I knew very little about Rugby. But, I think it helps in terms of an American audience the game is enough like football in that it's a battle for field position and you score by running into what looks a lot like an end zone. I think in terms the nuance of the game, Americans won't get that stuff. I think in terms of the peanut butter and jelly version of what you need to know, I think it's pretty clear.

Still, the change is nearly indescribable - going from total obscurity to walking down a street in New York and having everybody turn and look; to feel the temperature of a room change when I walked in.

If anybody wanted to photograph my life, they'd get bored in a day. 'Heres Matt at home learning his lines. Here's Matt researching in aisle six of his local library'. A few hours of that and they'd go home.

The danger of course is always is caricature. The biggest challenge was to sound like Nelson Mandela. Everything else is easy to do, walk like him. He has a few ticks and things I noticed that I picked up. I didn't have any agenda, as it were, in playing the role other than to bring it as close to reality as I possibly could.

If your movies don't perform, they just stop calling you.

Maybe if we sit out for the next few years and let Clint Eastwood get a little experience, he's going to be a good director.

I think what makes a good actor's director is somebody who understands what I'm doing and is respectful of it, but who also has a vision and is directing me toward their vision in a way that feels productive.
