Listen, acting is not surgery, it's entertainment. You're doing something to hopefully move people, to make them laugh, to transport them. But actors are vulnerable, and the reason we're vulnerable is that we're always trying to recreate human behaviour.

Actors who perhaps are super-confident and have absolute belief in themselves I always admire, because I can't really be like that.

As an actor there's a lot of scrutiny and, even when you've had success, it becomes about sustaining that success. A friend of mine described it as a peakless mountain. Even for Robert De Niro there's Al Pacino and for Pacino there's De Niro.

Learning lines is hard for me because I have the attention span of a six year old. That's why being on planes all the time is so useful - I'm forced to learn out of boredom.

And you can't complain about kissing Emma Watson. Isn't that what everyone in the world wants to do? I've known Emma for a few years. She's this amazing capacity of young and vibrant and brilliant, but also a bright, intelligent old soul.

I'm trying to buy a house and set some sense of roots because otherwise you're constantly chasing one job after another, and you look back and you've had all these very extraordinary experiences with extraordinary people, but there's not a line of continuity to it.

This is the great luxury of not working: the moment you read a book that has nothing to do with work, you know you're really relaxed. And I have a sh*t attention span. I can't concentrate for more than five minutes.
