Los Angeles, Nov 11 (IANS): Actor Michael Sheen, who is well-known for his portrayals of real-life people in movies, says he can only ever play "himself" on the big screen.

The 43-year-old actor is known for his portrayals of real-life people - including former British prime minister Tony Blair in three films, 'Carry On' actor Kenneth Williams, legendary soccer manager Brian Clough and acclaimed reporter David Frost - in his films but says the characters are just him emphasising different aspects of his personality."

"You're only ever playing yourself. That's all I can play. I think of it like a mixing desk in a sound studio, with all those faders that you put at different level"," contactmusic.com quoted Sheen as saying.

While Sheen has portrayed many real-life stars, he thinks his 13-year-old daughter Lily, whose mother is Kate Beckinsale, would be a great candidate to play him in a biopic because she is such a good mimic."

"My daughter does a pretty good impersonation of me. She's brutal. But you need someone to play you, warts and a"l," he said.
