Just as the Doctor and Romana are about to investigate, underground explosions force them towards the ruins. While they explore, a column falls upon the Doctor. It is too heavy for Romana to lift alone. She agrees to reassemble the literally "brainless" K9 and get him to assist in removing the debris. She sets off, but finds the TARDIS half-buried in rubble. Unbeknownst to her, she is being followed. Realising that she cannot reach K9, Romana turns back.

Meanwhile, the Doctor is quite happily reading a book (Origins of the Universe by Oolon Colluphid), and remarks that he needs to remind Romana to take her anti-radiation pills. A troupe of silver-haired humanoids appear and point their weapons at him. He attempts to charm them, but it does not seem to work. Meanwhile, Romana returns to the ruin. The Doctor has vanished. As she turns to leave, she finds the man who has been following her blocking her path. She backs away, only to fall down a rubble chute, losing consciousness. The man prepares to climb down and help her.

The Doctor (unharmed) is with the Movellans, as these silver-haired humanoids are called. He thanks them for helping him, and remarks at their strength. He asks their commander, Sharrel, what planet they are on, and is told that it is known as D-5-Gamma-Z-Alpha. The Doctor enquires to its name, and is astonished to hear that the answer is Skaro.

Before the old man has climbed down after her, Romana recovers consciousness and hears a drilling noise coming from one of the walls. The wall seems to be moving. She backs away from the wall. Suddenly a pair of Daleks burst through it: "Do not move. Do not move. Do not move. Do not move. Do not move. Do not move. You are our prisoner – do not move. You are our prisoner!"

Episode 2
The Daleks threaten to exterminate Romana if she does not comply with their instructions explicitly, and then command Romana to come with them. The man, meanwhile, has seen the whole thing. The Movellans tell the Doctor that they are on Skaro to wage war against the Daleks. Meanwhile, Romana is being interrogated by the Daleks. After determining that she is no threat to them, the Daleks command Romana to work at one of their drilling sites.

The Doctor and the Movellans meet with the man who has been following Romana and him. He identifies himself as Starship Engineer Tyssan, captured by the Daleks two years ago. He collapses after revealing that the Daleks have used him as slave labour for drilling as part of a search operation. He soon comes around, and says he does not know what the Daleks are looking for. He tells the Doctor about what has happened to Romana, and they set out to rescue her.

In the meantime Romana meets with other workers, with whom she discusses the Daleks' hatred for humanoids. She learns that she is getting weaker as a result of radiation sickness, and is told that the only way out of captivity is to die. Within minutes, she collapses and seems to die. Her fellow workers remove her body.

The Doctor, Tyssan and the Movellans Sharrel, Lan, and Agella are shocked to find Romana's grave. As the Doctor frantically tries to dig her out, Romana appears and explains that she feigned death in order to escape. At school she had been taught how to stop her hearts. They head to the Dalek headquarters. Lan is left on guard outside of the Control Centre, and is shot down by a Dalek who is out searching for them. The Doctor establishes that the Daleks are searching for something on a level that they have yet to access. He remembers an alternative route to this area, so he, Romana, and Agella make their way to this floor while Sharrel returns to his ship. They discover Davros, the creator of the Daleks, who had seemingly been exterminated when the Doctor last saw him. (TV: Genesis of the Daleks). Something gives way up above, and part of the ceiling collapses on Agella. While the party is distracted by this, Davros starts to stir: his fingers move, his central artificial eye lights up – and Davros awakens...

Episode 3
"The resurrection has come, as I always knew it would", says the awakened Davros. The Doctor finds Davros and takes him into a blocked-off room in the old Dalek city. He lets Romana and Tyssan escape out the window, and they return to the Movellan ship. The two geniuses talk about the Daleks' "accomplishments"; whilst the Doctor comments on the countless lives the Daleks have ruined, Davros replies that this is only the beginning – the Daleks have only just begun their conquest of the cosmos. The Daleks find them and proceed to exterminate their prisoners until the Doctor complies. The Doctor threatens to kill Davros with a makeshift explosive he has just concocted. He orders the Daleks to free all their prisoners, and to let him escape. The Daleks say that these conditions are unacceptable and illogical - and therefore, to a Dalek, impossible. The exterminations will continue. Davros makes them see that the Doctor's logic is "impaired by irrational sentiment". The Daleks now comply. The Doctor attaches the explosive to Davros' chair, and tells him that it will detonate when he uses his sonic screwdriver. He escapes. Davros frantically orders the Daleks to remove the explosive, which they do. The Doctor detonates the explosive remotely, and the explosion seems to take a Dalek with it. Davros vows to make the Daleks invincible, and the supreme power of the Universe. Unbeknownst to them, Agella is not dead. She returns and reports all she has just heard to her fellow Movellans.

