'''''The Dalek Invasion of Earth''''' is the second [[Serial (radio and television)|serial]] of the [[Doctor Who season 2 (1964–1965)|second season]] of the British [[science fiction television]] series ''[[Doctor Who]]''. Written by [[Terry Nation]] and directed by [[Richard Martin (British director)|Richard Martin]], the serial was broadcast on [[BBC1]] in six weekly parts from 21 November to 26 December 1964. In the serial, the [[First Doctor]] ([[William Hartnell]]), his granddaughter [[Susan Foreman]] ([[Carole Ann Ford]]), and teachers [[Ian Chesterton]] ([[William Russell (English actor)|William Russell]]) and [[Barbara Wright (Doctor Who)|Barbara Wright]] ([[Jacqueline Hill]]) discover that the Earth in the 22nd century has been occupied by [[Dalek]]s. They work with a human resistance group to stop the Daleks from mining out the Earth's core as part of their plan to pilot the planet through space.

The serial was commissioned following the success of the Daleks from the [[The Daleks|titular serial]] of the [[Doctor Who season 1 (1963–1964)|first season]]. The serial also marks the final regular appearance of Ford as Susan, having been dissatisfied with the character's development. The writers had considered introducing Susan's replacement within ''The Dalek Invasion of Earth'', but delays in contract renewals forced it to the following serial. The serial was the first major location shoot for ''Doctor Who'', with production taking place at [[Trafalgar Square]], [[Westminster Bridge]], and the [[Royal Albert Hall]]. The serial premiered with 11.4&nbsp;million viewers, maintaining strong viewers across the six weeks. Contemporary reactions were positive, with many praising the return of the Daleks. Retrospective reviews were also positive, with particular praise directed at the first episode's [[cliffhanger]] and Susan's emotional departure, though the direction and pacing has been criticised. The serial later received several print adaptations and home media releases.

== Plot ==
After the [[TARDIS]] materialises, the [[First Doctor]] ([[William Hartnell]]), [[Susan Foreman]] ([[Carole Ann Ford]]), [[Ian Chesterton]] ([[William Russell (English actor)|William Russell]]), and [[Barbara Wright (Doctor Who)|Barbara Wright]] ([[Jacqueline Hill]]) surmise that they have landed in London, but find it in ruins. The Doctor and Ian stumble across an army of Robomen as a [[Dalek]] rises from the [[River Thames]]. The Daleks take the Doctor and Ian onboard their saucer. Resistance members explain that the Daleks invaded Earth in the aftermath of a meteorite bombardment ten years prior.

Barbara and Susan are taken by refugees to a nearby shelter in an abandoned [[London Underground|Underground]] station, where they meet resistance members who are planning an assault on the Daleks. The resistance leader, paraplegic scientist Dortmun (Alan Judd), has created a bomb to destroy the Daleks' outer casings. Susan, Barbara, and the resistance team attack the Daleks using the bombs, but they are ineffective. David ([[Peter Fraser (actor)|Peter Fraser]]) rescues the Doctor with Susan while Barbara gets separated. Ian hides as the saucer leaves for the Dalek mining operations. There, he escapes the [[Slyther]] (Nick Evans), a pet of the [[Dalek variants#Mark 2 Daleks|Black Dalek]]. He eventually hides in the mine and becomes trapped in a capsule filled with explosives. The Doctor, Susan, and David arrive at the cliffs overlooking the mine; the Doctor sends David and Susan to interfere with the Daleks' radio signals, while he climbs into the mine.

Dortmun sacrifices himself so that Barbara and Jenny ([[Ann Davies (actress)|Ann Davies]]) can escape. They repair an old truck and head for the mining operations, but are reported to the Daleks when seeking shelter and sent to work. They are later brought before the Black Dalek and discover that the Daleks are drilling through the [[Earth]]'s crust to blow out its core, the intention being to replace the core with a device to pilot the planet like a spacecraft. The Daleks imprison Barbara and Jenny and set the explosive-filled capsule in position, but Ian jams the capsule half-way down the shaft. The Doctor frees Barbara and Jenny. With the radio signals damaged, Barbara and the Doctor order the Robomen to destroy the Daleks, and the human slaves rebel. The bomb destroys the Dalek fleet and causes a [[volcanic eruption]] in England.

