Unlike some of the time-travel movies I love, like Primer or 12 Monkeys, Looper is not about time travel. Its 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. – Rian Johnson
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. – Rian Johnson