Romana reaches the Movellan spaceship, but learns that the Movellans are not as altruistic as they appear. Agella uses her weapon on her and knocks her out. The Movellans test out their nova device, a weapon which changes air molecules so a planet's atmosphere becomes flammable and can be set alight – killing all lifeforms.

The Doctor meets up with Tyssan and they find a Movellan scout. The Doctor deactivates her by removing the power pack/controlling circuit on her belt and reveals that the Movellans are, in fact, robots. He finds that the unconscious Romana has been attached to the nova device, sealed inside an airtight container. He sends Tyssan away and tries to open the container, as the timer is ticking down...

Episode 4
As the timer approaches zero, the Doctor is knocked out by one of the Movellans' weapons. However, the nova device was revealed to be a "dud" – a decoy used to lure the Doctor.

The Doctor learns that the Daleks and Movellans have been in a stalemate for over two centuries, and that both sides' battle computers have been calculating the best strategy and precise moment at which to attack – so far not a single shot has been fired. The Daleks want Davros to help them gain an advantage. The Movellans want the Doctor to do the same for them, which the Doctor refuses to do. Davros, on the other hand, is eager to give the Daleks the upper hand; he orders them to make a suicide bombing attack on the Movellan craft on realising that the Doctor might do the same thing for the Movellans. The Doctor leads an attack by the slaves on the Movellans, which ends with them all being deactivated.

While the prisoners take control of the Movellan ship, the Doctor makes his way to the city to confront Davros. He tells Davros that the Movellans have been disabled; unfortunately Davros does not believe him and intends to destroy the Movellan ship anyway. As the Daleks approach the ship, the Doctor goes to detonate the bombs prematurely, only to discover too late that Davros didn't send all the Daleks on the suicide run when one ambushes him and holds him at gunpoint. The slaves are no match for the Daleks, who begin exterminating them. Seeing this, the Doctor throws his hat on the Dalek's eye-stalk, blinding it. As the Dalek fires around blindly (nearly killing Davros in the process), the Doctor attaches an explosive to it and blows it up, then activates the bomb detonator and destroys the attacking Dalek squad. He takes Davros into the custody of the former slave workers. Davros shall be placed in Cryogenic suspension and taken to Earth to stand trial for his crimes. The Doctor and Romana surreptitiously leave the Movellan ship before take-off and return to the TARDIS where, after having cleared the fallen rocks away, they remark on the fact that whoever makes mistakes often wins (as the Doctor knows only too well). They enter the TARDIS and dematerialise, only to rematerialise a few seconds later after the Doctor presses the wrong switch. After Romana points out this mistake, the TARDIS dematerialises again — successfully this time.

Planets

 * Skaro is known as 'D5 Gamma Z Alpha' to the Movellans.
 * Skaro is still radioactive. The Daleks have abandoned it.
 * A dead slave was a pilot in the 3rd Galactic Fleet of Kantra. According to Romana, the planet is a tropical paradise.
 * The planet Magla is actually an 8,000-mile-wide amoeba that's grown a crusty shell.
 * An unnamed human slave is from the planet Sirian.

 * Davros is imprisoned in a cryogenic freezer.

Robotics

 * According to the Doctor, when mending a robot's brain Arrow A always points to the front.
 * K9 suffers from a form of laryngitis.

Time Lords

 * According to Romana, Time Lords are trained to be able to stop their hearts at will. This allows her to feign death.

 * The Daleks alloted to destroy the Movellan spacecraft are charged with explosives for more than half a megaton.

