The Prediction Fail: Just, y'know, robots and a little thing called the end of the world.

According to the internal logic of James Cameron’s Terminator universe, machines become sentient and bring about a bit of an apocalypse on 29 August, 1997. Then, killer robots stalk the Earth, eradicating any and all human life...

Second follow-up flick (decidedly non-Cameron) Terminator 3 re-set Judgement Day as 24 July, 2004. That one failed to materialise as well. The future’s never set, y’know.

Why We Wish They’d Been Right: Um, we don’t, actually. Unless you’re keen to meet your maker (or some very hard-to-kill metal blokes with glowing red eyes), you’ll be breathing a sigh of relief that this hasn’t happened. Yet.
