Michal Sheen doesn't want to do the same job "over and over again".
The 'Twilight Saga' actor loves working in Hollywood because it means he never has to repeat the same thing twice if he does not want to, and is happy to try "quite hard" to give himself options.
He said: "What's enjoyable for me, as an actor, is to do as many different things as possible. It challenges me, as an actor.
"You don't want to get into doing the same thing, over and over again. I know I don't. I've worked quite hard to give myself those options, I suppose. In terms of building a career and having longevity, that's good."
In vampire series 'Twilight' Michael portrays evil character Aro, a role he relishes because he gets to play someone "completely insane".
He added to Collider.com: "What I love about that character is that I think he's totally insane. "Immortality - living forever - has driven him completely insane, or certainly into an area of sanity that is not really accessible to most people, and yet, part of his insanity is that he thinks that he's a sentimental, little old lady. He thinks he's this cuddly grandmother, somehow."