Story notes

 * The Skaro sound effects from TV: The Daleks are reused here.
 * In episode one where Romana changes her bodies, one of her costumes is Zilda's from TV: The Robots of Death.
 * Tim Barlow, who plays Tyssan, was partially deaf, but could lip-read and ran a school for deaf actors.
 * This is Terry Nation's final script credit on Doctor Who. However, director Ken Grieve claimed that the script was in fact "98% written by" script editor Douglas Adams. (BBC DVD: Destiny of the Daleks). These remarks seem consistent with comments by Adams quoted in Don't Panic by Neil Gaiman (published within the lives of both Adams and Nation). Adams states therein that he had discovered that other writers on Doctor Who considered it the role of the script editor to get the scripts into the correct broadcast order.
 * Romana wears a pink and white outfit stylistically similar to the Doctor's, complete with scarf.
 * The Davros mask was Michael Wisher's from TV: Genesis of the Daleks, and was only repaired to fit David Gooderson as there wasn't money in the budget to construct a new mask for Gooderson. Because the mask was too small to fit properly, Davros's mouth is noticeably stiff whenever he talks.
 * The addition of Douglas Adams is evident here with references to The Hitchhiker's Guide to the Galaxy and Adams' own brand of humour.
 * A steadycam — a rig used to obtain smooth, stable shots from a handheld camera — is used for the first time in this story.
 * The three alternative physical forms of Romana seen in part one were played by Yvonne Gallagher, Lee Richards and Maggy Armitage respectively, who remained uncredited both on-screen and in Radio Times.
 * Although K9 has no dialogue in this story due to suffering from laryngitis, he is heard to croak at the start of episode one. The croak was provided by Roy Skelton.
 * This story has (arguably) a Dalek joke, one of the few attempts in the series to add an element of humour to the Daleks. The Doctor climbs up a shaft, and from the top, taunts a pursuing Dalek, "If you're supposed to be the superior race of the universe, why don't you try climbing after us?" The Dalek fires at the Doctor in frustration. Other attempts at humour occur in TV: The Chase and TV: Doomsday. Incidentally, it is later established on screen in TV: Remembrance of the Daleks that Daleks can in fact elevate to surmount obstacles of height (a fact initially revealed in the original Daleks comic strip of the 1960s). In the Ninth Doctor episode TV: Dalek the (in)ability to navigate stairs is again made into a joke and shown to be false, they can hover up stairs.
 * The pink costume worn by Romana was worn again by Lalla Ward in the infamous "Dr. Who Meets His Match" TV commercials for Prime Computers of Australia, which ended with the Doctor proposing marriage to her.
 * This is currently the only story since 1973's The Green Death where each individual segment is labelled as an "Episode" rather than a "Part", the latter having been utilised since The Time Warrior.
 * Cassandra (Movellan Guard) is credited for episode four, but actually appears in episode three.
 * The effects of the Daleks' weapons hitting their targets are changed from previous stories: rather than the whole screen turning negative, only the basic area around the victim becomes so.
 * Parts of the Dalek slaves' costumes were recycled from previous aliens — for example, one wears the costume (but not the mask) of a Draconian, another the trousers from an SV robot (TV: The Robots of Death), another has the head of a humanoid-form Axon, and another is wearing a blue Morestran spacesuit.
 * Episode four has no incidental music.

Ratings

 * Episode one - 13.0 million viewers
 * Episode two - 12.7 million viewers
 * Episode three - 13.8 million viewers
 * Episode four - 14.4 million viewers

Myths

 * K9 does not appear because a replacement for John Leeson (who voiced K9) had not yet been cast. David Brierley had already been given the role over three months before the serial was made (specifically, for The Creature from the Pit, which was the actual first story filmed for Season 17). The actual reason for K9's absence was because the prop was unsuitable for the large amount of location filming. In addition, David Bailey's "Fact of Fiction" article in Doctor Who Magazine #389 states that Terry Nation had refused to include K9 in his storyline, as he felt that for the Daleks not to be able to destroy K9 would make them seem weak.
 * Mary Tamm either refused to film the regeneration scene from Romana I to Romana II, or was unable to do so because she was pregnant. According to comments made by Tamm in the 2007 Key to Time DVD set, she was willing and available to film the scene, but was not invited.
 * Romana used up several of her allotted regenerations frivolously by trying on the different forms. This has never been supported by other stories or media. The Christmas Invasion revealed that Time Lords have the ability to regrow severed limbs within fifteen hours of regeneration, suggesting a similar ability to change form might have been possible soon after her regeneration.
 * The DVD release claims that the original Dalek city corridor sound effect (The Daleks) is reused in this story; the effect used is the atmosphere of the planet Mira (The Daleks' Master Plan), itself reused as the atmosphere of the underground base of The Sea Devils.

Filming locations

 * Winspit Quarry, West Matravers, Dorset
 * Binnegar Heath, Wareham, Dorset
 * KJP Trading, 250 Western Avenue, Acton
 * BBC Television Centre (TC3 & TC1), Shepherd's Bush, London

