Planet of the Daleks

Planet of the Daleks is the fourth serial of the tenth season of the British science fiction television series Doctor Who, which was first broadcast in six weekly parts on BBC1 from 7 April to 12 May 1973.

Continuing from the events of the serial Frontier in Space, the story involves a small team of Daleks plotting to revive an army of Daleks which are being kept in suspended animation on the planet Spiridon.

Plot
The Third Doctor has been wounded after being shot by the Master. Jo helps the Doctor into the TARDIS, where he sends a message to the Time Lords before he collapses then falls into a coma. The Time Lords direct the TARDIS to the planet Spiridon, where Jo leaves the TARDIS in an attempt to find help, and encounters a party of Thals, the Daleks' oldest enemy. The Thals rescue the Doctor from the TARDIS, the outside of which has been overtaken by a lethal fungus, and explain to the Doctor that the Daleks have set up a research base on the planet to gain the native Spiridons' power of invisibility.

The Thals take the Doctor back to their ship, but the Daleks arrive first, destroy the ship and capture the Doctor. He presumes Jo to be dead, but fortunately she had already been removed from the ship by a Spiridon named Wester, having become infected with the fungus, which Wester cures. As the Doctor is held captive in the Dalek base, another party of Thals arrives and informs the first group that their intelligence had been mistaken; there isn't just a small research team of Daleks on the planet, but an army of ten thousand, which will form a galactic invasion force.

As the Doctor and a fellow captive Thal break out of their cell, the other Thals break into the base, and the Doctor confirms the existence of the Dalek army, before the group escapes and reunites with Jo and Wester. The Doctor realises that making use of the planet's natural ice volcanos will be key to defeating the Daleks. Meanwhile, a Dalek ship commanded by a Supreme Dalek lands on the planet, and the Supreme executes the lead Dalek for failing to deal with the Doctor and the Thals.

The group sneaks back into the base, where the Daleks are preparing a bacterial weapon in a laboratory chamber to destroy all life on the planet. However, Wester unleashes the weapon prematurely, ensuring he is its only casualty and creating a no-win situation for the Daleks, where those previously inoculated in the laboratory cannot leave or open the chamber, lest they infect their bretheren. The Doctor, Jo, and the Thals return to the cavern where the Dalek army is being brought out of stasis, and the Doctor sets off an explosion that floods the entire base with liquid ice, freezing the army. The Thals take the Supreme Dalek's ship to return to their home world of Skaro, while the Doctor and Jo narrowly get away in the TARDIS, though the Supreme Dalek vows that they are not defeated, and that they will someday thaw their army back out. The Doctor offers to take Jo anywhere in time and space, but after their recent adventures, Jo is happy to go back to Earth.

Production
The story was originally commissioned as Planet of the Daleks, but during production it briefly changed to Destination: Daleks. Episodes 2 & 4 do not feature a reprise of the previous episode's cliffhanger ending, while the reprises in Episodes 3 and 5 are re-performances. Though this latter technique was commonplace in 1960s episodes, by this time in the programme's history it was an approach almost never used.

The Dalek Supreme in this story was a modified prop from the film Daleks' Invasion Earth 2150 A.D. (1966) that had been given to Terry Nation. Its eyestalk has been replaced with a conventional torch, which flashes when it speaks.

For many years Episode 3 of the serial existed in the BBC Archives only as a black-and-white 16mm telerecording, as the 625-line colour PAL transmission master videotape for that episode was wiped for reuse by the BBC in 1976. Episode 3 was restored to full colour in 2008, using a combination of computer colourisation by Legend Films with software developed by the Colour Recovery Working Group. This version was released on DVD in 2009. The colour masters for the other five episodes are still extant.

Cast notes
Bernard Horsfall had previously appeared as Lemuel Gulliver in The Mind Robber (1968) and as the First Time Lord in The War Games (1969). He appeared once more in The Deadly Assassin (1976), as Chancellor Goth. All these serials were directed by David Maloney.

Prentis Hancock had appeared as a reporter in Spearhead from Space (1970), and would return as Salamar in Planet of Evil (1975) and as the Shrieve Captain in The Ribos Operation (1978).

Broadcast and reception
The serial was repeated on BBC One on Friday evenings between 5 November and 17 December 1993, as part of "Doctor Who and the Daleks", celebrating 30 years of Doctor Who. Each episode was preceded by a specially made 5 min vignette, which were 'Bigger on the Inside', 'The Antique Doctor Who Roadshow', 'Missing in Action', 'I Was That Monster', 'The Master' and 'U.N.I.T. Recruitment Film'. The repeat of Episode 3 of Planet of the Daleks on 19 November 1993 was shown in black and white, the only time since June 1969 that a Doctor Who episode has been broadcast in black and white on BBC One. The ratings achieved were 3.6, 4.0, 3.9, 3.3, 3.3 and 3.5 million viewers, respectively.

Paul Cornell, Martin Day, and Keith Topping gave an unfavourable review of the serial in The Discontinuity Guide (1995), writing that it was "a typical coincidence-based Dalek story of hammy deaths and ridiculous escapes. A reworking of the themes and set pieces of The Daleks, with pacifism and an anti-nuclear stance becoming weak monologues on bravery and caution." In 2010, Mark Braxton of Radio Times awarded it three stars out of five, describing Planet of the Daleks as "an exciting story, but a tawdry spectacle" with it being "continually compromised" in production values. While he found that some elements of the story were enjoyable, he felt that it lacked emotional continuity and the Daleks did not impress. DVD Talk's John Sinnott found the story more enjoyable than Frontier in Space, praising the way Nation "filled the plot with creative other-worldly creatures and devices and used them nicely to move the story". In the book Doctor Who: The Episode Guide, Mark Campbell also rated it as better than Frontier in Space, awarding it eight out of ten, concluding "a believable jungle setting and ambitious (if unoriginal) ideas make this live-action comic strip romp breeze along in fine style."

In print
A novelisation of this serial, written by Terrance Dicks, was published by Target Books in October 1976. The novelisation opens with the cliffhanger from Frontier in Space of a comatose Doctor pursuing the Daleks through space, even though this was removed from the Space War novelisation. A German translation was published in 1980.

In 1995 an abridged version of the novel was issued by BBC Audio as an audio book, read by Jon Pertwee. It was later reissued on the MP3-CD release Tales from the TARDIS Volume 2. An unedited audio book version was released in June 2013, narrated by actor and writer Mark Gatiss, with Dalek voices performed by Nicholas Briggs.
