(about his role as Tigris in "Gladiator")
Sven: It was one of the toughest jobs I've ever had in my life, because we had every scene choreographed and storyboarded. And there was three and a half weeks of rehearsal, 10 hours a day, with a stunt-double, with Russell Crowe, with the tigers, with a sword, with an axe, with a mask, with a 50 pound uniform... It was very complicated.
(after being asked what he thinks of his friend Arnold Schwarzenegger becoming governor)
Sven: This is very exciting for America, for California and the whole world. For a non-politician coming in with the common sense, and as a business man trying to make California profitable again, and a state of big business... well, he's the man to do it. Especially when you are financially independent, you can hire all the right people. When he goes in for something like this, he goes in 100%!
I went with him on several of his campaign tours and I am very proud of him. He's going to do extremely well. I think people are in for a surprise. He's not only a poster boy , he's a guy that is committed, he's a guy that can motivate and get people to work harder. People are going to be surprised by his stamina and his work ethics. People are going to be surprised; he sounds funny, he has a funny name, he is a body builder, he's an actor, he's this and that... so I think Arnold is going to be the people's politician and champion. I can not see anyone who would be better Governor for this state. I am fully behind him.
