When I was a kid, I would do stupid things on my bike. I'd jump any ramp, I'd jump over people, I'd jump over things - always crashing, never hurting myself badly but always wanting to take physical risks.

The darker the film, the more vital everyone's sense of humor is on set.

I've had frustrated storytelling juices that have been lying dormant for a long time, and I guess the documentary was a way of me telling a story that I felt most qualified to tell. And I loved it, and I'd love to do something else someday, probably more narrative-based. But I'm in no rush.

Definitely the script because you want to be part of an interesting story, you want your character to be a challenge, then comes the director. But essentially it's the script first and whether it's a character that you think you can do.

I think quite often, being on the new set is not what you expect. The most serious film can be the most fun. The one that's supposed to be fun can be the most serious. I don't think there are any hard-and-fast rules. I just think it really depends on your director and what the general vibe is.

Abs are for people with no friends.

I've given no thought to moving to America at all.
