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.

I mean, the first “Back to the Future” is kind of a perfect script, I think. In terms of handling time travel the best, it depends on your definition. To me, that means it effectively uses it in the story.

Belgrade has kind of a Dublinesque, dear-dirty charm.

The momentum of production keeps you from giving up, so it's really the editing and writing phases where things can look bleakest.

I do think that I'm a big believer in having an idea or having ideas and just tucking them away in the back of your brain. Even if you aren't consciously thinking of them, I think they simmer. You're working on them, even if you don't know you're working on them, and I think having something in your head for a while is a valuable thing.

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.
