Some things are just really difficult to do. That's what I find hard. I usually can find a way to do a character to make it real and work. But sometimes it's a struggle sustaining that, because there's such a level of personal involvement and personal, physical, and emotional distraughtness.

I like the tragedies way more than the comedies because they're so universal.

It's exciting to be with really, really good people. Some people make you feel like you've got to up your game. Working with good people is always good.

So the experts think we could have an AIDS-free generation in Africa by 2015, even if the mothers are positive.

Kids are more genuine. When they come up and want to talk to you, they don't have an agenda. It's more endearing and less piercing to your aura.

I actually find in America, there's a slight snobbery about actors who go back and forth between big heavy dramas and popcorn fare. That always intrigues me, because that doesn't exist in the same way in Britain. And I imagine it would be worse. In terms of the sort of class, and the sort of snobby, slightly on the back-foot thing Britain has. But it's much more prevalent in America. I'm really intrigued by it. I don't know why that is. But I'm aiming to break down those barriers by being in a Shakespeare film and a Smurfs film within six months of each other.

I think American actors are much more intimidated by Shakespeare.
