There's a plethora of wonderful documentaries. I made a point of not looking at anyone else's portrayal of Henry because I think it would have been too confusing - so I've got a lot of films to look forward to.

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.

Throw your children in the surf and let them get used to it. They have to learn all about rips and tides and swimming between the flags and all that sort of stuff. I know that sounds ridiculous but it's true.

It only seems jarring when you look back on the work I've done. I think if you had to map that out at the beginning and you said, "Right, sit down, this is what you're going to be doing," you'd probably freak out. But I'm someone who really enjoys not being himself. So if you consider that, then it all sort of makes sense. And I just think that's the job of an actor. I guess that's the variation that you're talking about. It's probably a byproduct of just constantly looking for something different, because that's what I feel like I'm supposed to do.

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 longer you have something, the stronger the bond. That's true with people as well as things.

I hate being clean-shaven. My daughter gets very upset if I shave and says, 'Bring back the spikes, Dad.'