Back in London, David begs Susan to stay and marry him. Susan agonises, declaring her love but admitting that she must leave. The Doctor locks the TARDIS doors and bids Susan an emotional farewell, telling her that she deserves a normal life with David. He promises to return one day, and sets the TARDIS in motion. Susan drops her TARDIS key and leaves with David.

== Production ==
=== Conception and writing ===
In March 1964, story editor [[David Whitaker (screenwriter)|David Whitaker]] formally commissioned [[Terry Nation]] to write a serial for ''[[Doctor Who]]''{{'}}s [[Doctor Who season 2 (1964–1965)|second season]] following the success of the Daleks from the [[The Daleks|titular serial]] of the [[Doctor Who season 1 (1963–1964)|first season]], as well as Nation's quick and effective work on ''[[The Keys of Marinus]]''.{{sfn|Wright|2017|p=16}} The commission was made under the title ''Doctor Who and the Daleks''. Nation delivered the storyline for the serial in mid-April 1964 under the name ''The Return of the Daleks''.{{sfn|Wright|2017|p=17}} The serial was retitled ''The Dalek Invasion of Earth'' by September; ''The Daleks in Europe'' appeared on some design material.{{sfn|Wright|2017|p=28}}

The Dalek props were refurbished for the serial, adding new eyestalks, a dish receptor, improved bases for movement, and a new pedal mechanism.{{efn|Dalek designer [[Raymond Cusick]] had proposed the addition of a pedal mechanism for the original design the previous year.{{sfn|Wright|2017|p=24}}}}{{sfn|Wright|2017|p=24}} The serial's score was composed by [[Francis Chagrin]]. Around 18 minutes of incidental music for the first three episodes was recorded on 10 September 1964 at [[Maida Vale Studios]],{{sfn|Wright|2017|p=29}} and 12 minutes for the final three episodes was recorded by five musicians on 8 October.{{sfn|Wright|2017|p=32}} Chagrin had conceived the music from the serial's final scene some time before production and was "dying to use it".<ref>{{cite AV media |last1=Russell |first1=Gary |author-link1=Gary Russell |last2=Martin |first2=Richard |author-link2=Richard Martin (British director) |last3=Lambert |first3=Verity |author-link3=Verity Lambert |last4=Ford |first4=Carole Ann |author-link4=Carole Ann Ford |last5=Russell |first5=William |author-link5=William Russell (English actor) |date=2003 |title=The Dalek Invasion of Earth'': "Flashpoint"'' |medium=DVD commentary |time=23:10 |publisher=[[2 Entertain]] }}</ref>

=== Casting and characters ===
[[File:Caroleanneford86.jpg|thumb|right|upright|''The Dalek Invasion of Earth'' is the final regular appearance of [[Carole Ann Ford]] as [[Susan Foreman]].{{sfn|Wright|2017|p=17}}]]

On 12 March 1964, trade paper ''Television Today'' announced that Carole Ann Ford would depart from her role as Susan at the end of her contract, due to her dissatisfaction with the character's development.{{sfn|Wright|2017|p=17}} Whitaker wanted a strong reason for Susan's departure. To assist the story's development, Ford and Hartnell were invited to stay with Nation and his wife over a weekend in August.{{sfn|Wright|2017|p=19}} In June 1964, head of serials [[Donald Wilson (writer and producer)|Donald Wilson]] considered continuing the show without the character of Barbara, and with a younger actress for Susan.{{sfn|Wright|2017|p=18}} Delays by Controller of Programmes [[Donald Baverstock]] to renew cast contracts meant that Susan's replacement, then intended to be Jenny (originally known as Saida), could not be introduced in the serial.{{sfn|Wright|2017|pp=23–24}} Director [[Richard Martin (British director)|Richard Martin]] asked Ann Davies, who was cast as Jenny, if she would be available as a regular cast member, but he could not offer the role.{{sfn|Finklestone|2003|loc=06:21}}

