The Day the Earth Stood Still (1951)
Michael Rennie confounding puny Earth scientists with his knowledge of astrophysics and impressing smalll boys with diamond currency is really just a side show to the real star of the movie – Gort. Yes, he may just look a little like a man in a rubber suit now, but he terrified a generation.
The Black Hole (1979)
Forget that cute little V.I.N.CENT. robot – the one you really wanted to command was the evil Maximilian, an imposing, levitating mute armed with lasers and hand blenders.
Okay, maybe it's more an alien movie than a robot flick, but Bishop is still one of the most famous 'bots to grace the silver screen. The freaky knife trick was emulated by kids around the world – mostly using blunt pencils and other non-threatening implements.
Forbidden Planet (1956)
Robby the Robot, with his twiddly antennae, flashing lights and synthetic voice, undoubtedly stole the show from a young Leslie Nielsen and the oddly unscary (once you saw it) Id monster.
Every kid wanted to be a robot after they saw D.A.R.Y.L. (Data Analysing Robot Youth Lifeform) kicking arse at Pole Position on the Atari and hitting 'em way outta the ballpark. Shame he was such an irritating, humourless little git. And he got to fly an SR-71 Blackbird, damn him.
