It's the apocalypse, and you can only save three films. Which ones?

Hmm, I think this is one of those that you could think of a different three everytime but the ones that spring to mind now are

The Good the Bad and the Ugly
The Shawshank Redemption
Avatar

So many others I would like to give a mention to but everyone else has stuck to the rules and come up with three, so I will too!
