I never met anybody in my life who says, I want to be a critic. People want to be a fireman, poet, novelist.
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.
As a child, I didn't know what I didn't have. I'm thankful for the challenges early on in my life because now I have a perspective on the world and kind of know what's important.
