That's part of the appeal of time-travel movies: The notion of going back and fixing something.

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

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.

My filmmaking background has really just been making movies with my friends since I was 12 years old. That's how I feel I learned how to tell a story visually, by just going out with a video camera and making movies with my friends and family.

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 really spend as long as I can sketching everything out and working on the structure before I sit down to type out scenes.

I'm a sci-fi fan, and I guess you have to let go of some of that at some point, and realize that as long as you're focused on telling a story that you care about, at the end of the day, that's what really matters, even to hard-core sci-fi fans.
