I would absolutely like to play more leading roles. There's no philosophy - well, the only philosophy, I suppose, is to try and do different things.

Certainly for my father, there were great times, good times, not-so-good times. He might be shooting a Fellini film for six months, then not working for two months. I'm used to that dynamic.

Every now and then, they ask me to come in and improvise with Stanley Tucci for an afternoon. They fly me off to America, I improvise for an afternoon - it's not the hardest, most taxing job.

I'm a politician. I run for office. That's my profession.

You just try to absorb as much as you can from someone who has won as many races and championships as he has. Career wise, he's been the greatest thing that's happened to me.

No matter what happens to me and my career in the future, Berlin is always going to be my hometown.

What's important about me is that I really have, in ways I never could have foreseen when I was young, a writing career that's reached a lot of different places.
