# Robot (Doctor Who)

Robot is the first serial of the 12th season in the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 28 December 1974 to 18 January 1975. It was the first full serial to feature Tom Baker as the Fourth Doctor, as well as Ian Marter as new companion Harry Sullivan. In the serial, the director of an English research institute plots to use an experimental robot to steal nuclear launch codes and blackmail the world's governments with them.
The serial brought a full end to the Pertwee era, as it was the final story with the production team of Barry Letts and script editor Terrance Dicks. It was also the final regular appearance of UNIT, who had become regulars starting with the first Jon Pertwee serial Spearhead From Space.
The episode received mixed reviews from critics, seeing praise for the acting, especially that of Baker and Marter, but criticisms due to stereotypical villains and a weak plot.

## Plot

Following his regeneration, the Fourth Doctor becomes delirious and erratic. The Doctor tries to sneak off in his TARDIS, but the Brigadier and Sarah Jane stop him, convincing him to help in finding the culprit in the theft of top secret plans for a disintegrator gun.
Sarah investigates the National Institute for Advanced Scientific Research, colloquially known as the "Think Tank". She finds that director Hilda Winters, her assistant Arnold Jellicoe, and Professor J.P. Kettlewell are developing a robot, K1, to be used to perform tasks in hazardous locations. Winters and Jellicoe have secretly instructed K1 to kill Cabinet Minister Joseph Chambers, and use a completed disintegrator gun to steal international nuclear launch codes from Chambers' safe. K1 discovers Sarah's presence, and Winters orders K1 to kill her. When UNIT arrives, the three conspirators and K1 escape with Sarah as their hostage.
Winters sends a list of demands to the world governments and gives them thirty minutes to comply, then orders Kettlewell to connect to the launch computers. Kettlewell, who never expected their plan to get to this stage, hesitates, and in the ensuing discussion, Sarah and Harry attempt to escape with Kettlewell's assistance. Winters orders K1 to stop them, but the robot inadvertently fires the disintegrator gun at Kettlewell, killing him. In a confused state due to the death of its creator, K1 falls to the ground and apparently shuts down.
As UNIT forces take Winters and Jellicoe away, K1 reactivates and attacks UNIT. K1 seeks out Sarah to protect her, a result of an Oedipus complex it developed from Sarah's previous compassion, according to the Doctor. The Doctor finds out about the living metal that Kettlewell used in constructing K1 and the metal virus he designed to reduce the world's metallic waste. He races back to Kettlewell's lab to synthesise a batch of the virus.The Brigadier fires the disintegrator gun at the robot, but the blast is absorbed by the living metal- and K1 grows to an enormous size. The Doctor returns, throwing a bucket of virus solution onto K1; the robot slowly shrinks before the virus consumes it. As they regroup back at UNIT headquarters, Sarah is saddened by the loss of K1. The Doctor offers to cheer her up with a trip in the TARDIS, extending the invitation to Harry as well.

## Production

As the Doctor was transitioning from the third to the fourth incarnations, changes were also occurring in the production department of Doctor Who. Barry Letts, who had been the producer since the second Jon Pertwee serial in 1970, was leaving the series, but would stay on to cast the part of the new Doctor as well as produce this debut serial. Letts would be succeeded for the next story by Philip Hinchcliffe, who trailed him on this story.
Terrance Dicks, who had worked on the series as a script editor since 1968, was also leaving, to be replaced by Robert Holmes. Holmes had been a writer for the show since season six and penned four stories in Pertwee's era, including Spearhead from Space (1970), the Third Doctor's first serial. Though Dicks was leaving as script editor, he would still be involved with the series as an occasional writer. Having previously helped write the serials The Seeds of Death and The War Games (both 1969), Dicks would write the first story for the incoming Fourth Doctor.
The K1 robot costume was designed by one of the series' regular costume designers at the time, James Acheson, and built by sculptor Allister Bowtell.

### Conception and writing

Terrance Dicks stated that a major influence for this story was King Kong (1933). The initial script was written before Tom Baker had been cast as the Fourth Doctor, and there was some discussion of returning to an older actor. This would have required a younger character to handle the action scenes, so the character of Harry Sullivan was created. This was Sullivan's debut story, but he had been mentioned in the final episode of the preceding serial, when the Brigadier telephoned him, requesting medical help for the Doctor.
Dicks included a number of elements from Spearhead from Space: the Doctor being disorientated after regeneration, going to hospital to recover, changing costume as a result of escaping from hospital in a hospital gown, viewing himself in a mirror to see his new face, and storing the TARDIS key in his shoe. These elements helped the audience with the transition between actors.

