[[folder: "Doctor Who is required- What? His name ''isn't'' 'Doctor Who'? Well, it's too late to remind me ''now!'' We already used up all the retakes the studio is allowing!" ]]
[[note]] Early ''DW'' was mostly shot live in one go because retakes were difficult to manage back in TheSixties. Hence a lot of identifiable production errors, like misread lines, especially from Creator/WilliamHartnell (in his case, nicknamed "Billy fluffs"). [[/note]]]]

->''"I dig your fab gear!"''
-->-- A nightclub owner likes the Doctor's clothes.

The one where he actually is "Doctor Who".

The TARDIS arrives in contemporary London, and the Doctor and Dodo visit the Post Office Tower, where they meet Professor Brett and his new super-computer WOTAN, which can think for itself and is about to be plugged into a worldwide computer network.

[[AIIsACrapshoot I think we can all see what's about to happen here, can't we?]]

WOTAN decides that machines are superior and should rule the world, and hypnotises humans into building the titular War Machines, which turn out to be more than a match for the army. The Doctor uses a magnetic field to capture one, which he then reprograms to destroy WOTAN.

Dodo, having been hypnotised by WOTAN, decides she's had enough adventure. Since she's back in her own time, she decides to stay there. In one of the lamest departure sequences for any companion, she [[DroppedABridgeOnHim isn't seen after episode two and says goodbye to the Doctor in episode four via a note, delivered by Polly]]. The Doctor leaves, but not before Professor Brett's secretary Polly and able seaman Ben Jackson enter the TARDIS while trying to return a missing TARDIS key to the Doctor.

* AIIsACrapshoot
* BringNewsBack: Ben escapes to tell the Doctor and others what WOTAN does.
* CelebrityResemblance: When the Doctor arrives at the Inferno club, Polly comments that he "looks a bit like that disc jockey". Presumably she means Creator/JimmySavile, which makes it a [[DepravedKidsShowHost somewhat unfortunate comment]] now...
* CharacterAsHimself: For the first three episodes, WOTAN is listed last under the cast as a cast member playing 'himself'.
* ComplainingAboutRescuesTheyDontLike: Ben tells a man to stop hassling Polly, he starts a fist fight with Ben, and Polly complains -- though Dodo intervenes on his behalf.
** Though to be fair, he did tell her "be careful who you encourage" - implying it was [[ValuesDissonance her own fault]] she was harassed by that fellow.
* ComputerEqualsTapeDrive: Not only WOTAN but the War Machines have these -- the latter are mounted on the outside where they can easily be damaged by gunfire!
** Justified in that the story was set in 1966.
* DamselInDistress: Mind control effects on two women. (Plus the man who wouldn't leave Polly alone at the nightclub.)
* DisposableVagrant: A bum tries to sleep in an abandoned building, unaware that WOTAN is using it to construct one war machine.
* DistressedDude: Most of the mind control victims are men. And Ben gets captured and forced to work without it.
* {{Dropped a Bridge on H|im}}er: Dodo.
* TheDulcineaEffect: Ben fights for Polly rather quickly.
* EstablishingCharacterMoment: Polly is introduced privately pulling a silly face to make fun of her nagging sexist boss, and quickly turning it into a forced smile before looking around. Ben is introduced moping in a bar, beating up a man who sexually harasses Polly, and then blaming Polly for the assault.
* FiveRoundsRapid
* ForHappiness: The bartender asks Polly to help cheer up Ben. Polly comments on how reliably she is called on for such measures.
* AFriendInNeed: Ben is first persuaded to act when he sees Polly being hassled at the nightclub.
* IdiotBall: Plenty from WOTAN -- its hypnotised slaves work like machines until they drop (WOTAN should know that the inefficient humans require regular food and rest) and it tries to take over London by brute military force instead of [[Series/AForAndromeda using its role as an advisor to the government to manipulate events]].
* InHarmsWay: Ben is morose because he's on shore duty.
* LandmarkingTheHiddenBase: The Post Office Tower serves as the villains' HQ.
* MasterComputer: WOTAN, which is similar to [[Franchise/TheTerminator Skynet]] but, this being The '60s, it consists of a single Master Computer based in the Post Office Tower in London.
* MindRape: Dodo gets hypnotised by WOTAN, necessitating the First Doctor to hypnotise her back to normal. Since Dodo quits afterwards, only giving a second-hand goodbye through Ben and Polly, some fans speculate (especially in light of the scene that went on between the Tenth Doctor and Donna) that the Doctor actually wiped her memory, or else influenced her to leave for her own perceived safety.
* NewscasterCameo: Real-life newsreader Kenneth Kendall plays himself in news reports about the War Machines.
* ThePowerOfFriendship: The mind-controlled Polly clearly sees Ben escaping, and says nothing. When someone asks after him, she explains, but when he asks her why, she does not know, and after a moment, starts to remember that he had been her friend.
* PutOnABus: Once Dodo is freed from WOTAN's influence, she's removed from the plot. In the second episode. And in the most perfunctory way possible: the camera just pans right off her onto the Doctor in mid-scene, and she's never seen again; her decision not to return is briefly described second-hand several episodes later.
* RealLifeWritesThePlot: Midway through production, Jackie Lane's contract expired, hence Dodo's sudden departure.
* RippedFromTheHeadlines: The story focuses on the newly-built and cutting-edge technology of the Post Office Tower, as well as theoretical new concepts like computers all over the world linked together via telephone lines (which of course is presented as the computer ringing people up to talk to them with words).
* TheSixties: Remember when [[AlternateHistory that computer took over the world]]?
* StayInTheKitchen: Polly is constantly told to stay out of the computer science and go and make coffee.
* TinCanRobot[=/=]KillerRobot: The War Machines.
* WorstNewsJudgementEver: The death of a tramp makes the front page of ''The Times''. Actual deaths in 1966 included writers Creator/EvelynWaugh and Creator/CSForester, actors Creator/BusterKeaton and Creator/MontgomeryClift, comedian Creator/LennyBruce and Captain Cook's 200 year-old tortoise. Their deaths did not make the front page of ''The Times''.
* YouHaveFailedMe
* YouShallNotPass: Episode 3 ends with a war machine bearing down on the army and random civilian director-type-people. They all turn and run for cover, but the Doctor stands his ground.
