Sienna Miller Quits Big Movies

British actress Sienna Miller is quitting big, commercial movies - because they bore her.

The actress has made seven films in the last 18 months, and now claims she has had her fill of them.

She says, "I'm no longer interested in being in big commercial films. I've really begun to avoid more mainstream things."

"I've realised that when I don't play people who are complex and flawed I get very, very bored, and then lazy."
