It's tricky. I've never been standing at the top of the tree with tons of money thrown at me. I've never really had a profile. So in a way I have this 'nothing to lose' attitude.

One of the things I've always enjoyed is moving around and staying fit. Physicality is such a big part of being an actor, but it's also about stillness and silence.

To act with a tennis ball and imagine it's a tentacle, or if you're in some kind of wilderness film and you go, 'Okay, we can't have a grizzly bear here, but imagine when you step over the rock there there's a grizzly bear.' I don't know. They're tough moments.

Every job leaves its residue, a bit of extra knowledge, a new skill-set.

When people are really great at what they do there is no aggression because they are comfortable in their own skin. They know themselves well enough that you don't have anything to prove.

Whenever you deal with science fiction you are setting up a world of rules. I think you work hard to establish the rules. And you also have to work even harder to maintain those rules, and within that find excitement and unpredictability and all that stuff.

Basically you want as many people as possible to see your movie.
