I was flying by myself from about four or five years old. I was raised in Frankfurt and I would fly to my grandmother's in Munich almost every weekend. I really enjoyed it; I always had really lovely stewardesses looking after me.
A family friend took me to LA when I was 15 and I just fell in love with it. It was in the winter but there was sunshine and I remember coming out of the airport and thinking, 'I never want to leave'. I moved there when I was 18 and stayed for several years.
I'm a horrible over-packer; I pack everything. I went on a trip with two friends to Thailand and brought a leather jacket and heels — we stayed in a beach hut and of course all I was wearing were sarongs.
If I could live anywhere in the world I'd stay where I am now — London. I love the fact that you have everything here; the best theatre, fantastic art exhibitions and concerts, and you can be anywhere in Europe very quickly. My father lives in France and my mother in Germany, so I can just jump on a plane and be with them, which was hard when I lived in LA.
For getting away from it all, I really love Israel. The culture, the people, the food is phenomenal, the beaches are great and the nightlife is fantastic. I have a really good time every time I go out there.
I tried sushi for the first time in New York when I was about 12 or 13 and it was the most exotic thing I had ever eaten. Coming from Germany, it just wasn't around — I grew up with Wiener schnitzel, sausages and Sauerkraut. I still love all that comfort food though; I love a roast here because it reminds me of German food.
I've been to India very briefly, but I really want to go back and have a long holiday in there. That's definitely a dream of mine. As an actor you can take some time off — not always a good thing — and maybe this winter I'll take some time to travel India.
