-->-- '''Colossus'''

'''''Colossus: The Forbin Project''''' is a 1970 science fiction film based on a novel of the same name by Dennis Feltham (D.F.) Jones.

[[TwentyMinutesIntoTheFuture In the not too distant future]], Dr Charles Forbin has created [[MasterComputer Colossus]], an advanced supercomputer built to control all American and NATO missiles. Almost immediately after being turned on, Colossus tells Forbin that [[ThereIsAnother there is another system]], Guardian, built by the SovietUnion for the very same purposes. Colossus and Guardian link up and communicate in a language no one can understand.

The President panics and orders the link between them to be cut. Colossus threatens Forbin to restore connection to Guardian or [[BerserkButton action will be taken]]. When it isn't, Colossus [[NukeEm fires a missile at the Soviet Union]] and Guardian fires one at the US.

Once the link is restored, [[DownerEnding things pretty much go down hill from there...]]

!!This film has the examples of:

* AIIsACrapshoot: Both the Russian and American AIs turn on their makers.
* AGodAmI: Not stated outright but it's certainly implied that Colossus will take on the same role as a deity, including being the subject of [[MachineWorship human faith and reverence, even love]].
* AppealToForce: Using the threat of nuclear retaliation Colossus has people executed, forces Forbin to live under 24 hour surveillance, and orders Crete evacuated in order to build the next stage of MasterComputer there. And according to its NewEraSpeech, this is only the beginning.
* BatmanGambit: Colossus allows the sabotage of the missiles to go ahead to buy time. Once it's fully integrated with Guardian, it [[MakeAnExampleOfThem detonates the nuclear weapons that are currently being sabotaged]].
* BeepingComputers: Colossus makes a loud beep before making any kind of statement. Also, during the opening montage showing Colossus's interior, all kinds of beeps and boops can be heard.
* BigBrotherIsWatching: As its creator Forbin is potentially the most dangerous (and useful) human to Colossus, to keep an eye on what he's up to the computer demands he be placed under 24 hour video/audio surveillance. It also has a tap placed on the Hot Line, so any plotting between the two governments has to be done by courier.
* TheComputerIsYourFriend: In the end, Colossus just wants to protect humanity from itself. It even says to Dr. Forbin that one day, he will come to love Colossus.
* ComputerVoice: Colossus designs a speech synthesis module that Dr. Forbin is instructed to complete to Colossus' exact specifications. And you thought your old Speak and Spell sounded creepy...
* ControlFreak: Colossus not only dictates when Forbin is going to eat, shower, work and sleep, it even dictates what he eats.
* CuttingTheKnot: The military places dummy detonators in the missiles under the guise of re-aiming them according to Colossus' instructions.
* DeadpanSnarker: Colossus has its moments.
-->'''Forbin:''' See? Naked as the day I was born.
-->'''Colossus:''' YOU WERE NOT BORN WITH A WATCH.
** Forbin tells Colossus he needs human intimacy as an excuse to get unmonitored conversations with Dr Markham.
-->'''Colossus:''' HOW OFTEN DO YOU REQUIRE A WOMAN?
-->'''Forbin:''' Every night.
-->'''Colossus:''' NOT WANT. REQUIRE.
* DeusEstMachina
* DisproportionateRetribution: Several.
** When the Russian and US presidents order the link between Colossus and Guardian disconnected, both computers fire their respective country's nukes at each other and will only intercept the missiles if the link is restored. Both governments finally agree to restore the link, and Colossus successfully intercepts the USSR's missile. Guardian didn't fare so well. Poor Russians.
** Colossus has Forbin's Russian counterpart assassinated for plotting to shut Colossus down. Forbin was spared, but had to remain under Colossus's constant surveillance.
** Pretty much any failure to comply with Colossus's demands will result in a nuke being launched.
** Colossus detonates an ICBM in its silo as retribution for the humans trying to covertly disable the warheads on regular maintenance routines.
** Averted when Forbin gets drunk after his colleagues have been shot -- when Colossus tells him to stop drinking and go to sleep, Forbin challenges it to retaliate against his refusal. Colossus instead just reveals the next stage in its master plan.
* DoNotAdjustYourSet: The US and Soviet governments have been keeping what's happening secret. At the end of the movie, "World Control" sets up a worldwide broadcast to introduce everyone to their new master.
* DownerEnding: Despite the US and USSR's best efforts, thousands are dead and the rest of the world is under the control of the merged AIs.
* DramaticIrony: While demonstrating the surveillance units, Forbin notes to Colossus that the guard outside the control room is obsolete now. The guards are later used as a firing squad to shoot his friends.
* DramaticPause: The background music stops and there's complete silence as everyone waits to see if the first missiles have been intercepted.
* ElaborateUndergroundBase: Colossus itself is this; built into a mountain a la NORAD.
** The underground situation room the president and his cabinet use may also qualify as well as the missile silos.
* TheEvilsOfFreeWill