''The Dalek Invasion of Earth'' was the first speaking role of [[Nicholas Smith (actor)|Nicholas Smith]], who portrayed Wells. When Smith discovered he was only starring in one episode, he approached Martin; Martin asked him to return in a later episode to lead the human rebellion.<ref name="Future Memories"/><!-- 03:43 --> Jean Conroy, who played one of the women in the woods in the fifth episode, died in a street accident on 14 November; the episode was broadcast posthumously.{{sfn|Wright|2017|p=33}}

=== Filming ===
''The Dalek Invasion of Earth'' was the first major location shoot for ''Doctor Who''. Filming in [[35 mm movie film|35mm]] began at [[Trafalgar Square]] at around 5:30&nbsp;a.m. on 23 August 1964, consisting of shots of a deserted city.{{sfn|Wright|2017|p=25}} The design team added Dalek markings on landmarks such as [[Nelson's Column]], which police requested they remove.{{sfn|Wright|2017|pp=25–26}} On the same day, filming took place at [[Equestrian statue of the Duke of Cambridge, Whitehall|the statue of the Duke of Cambridge]] in [[Whitehall]], [[Westminster Bridge]], and the [[Royal Albert Hall]]. Martin had an agreement with police to vacate parts of central London for filming. Production resumed two days later on 25 August at the closed [[Wood Lane tube station (Metropolitan line)|Wood Lane tube station]].{{sfn|Wright|2017|p=26}} On 27 August, filming took place at [[Hammersmith Bridge]]. The location was chosen as it provided easy access to a hospital in case any performers swallowed river water; a taxi remained on standby. Dalek operator [[Robert Jewell]] could not gain enough traction to move his Dalek out of the river; the prop was attached to a cable to help. ''Doctor Who''{{'}}s first filming in a [[quarry]] took place on 28 August at [[Stone, Kent]].{{sfn|Wright|2017|p=27}} [[Peter Hawkins]] and [[David Graham (actor)|David Graham]] recorded Dalek voiceovers on 16 September.{{sfn|Wright|2017|p=29}}

Rehearsals for the first episode began on 14 September in [[White City, London|White City]], and weekly studio recording began on 18 September in Studio 1 at [[Riverside Studios]]. Though smaller overall than [[Lime Grove Studios]], the complex used for previous serials, Riverside offered well-equipped and larger individual studios.{{sfn|Wright|2017|p=29}} During camera rehearsals for the third episode on 2 October, Hartnell injured his back when a prop ramp malfunctioned;{{sfn|Wright|2017|p=31}} when Martin apologised for the incident, Hartnell assured that he would be fine, but producer [[Verity Lambert]] insisted that he take several days to rest.<ref>{{cite AV media |last1=Russell |first1=Gary |author-link1=Gary Russell |last2=Martin |first2=Richard |author-link2=Richard Martin (British director) |last3=Ford |first3=Carole Ann |author-link3=Carole Ann Ford |last4=Russell |first4=William |author-link4=William Russell (English actor) |date=2003 |title=The Dalek Invasion of Earth'': "The Walking Ally"'' |medium=DVD commentary |time=2:52 |publisher=[[2 Entertain]] }}</ref> Following discussions between Hartnell's solicitors and the BBC's, the BBC denied liability and paid for an X-ray. Hartnell was given a week off to recover, and the fourth episode underwent minor rewrites; [[Edmund Warwick]] doubled for Hartnell as The Doctor in the episode.{{sfn|Wright|2017|p=32}} The final episode was recorded on 23 October, marking a year of production since the filming of the show's [[An Unearthly Child|first serial]];{{sfn|Wright|2017|p=34}} recording was delayed by half an hour due to some technical facilities being used by coverage of the [[1964 Summer Olympics]].{{sfn|Wright|2017|p=32}} The production crew anticipated the final episode to be one of the most technically complex. The recording suffered some camera and sound issues, causing Hartnell to stumble some speeches. Hartnell omitted two lines from the Doctor's closing speech to Susan.{{efn|The two lines omitted by Hartnell include one earlier in the speech: "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 second line was meant to end the speech: "And remember love is the most precious jewel of all."{{sfn|Wright|2017|pp=34–35}}}} Ford recorded footage of the cast between camera rehearsals on her personal [[8 mm film]] camera.{{sfn|Wright|2017|p=34}}

