"This episode was first broadcast on 26 December 1964." "12.4 million people watched the Boxing Day transmission." "This reprise sequence was played in from the film recording of the previous week's episode." "In the week between recording sessions, a small change was made to this model." "That was last week's model, and now this week's version, with added Dalek." "In the first draft, this episode was entitled:" "EARTH REBELS" "A scene was cut here in which the Daleks register a breakdown in the capsule's "descension mechanism", and a working party is sent to pull it manually back up to the starting position." "Exactly how Ian manipulates the wiring kept getting changed in pre-production." "Originally, he was to break a piece of metal off the capsule to use as a screwdriver." "The props department improbably proposed that he would get out a nail file, and three days before filming, they were asked instead for "One rather nice but very strong, not too bulky penknife"." "Yet in the end, he still had to use his bare hands!" "The recording broke after this shot while the capsule was moved to a higher position, giving Ian room to jump down." "A children's slide was set up in the studio for Ian to fall down the shaft in the live-action shot coming up." "The rock walls were electronically inlaid into the picture to conceal the slide." "In the studio, this corridor was set up immediately to the right of the Kew Bridge set." "See if you can spot the Kew set through the end door in a later corridor scene." "In the first draft, the Dalek Supreme summons the entire Dalek invasion force to the mine:" ""It is my wish that all our people who have contributed to its success shall witness the final achievement."" "The mention of extermination as a "final solution" was a very late addition which does not appear in any version of the script." "The phrase alludes to the Nazis' "final solution" to the so-called "Jewish problem" - genocide in death camps like Auschwitz." "The character of Barbara, a history teacher in her earthly life, was devised to be a source of information in the serials set in the past." "But a little historical learning can be useful even when you're trapped in the future." "The Indian Mutiny of 1857 was sparked by crass religious insensitivity by the country's British imperialist masters." "The Boston Tea Party of 1773 was a protest by pre-revolutionary American colonists about British taxation." "Disguised as Red Indians, the Americans made their way aboard British ships and dumped their cargos of taxable imported tea into Boston harbour." "Robert E. Lee (1807-70) was an American Civil War general (on the side of the slave states), and the Carthaginian general Hannibal invaded Italy with elephants in 217 BC." "It's standard stage practice that the person being restrained is the one in control." "Here the principle is reapplied to the problem that the Daleks can't actually hold anything with their suckers." "In the camera script, the Dalek Supreme has another order to give:" ""Alert flying saucers to hover directly over the mine area to take off all Daleks at my command!"" "This set was built on a rostrum raised about four feet above the studio floor." "The set was in a corner of the studio, just to the right of the ship's control room." "A long section of dialogue was cut here, in which David presses Susan about what she will do after the Daleks are defeated, and she won't give him a straight answer." "The rocks on the side of the crater aren't as solid as they might be!" "Here you can see how Ian's clothes have progressively deteriorated through the serial's later episodes." "This and the next set you'll see were adjacent and connected by the stopper-shaped hatch." "This was in a corner of the studio, next to the capsule control set." "The different lighting quality in the two connected sets is partly created through the floor colouring - light cream in here, black in here." "What you're hearing is the Dalek Supreme's pedals creaking." "The new pedal-driven mechanism enabled the Daleks to move more smoothly across the floor." "But there were disadvantages." "The noise was one, and another was that the operators couldn't move the casings laterally or turn them sharply." "A sequence was cut here in which the Doctor uses a reflection to neutralize the photoelectric cell on the door." "In the rehearsal script, the Doctor objects to being called "Doc" because "it reminds me too much of that fearful vulgarian Nefertiti"." "(Nefertiti was a queen of Egypt in the 14th century BC.)" "Though the script specifies timbers, the production team considered using two railway sleepers to block the bomb." "Studio recording for this episode took place on 23 October 1964." "Recording started half an hour later than usual, at 9pm, and was scheduled to finish at 10.15pm." "In fact, recording wasn't completed until 10.32pm." "The overrun was partly caused by the number of recording breaks required to redress the sets." "For example, a recording break took place after this shot to move the bomb across the studio from the capsule control set into the shaft." "The floor of this set was painted light cream." "In the first draft, Doctor Who and Tyler find insulated wires outside the control room, strip them, and use the current to electrocute the Dalek operating the controls there." "This serial caused controversy in the tabloid press over its grim scenario, and inspired baseless rumours that Doctor Who would in future be censored by the BBC." "This led to at least one letter from a concerned parent pleading with the BBC to keep it thrilling and not give in to media pressure." "In reality, the serial was much admired by the BBC's senior management, and it was agreed to be "outstanding" in a programme review meeting." "The following year, 'The Dalek Invasion of Earth' was selected as the basis for the second Doctor Who cinema film, Daleks" " Invasion Earth 2150 AD (1966)." "The circular "Dalek's-eye view" is created by inlaying a moving mask around the edge of the picture." "The camera script says that