10 Movies That Didn't Know When To End

8. Source Code

I know what you're thinking - "but wait, isn't Source Code only 93 minutes long?". Indeed, you're not wrong, but even short films can go on past their expiration date, and Duncan Jones' ambitious, thoroughly engaging sci-fi flick had a fantastically ambiguous departure point several minutes before the end, but couldn't resist going a little further with it. After Capt.

Colter Stevens (Jake Gyllenhaal) realises the true nature of his situation - that his mind is simply hooked up to a computer, as his body has been mutilated beyond repair in the war - and manages to provide the authorities with enough information to capture the train bomber they're after, he returns to the source code one more time.

This gives Stevens 8 minutes before his life systems will be terminated, and as the time runs out, he goes to kiss Christina (Michelle Monaghan), at which point everything freezes, as this scenario has essentially been "severed". However, things promptly unfreeze, as it appears that Stevens has managed to create a parallel universe in which his mind and body are free to live a normal life; it's a nice idea, but a little too happy - the freeze-frame ending would have been perfectly melancholic.
