I travel abroad constantly on book promotion and research, and the Internet is invaluable to me for accessing U.K. news in places such as America, which most of the time hasn't heard of England.
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.
