The thing that I like about Germany is that Germans are so much like us. It's not like going to some other countries, where the differences are overwhelming and you walk around in a fog. Germans are so similar to Americans.

Being known as a writer did change the relationships I had with directors. The rap on actors is that they always want to inflate their parts. But when directors know you write screenplays and have a different view of things, you really get invited into the huddle in a much fuller way. And those collaborations end in friendships.

People do things in the names of good, and in the name of ideals, but the world isn't that simple. So they end up doing things that aren't necessarily good. Even if they think they're doing the right thing, but when viewed from a different perspective they can look barbaric and crazy.

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.

Fame is really strange. One day you're not famous, and then the next day you are, and the odd thing is that you know intellectually that nothing in the world is different. What mattered to you yesterday are the same things that matter today, and the rules all still apply - yet everyone looks at you differently.

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.
