To me, acting is very therapeutic. I get out a lot of anger and frustration. It's maybe hard to believe, but as a kid I really had a lot of self-doubts. My father was very ill - he was an alcoholic - so there were a lot of things that built up for me. And because I was going to a Catholic school in a small German town, a lot of it was suppressed. I was angry and didn't know how to get it out.