the Doctor is "tugging his lapel defiantly"." "Unusually, this sequence was pre-recorded and cut in later." "This Dalek is a hollow dummy;" "note its solid base and lack of rubber fenders." "Does that brick wall look familiar?" "It's part of the Kew Bridge set." "If you were looking carefully, you'll also have seen the poster forbidding the disposal of dead bodies in the river, which the design department, interestingly, described as a "Large Dalek Sign"." "You are about to see the secret of how the Dalek props fitted together." "For rehearsals, the operators used to trundle around with the tops off." "One of the original objectives of Doctor Who's science fiction strand was to create convincingly unearthly points of view." "The Daleks' environment, for example, was designed to reflect the alien beings who inhabit it." "Their doors resemble their own shape, their screens are as circular as the peripheries of their vision, and their dials move anticlockwise." "Terry Nation proposed representing the eruption using clips from the film Volcano (1958), "and any available news footage"." "Nation also suggested using wax models to show Daleks melting in the heat." "In the planning stages, it was considered using a snow machine to throw up fine earth over the actors as the volcano erupted." "In the background is a scenic flat showing mountains, with a cyclorama behind it." "In the first draft, Doctor Who remarks, "The Earth rebelled and destroyed the invader."" "After this scene there was a 20-minute recording break to reset the studio." "Parts of the Dalek control set were struck (taken down) and the circular patterned walls of the Doctor's ship were taken from the Kew Bridge set, where they were being stored..." "..and set up on the other side of the studio." "If you think Wells hasn't got a lot to do in this episode, it's probably because he wasn't originally intended to appear at all." "He probably replaced one of the extras, Leslie Conrad, who was booked but not used." "The script specifies that the chimes "are not totally accurate"." "Kew Bridge was the largest single set used in this episode." "To its left was the small shaft where Ian intercepted the bomb, and it extended across into the corner of the studio." "The brief to the wardrobe department for Susan's damaged shoe was:" ""It should have no heel, be badly worn and have a few nails sticking out of it."" "Tyler's next line was cut:" ""There's not much left standing, but we're getting organised." "I'm taking over the old Admiralty building in Whitehall."" "In the first draft, Susan pointedly tells David, "I don't love you", more to convince herself than anything else." "After leaving Doctor Who, Carole Ann Ford went into rehearsals for a pantomime at Bromley New Theatre " "The Sleeping Beauty with Diana Dors, which opened on Christmas Eve 1964." "She later turned down offers to play schoolgirl characters, and did her best to shed her Doctor Who image by accepting sexy roles such as a murdered prostitute in Public Eye (1965) and a dubious French mistress in The Great St Trinian's Train Robbery (1966)." "The control room of the Doctor's ship was set opposite Kew Bridge, on the side of the studio nearest to the entrance to the scene dock." "for ease of setting the production's bulkiest, most cumbersome item, the hexagonal control panel." "The ship's doors opened towards the studio wall, with a clearance of about four feet." "The area behind the doors was set with black, and the floor was lacquered blue." "This was an emotionally difficult speech for William Hartnell, made doubly so by the fact that, when he played it, he was looking directly at Carole Ann Ford." "She was on the other side of the studio in her place on the Kew Bridge set, directly opposite the control room set." "It didn't help, either, that the sequence needed three retakes, twice because of technical problems, and once because Hartnell fluffed his lines." "In the final version, he truncated the speech slightly." "Here he was supposed to say," ""Work hard, both of you." "Be gentle with her, David," ""and show her that life on Earth with love and understanding can be a great adventure."" "The speech was supposed to end:" ""And remember, love is the most precious jewel of all."" "In the first draft, he says more about his return: "Make me proud of the world you build," he tells Susan." "In this shot, the ship is a superimposed photo caption." "The photo was taken on the morning of the studio day, and a 20x16 print was delivered back to the studio the same afternoon." "In the first draft, the serial closes with a scene in the ship in which the melancholy Doctor sees that Ian and Barbara are watching him, and "instantly reverts to his pepper self"." "Barbara kisses him on the forehead, and he grumpily calls her and Ian "sentimentalists"." "The episode, and the serial, ends on the discovery that Saida is now on board the ship." "The end of recording just after half past ten concluded a fraught and draining 90 minutes' work, and left producer Verity Lambert with a 17-minute overrun to explain to her superiors." "This saw the end of the first, year-long block of recording of Doctor Who - in effect, its first series." "But once Doctor Who was renewed, this serial and the one before were held back to start a second transmission season after a summer break." "This pattern was continued for the next three years." "And so it ended." "Carole Ann Ford left for her next job." "Four of the Daleks were sent to the BBC Visual Effects Store on the model stage at Ealing Studios, and the other two went back to terrorise more of Dr Barnardo's orphans." "The regular cast left for an unseasonal break and reassembled five weeks later to begin rehearsals for..." "The non-speaking prisoners included:" "Jim Appleby, Jonas Kurchi, Bill McAllister" "Peter Morton, Steve Pokol, Fred Taylor" "John Timberlake, Graham Tunbridge, Leslie Wilkinson" "The non-speaking Robomen were played by:" "John Caesar, Adrian Drotsky, Billy Moss, Reg Tyler" "Production text commentary written by Martin Wiggins"