=== Critical response ===
[[File:Doctor Who - Susan departure.ogv|thumb|right|upright=1.2|thumbtime=0:19|The serial's final scene—in which [[First Doctor|the Doctor]] bids farewell to [[Susan Foreman|Susan]], the show's first [[Companion (Doctor Who)|companion]] departure—was praised for its emotional impact and [[William Hartnell]]'s performance.{{sfn|Howe|Walker|1998|p=67}}{{sfn|Muir|1999|p=99}}<ref name="Radio Times Review"/>|alt=The Doctor says goodbye to his granddaughter while standing in the TARDIS.]]

At the BBC Programme Review Board after the broadcast of the first episode in November 1964, director of television [[Kenneth Adam]] called it "interesting".{{sfn|Wright|2017|p=38}} The Audience Research Report was higher than usual, with praise for the production and atmosphere; the primary complaint was the lack of Daleks, and some viewers felt it was too gruesome for children.{{sfn|Wright|2017|p=42}} The Review Board described the third episode as "outstanding".{{sfn|Wright|2017|p=39}} The following week, executives of the Board felt that the show's quality was consistently high. Adam indicated that [[Director-General of the BBC|Director-General]] [[Hugh Greene]] was eager to see the Daleks return in future stories.{{sfn|Wright|2017|p=41}} [[T. C. Worsley]] of the ''[[Financial Times]]'' praised the serial for creating a universal image for the Daleks. On 27 May 1965, critic Frederick Laws wrote that he had banned his children from watching ''Doctor Who'' due to the ending of the serial's first episode.{{sfn|Wright|2017|p=43}}

Retrospective reviews of the serial were generally positive. In ''[[The Discontinuity Guide]]'' (1995), [[Paul Cornell]], [[Martin Day (writer)|Martin Day]], and [[Keith Topping]] praised the exterior sequences of the Daleks, though noted the less impressive production of the Slyther.{{sfn|Cornell|Day|Topping|1995}} In ''The Television Companion'' (1998), [[David J. Howe]] and Stephen James Walker described the serial as "one of the series' all-time greats", with impressive scripting and location filming despite some clumsy direction; they also praised the "poignant and moving" final scene.{{sfn|Howe|Walker|1998|pp=65–67}} In ''A Critical History of Doctor Who'' (1999), [[John Kenneth Muir]] found the serial to be one of ''Doctor Who''{{'s}} darkest, and praised the location shooting and the characterisation of Susan, though noted some sexism in the Doctor's final remarks and criticised some "positively amateurish" special effects.{{sfn|Muir|1999|p=98–99}}

In 2008, Mark Braxton of ''[[Radio Times]]'' praised the supporting cast, location filming, and emotional ending, but noted the continuity errors concerning the Daleks and the production shortcomings as a result of the serial's ambition.<ref name="Radio Times Review"/> In a 2011 review, ''[[The A.V. Club]]''{{'}}s Christopher Bahn criticised the serial's slow pacing and the uninteresting concept of the Robomen, and noted that Susan's departure lacked dramatic impact because the Doctor chose for her; however, he praised the first episode and its [[cliffhanger]], and the characterisation of the Doctor.<ref name="AV Club Review"/> In 2010, [[Charlie Jane Anders]] of ''[[io9]]'' listed the first episode's cliffhanger as one of the greatest in the show's history.<ref name="io9"/> ''The Dalek Invasion of Earth'' was voted the best First Doctor story by ''[[Doctor Who Magazine]]'' readers in 2020; writer Nick Setchfield cited the atmosphere, character, and narrative as its greatest elements, and the first episode's cliffhanger and Susan's departure among its best moments.{{sfn|Setchfield|2020|p=49}}
