->''"This is the voice of world control. I bring you peace. It may be the peace of plenty and content or the peace of unburied death. The choice is yours: Obey me and live, or disobey and die."''
-->-- '''Colossus'''

'''''Colossus: The Forbin Project''''' is a 1970 science fiction film based on a novel of the same name.

[[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.
* 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.
* 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's exact specifications. And you thought your old Speak and Spell sounded creepy...
* 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.
* 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.
* 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.
* {{Expy}}: The president is ''very'' Kennedy-esque.
* GoneHorriblyRight: The government built Colossus to help prevent war. Be careful what you wish for.
* GovernmentConspiracy: The Russians cover up the destruction of a city by Colossus's ICBM as a pipeline explosion.
* 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.
* 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.
* 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.
* SelfGuardingPhlebotinum: The titular MasterComputer's main defense is that it was built inside its own radioactivity spewing nuclear reactor.
* TakeOverTheWorld: Colossus and Guardian unite into a single system and rule the world to keep humans from destroying themselves.
* ThereIsAnother: During the initial unveiling of Colossus, it alerts the operators that "There is another system".
* TwentyMinutesIntoTheFuture
* 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.
