Unlike some of the time-travel movies I love, like 'Primer' or '12 Monkeys,' 'Looper' is not about time travel. It's about this situation that time travel creates and the people dealing with that situation. So narratively, the big challenge was to have time travel get out of the way.

My favorite sci-fi always uses its hook to amplify some bigger theme or idea - some emotional thrust.

In almost the same way you know what your grandmother looks and sounds like, you know what Bruce Willis looks and sounds like.

You come out of each movie just thinking, "God, if we can fool them into letting us make just one more, we can get it right."

Even if I had $200 million, I’m very wary of overusing CGI. I think it’s a great tool and it can be used really effectively, but I feel like it does tend to be overused and especially in sci-fi stuff.

Memory is a form of time travel. That's something we do during the course of the day, every single day. The idea of actually being able to physically adjust that and change it instead of being haunted by it is a really human thing.

Writing sucks. I think it's terrible. Writing is not fun, and don't trust anyone who claims to enjoy it. Liars!
