Giamatti: I play the weird freaks
Paul Giamatti has said the film roles he takes have helped him to keep his personal life private.
The actor stars in Parkland, which follows events at the hospital where staff tried to save JFK on the day he was shot, alongside Zac Efron, and explained how he escapes the media scrum that follows his young co-star.
He said: "I think it begins with the fact that I don't look like that guy. I don't want to put that on [Zac] as some kind of thing but it certainly helps to have people wanting to take pictures of you if you're a handsome young man. Nobody really cares about me on the beach in my bathing suit."
Paul, 46, added: "It's a lot to do with the characters you play, the personas people put on you. If you're always playing sexy whatever, then people think, 'Oh, he must be sexy whatever.' I don't play sexy whatever, I play weird freaks, messed up people.
"I don't think my persona is perceived as, 'Wow, can't wait to follow this guy around, he's going to be leading a really action-packed, interesting life'."
The Sideways star said he also makes an effort to stay below the radar for the sake of his career.
He said: "I'm interested in preserving my ability to play different characters. I don't want people to know very much about me or I wouldn't be able to do what I do for a living. The second you start acting in movies it starts getting f***ed up for you, people start recognising you.
"It was easier when nobody knew who I was, so I could go on the subway and watch people. Now, people are watching me on the subway and it's a bummer because I can't spy on them because they're spying on me. But I'm still going to do it, I'm not going to stop spying on them."
Parkland is released in cinemas on November 22.
