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.

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

Hopefully with each thing that you do you're learning something, you're growing, and you're pushing yourself a little harder in some way or another. So I think you'd be in real trouble if each new thing that you create didn't feel like 'Oh, wow. I feel like I'm doing something a little different this time.

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.

All my favorite movies are somebody else's least favorite movie.

I just don't think CGI is up to manipulating the human face yet. I feel like you can get away with it with aliens or monsters or something that's intentionally foreign, but I have yet to see anything digital to do with the human face that doesn't just look ridiculous.
