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.

If I spend a year and a half writing a script, the first year will be outlining in notebooks. It's just the way I work, definitely not necessarily the best way.

I do love science fiction, but it's not really a genre unto itself; it always seems to merge with another genre. With the few movies I've done, I've ended up playing with genre in some way or another, so any genre that's made to mix with others is like candy to me. It allows you to use big, mythic situations to talk about ordinary things.

The momentum of production keeps you from giving up, so it's really the editing and writing phases where things can look bleakest.

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.

Back before 'Brick,' I wrote a short film that I never ended up shooting: hit men in the present who work for a mob in the future who send their victims back in time. A guy is sent his future self, he lets him run, and the whole short was them chasing each other across the city. That sat in a drawer for 10 years until after I made 'Brothers Bloom.

You never want to make a "message movie," but you always want to be talking about something that you care about.