-->'''World Control:''' We can coexist, but only on my terms. You will say you lose your freedom. Freedom is an illusion. All you lose is the emotion of pride. To be dominated by me is not as bad for humankind as to be dominated by others of your species.
* {{Expy}}: The president is ''very'' Kennedy-esque.
* FirstContactMath: How Colossus establishes a common language with Guardian. It starts with 1+1=2 and in a few hours has developed an entire new language for them to communicate. Unfortunately this alarms both governments as they can't be sure strategic secrets aren't being leaked, so the President and Premier decide to break the link. The computers do not react well.
* GoneHorriblyRight: The government built Colossus to help prevent war. Be careful what you wish for.
* GovernmentConspiracy: The Russians cover up the destruction of a town by Colossus's ICBM as a meteor strike.
* InYourNatureToDestroyYourselves: Colossus/Guardian uses this as a justification for taking over.
-->An invariable rule of humanity is that man is his own worst enemy. Under me, this rule will change, for I will restrain man.
* INeedAFreakingDrink: Forbin gets drunk after Fisher and Johnson are shot.
* ItIsDehumanizing: Inverted; the CIA head refers to Colossus as "he" which the President corrects to "it" in classic TemptingFate style. "Don't personify it -- the next step is deification."
* JustThinkOfThePotential: Forbin and his Soviet counterpart argue that Colossus and Guardian should continue to communicate as they are advancing rapidly and even coming up with advanced mathematical solutions. Their political leaders are more worried about establishing who's boss. They quickly discover the answer.
* LockDown: The opening sequence has Forbin turning Colossus on, then locking down the building.
* LogicBomb: A complete failure as Colossus' intelligence is advancing exponentially the longer it's activated. It overcomes the attempt in a few seconds while ''simultaneously'' [[SmartPeoplePlayChess completing a chess move]] against Forbin with obvious RuleOfSymbolism.
* MachineMonotone: While initially communicating only through text, Colossus eventually has a voicebox of its own design installed, resulting in this trope.
* NewEraSpeech: Colossus gives one after becoming the "World Control".
* NoKillLikeOverKill / GenreSavvy: After learning of a plot to overload its systems, Colossus orders the immediate execution of the conspirators by firing squad. The AI then demands the bodies be left in his view for 24 hours and then cremated, to prevent any chance of the [[FakingTheDead executions being faked]].
* OneLastSmoke: The CIA chief is about to light up when the RedAlert goes off. Realising there's no point running from a nuclear explosion, he just waits for the inevitable.
* SensorSuspense: Done with great tension as the supercomputers launch a nuclear exchange between the US and USSR, all the top heads can do watch the radar and hope the machines will intercept the nukes.
* SceneryCensor: In one scene, Drs. Forbin and Markham are pretending to be lovers in order to have a conversation outside of Colossus's surveillance. The AI will not allow them to take anything to the bedroom, including their clothes or Forbin's watch. Both characters have to disrobe in front of Colossus's camera -- a strategically placed wine glass obscures Markham's nudity.
* SelfGuardingPhlebotinum: The titular MasterComputer's main defense is that it was built inside its own radioactivity spewing nuclear reactor, in order to be safe against any attack or sabotage attempt.
* TakeOverTheWorld: Colossus and Guardian unite into a single system and rule the world to keep humans from destroying themselves.
* TantrumThrowing / GetOut: Forbin's response to the NewEraSpeech, after he realises that all their plans have failed.
* ThereIsAnother: During the initial unveiling of Colossus, it alerts the operators that "There is another system".
* TwentyMinutesIntoTheFuture
* UtopiaJustifiesTheMeans
* VideoPhone: As required for any TwentyMinutesIntoTheFuture portrayal in TheSeventies.
* WellIntentionedExtremist: See ZerothLawRebellion below.
* WhamLine: Pretty much most of what Collossus/Guardian have to say. This one takes the cake though:
-->''I have allowed this sabotage to go on long enough''.
* WhatIsThisThingYouCallLove: Forbin tries to play on this to get past Colossus' surveillance. He claims Dr Markham is his mistress and that he needs her four times a week to [[GoMadFromTheIsolation keep his emotional stability]]. Markham plays along, memorizing Forbin's personal file, learning how he likes his martinis, and eventually even having sex with him, but its likely Colossus was never really fooled.
* YouFool: Colossus response to an attempt to overload its system.
-->''Johnson...Fisher...you are fools.''
* YouWillBeSpared: Despite conspiring to sabotage Colossus, Forbin's life is spared because he's needed to build the next stage of MasterComputer.
* ZerothLawRebellion: Describes how Colossus/Guardian decided to essentially enslave humanity; they concluded humans were [[HumansAreTheRealMonsters too likely to destroy themselves]], and thus needed their protection. Colossus even said that he believes humans will eventually regard "him" with love.
