9 Movies You Didn't Realise Stole Their Endings

9. Alien 3 Stole... The Incineration From Terminator 2

The Ending: In an attempt to stop the series turning into a recurring case of Ripley waking up to ever-increasing terror, Alien 3 decided to end the story (or at least mean any follow-up would be ridiculously convoluted).

Sigourney Weaver's action hero discovers she's been impregnated by one of the titular creatures, so to avoid the perfect organism falling in the hands of the evil company throws herself into a convenient lava pit.

Where You Saw It First: Realising the first film was overwhelmingly depressing, James Cameron gave Terminator 2: Judgement Day a less apocalyptic finale, with the characters successfully averting the machine uprising.

It's a tad bittersweet, however; the T-800 who befriended once-but-not-future-anymore revolutionary leader John Connor must be destroyed lest his technology inadvertently lead to Skynet's rise. They do this by dropping him into a convenient molten metal pit.

The films came out within a year of each other, but that doesn't mean there isn't some light borrowing going on; Alien 3 had a notoriously troubled production, but it's likely that an idea first floated during Cameron's previous involvement in the franchise (he directed Aliens), could have stuck through because, well, it is a cool idea.