### Casting

It was known beforehand that Jon Pertwee would be leaving his role as the Third Doctor and that a new Fourth Doctor would need to be cast for the part. Tom Baker had previously had major parts in several films, including Nicholas and Alexandra (1971) and The Vault of Horror (1973), but had found himself unemployed as an actor and working in construction at the time. He had written to Bill Slater, the Head of Serials at the BBC, asking for work. Slater suggested Baker to Doctor Who producer Barry Letts, who had been looking to fill the part. Letts saw Baker's work in The Golden Voyage of Sinbad (1973) and hired him. Baker would continue in his role as the Doctor for seven seasons, longer than any other actor.
Nicholas Courtney and John Levene reprised their roles as Brigadier Lethbridge-Stewart and Sergeant Benton respectively. Levene had started his role with the Second Doctor story The Invasion (1968) as a member of the military organisation UNIT (the United Nations Intelligence Taskforce). Courtney started earlier in the same year in The Web of Fear, with his character's rank being a colonel. They, along with Sladen, would be the transition cast to carry through from the Third Doctor to the Fourth Doctor, though this would be the only UNIT story for the twelfth season. The Earth-based stories involving UNIT, which had regularly featured in the Third Doctor's period, were introduced partly as an effort to reduce production costs when the series moved into colour by Peter Bryant and Derrick Sherwin, the show's previous producer and script editor, as well as to base the series more on The Quatermass Experiment (1953).
Edward Burnham portrays Professor Kettlewell, the wild-haired, bespectacled boffin who creates the titular K1 robot. Along with Courtney and Levene, Burnham had also appeared in The Invasion, where he played another scientist, Professor Watkins. The part of the K1 robot is played by Michael Kilgarriff who had played another robotic part in The Tomb of the Cybermen (1967), the Cyberman Controller. Patricia Maynard is cast in the part of Miss Hilda Winters, the director of the National Institute for Advanced Scientific Research. Miss Winters' assistant, Arnold Jellicoe, is played by Alec Linstead. Linstead had played the part of Sergeant Osgood—a member of the technical staff at UNIT—in The Dæmons (1971).

### Filming

This was the first serial to be produced for the season. This was also the first Doctor Who serial to have its location material shot entirely on videotape using outside broadcasting facilities, as opposed to the more usual BBC television drama practice of the time of shooting studio interiors on videotape and location exteriors on 16 mm film. This was due to the large number of video effects involving the eponymous robot required in exterior scenes (shot at the then BBC Engineering Training Department at Wood Norton, Worcestershire), which were easier and more convincing to marry to videotape than to film. The team had learned that lesson during the previous season's Invasion of the Dinosaurs. The Wood Norton facility was chosen for location shooting because it had an underground bunker, which director Christopher Barry felt would be suitable for the entrance to the underground complex in the story; however, they were refused permission to shoot in that area.

Robot was the first serial of the twelfth season of Doctor Who. Part one of Robot was first broadcast on BBC One on Saturday, 28 December 1974 and had a viewership of 10.8 million, which was higher than the first serial for season eleven. The next three parts were broadcast over the next successive Saturdays, each having an audience of over 10 million with the exception of the part four on Saturday, 18 January 1975 which only had viewership of 9 million.

### Reception

Viewer reaction was mixed as defined in an Audience Research Report conducted by the BBC. About 30% felt the show was "definitely enjoyable" with a lower percentage being "distinctly unimpressed". A number of viewers thought the new Doctor would "take some getting used to", but most younger viewers gave positive comments about the serial. As with all of the Doctors, Baker received some criticism by the audience, who felt he was a "loony" and presented as "stupid".
Writing for Doctor Who Bulletin in 1988, Jonathan Way felt the serial was fun, and for the same publication, Robert Cope praised Baker's performance as the new Doctor, also noting that the relationship between Baker's Doctor and Sladen's Sarah worked well. David J. Howe and Stephen James Walker, writing in The Television Companion, admired the performances of Nicholas Courtney and Elisabeth Sladen and felt Marter's debut as Harry Sullivan was promising. They also commended the K1 robot costume, but criticised the use of CSO (colour-separation overlay) effects for a number of shots involving the K1 robot, as did Robert Cope. In Doctor Who Episode by Episode, Ray Dexter described Baker's "over-the-top" performance as "compelling" but the plot as "a little lazy and derivative, with some terrible science." He considered the dialogue "some of the best we've seen" but added that "the story falls into the typical Dicks trap of just having baddies being bad because they're bad, and a logical robot behaving utterly illogically". He also thought the location work on video "cheapens the look of the show" and criticised the effects as "not good enough, not even for this era".
Mark Braxton of Radio Times awarded the serial three stars out of five, praising the introduction of Baker and Marter, as well as the K1 concept. However, he felt that the villains were stereotypical and wrote that Robot "boasts perhaps the show's worst visual effect ever". IGN reviewer Arnold Blumburg gave the story a rating of 7 out of 10, attributing its success to Baker. He too criticised the effects, feeling that it made the story "[fail] when trying to present an epic conclusion". DVD Talk's Nick Lyons wrote that it "may not be the most original episode, but it is one of the stronger episodes of the Baker years simply because it never drags and is a breezy action-adventure. It doesn't hurt that the robot itself is a nifty villain". He gave the serial three and a half out of five stars. In 2010, SFX named the scene where the Doctor tries on many different costumes as one of the silliest moments in the show's history.
Reviewing the serial in 2007, literary critic John Kenneth Muir noted several influences on the writing of Robot. Kettlewell's K1 robot is programmed so that it cannot harm humans; Muir traces the inspiration for this directly from the Three Laws of Robotics devised by Isaac Asimov in his 1950 story collection, I, Robot. He also considers the relationship of Sarah Jane Smith with the K1 robot, its transformation into gigantic antagonist (holding a captive damsel in distress, Sarah, in its claw) and its tragic destruction by military force as an analogue of the 1933 film, King Kong.