Production errors

 * In the underground scenes, set lights can be seen, most notably in episodes one and two in the pit Romana falls down.
 * Because the Dalek props had severely deteriorated in storage as the result of poor practices, they are rife with cracks, dents (particularly in their gunsticks, where the outer rails are conspicuously caving in), and misplaced sections. The clear tape used to repair some of the damage is clearly visible from the light it ends up reflecting, and one Dalek's lower section is longitudinally symmetrical rather than being shallower at the front than at the back.
 * In episode four, a Dalek moves up a small slope. When it does this, a hand can just slightly be seen at the edge of the screen pushing it up the slope.
 * When the slaves storm the Movellan's ship, the one wearing a Draconian-style outfit is killed, yet he is later seen alive and well.
 * Close-up shots of the Movellan ship burying its lower section are poorly scaled, giving the impression of giant grains of sand.
 * After the Doctor escapes from Davros in episode three, in an overdubbed line of dialogue Davros orders that the slaves be exterminated, yet this never transpires. The DVD production notes acknowledge that this line of dialogue appears to serve no purpose.
 * Plausibly, this piece of clumsy editing could be a "Han shot first" moment. In the preceding scene, the Doctor agrees to spare Davros for the lives of the slaves ... then immediately reneges on the deal and tries to kill Davros (Justifiable, but rather unheroic). Making Davros the first to break his word could be argued to make the Doctor's betrayal seem less cynical.
 * Just as the Daleks have captured Davros, the leader Dalek's midsection moves.
 * In episode four, there is a scene where you can clearly see though a Dalek's midsection.
 * When Davros tries to escape near the end of the serial (while at the same time describing his proposed improvements to the Daleks), it is clear from David Gooderson's gyrations that the actor is simply pushing a modified swivel chair to move about.
 * In the same scene, Davros hits the side of the door on his way out, causing it to visibly shudder.
 * Still in this scene, after the camera can see Davros again, a Dalek's top section comes off its body.
 * David Gooderson's voice acting for certain additional Daleks noticeably stands out from the acting provided by Roy Skelton.

Continuity

 * The Doctor revisits Skaro. (TV: The Daleks, The Evil of the Daleks, Genesis of the Daleks)
 * Davros was thought exterminated when the Doctor previously met him. (TV: Genesis of the Daleks)
 * PROSE: War of the Daleks retcons almost everything in this story, such as revealing that it took place not on Skaro, but on a terraformed Antalin. The retcon is made through the Dalek Prime. It is possible that the Dalek Prime was lying, as his alleged scheme seems very implausible.
 * The Doctor recognises the form of Princess Astra, whose appearance Romana has decided to emulate in her new incarnation. (TV: The Armageddon Factor)
 * There have been several attempts to explain Romana's regeneration sequence in this story.
 * Unknown to the Doctor, Romana suffers damage due to exposure to the Key to Time. Just as she is about to regenerate, a humanoid manifestation of the TARDIS, jealous of Romana, traps her in a force field. It proceeds to pretend to be Romana, changing into different forms until finally becoming a double of Princess Astra. This manifestation is the one who appears in this serial. Realising the error of its ways after that adventure, it releases Romana, but not before making the female Time Lord assume the image of Astra. (PROSE: The Lying Old Witch in the Wardrobe)
 * Romana forced her own regeneration to prevent an ancient Gallifreyan evil called Pandora from gaining power over her. (This explanation may or may not be consistent with the previous one.) (AUDIO: Lies)
 * The creators of the Key to Time re-disguised its final segment as Romana, which is why she changed and why she chose Astra's form. (It is possible that the previous explanation was arranged by the Key's makers to facilitate this one.) (AUDIO: The Chaos Pool)
 * During her first incarnation, Romana previously encountered the Daleks in the Proxima System. (AUDIO: The Dalek Contract / The Final Phase) After leaving the TARDIS and returning to Gallifrey, she was held prisoner by the Daleks for two decades before escaping with the help of the Sixth Doctor. (AUDIO: The Apocalypse Element) Later still, the Daleks invaded the Gallifrey of an alternative timeline while Romana was serving as its Supreme Leader. (AUDIO: Arbitration, Extermination)
 * The Matrix contained information about the Daleks and Movellans being engaged in 4-X-Alpha-4 in 4949 (AUDIO: Neverland) although the conflict was implied to occur approximately 1000 years before the 41st century. (PROSE: Mission to the Unknown)
 * The Twelfth Doctor, Bill Potts and Nardole arrived in the middle of a battle during the Dalek-Movellan War. (TV: The Pilot)
 * After participating in the invasion of Kantra, a Dalek vessel containing the Emperor's Personal Guard crash-landed on the Grade 3 planet Strellin. (AUDIO: Order of the Daleks)
 * The Movellans defeated the Daleks in a battle in Traxana's sector of space during the Dalek-Movellan War. (AUDIO: Alien Heart)
 * The Doctor uses his hat to obscure a Dalek's eyepiece, a tactic he previously used on Trodos in his second incarnation. (COMIC: The Trodos Ambush)

 * The release of this DVD earned a mention in the July 2008 issue of "Sky at Night" magazine. In that issue, writer Sean Blair reviews the book "Jane's Space Recognition Guide" and jokingly suggests that its publication may have been prompted by the Doctor's mention of a Jane's Spacecraft Guide in this story.
