Kristen Stewart Takes Role Where She'll "Look Like A Porn Star"

The pale-skinned "Twilight" star will get a tan and dye her hair blonde before shooting the edgy thriller, "Cali," with director Nick Cassavetes. She tells Women's Wear Daily, "I'm going to get into the best shape of my life. I'm going to look like a stripper. I'm going to look like a porn star."

Stewart will play Mya, who flees Los Angeles with her boyfriend after selling a snuff film, but returns years later to save her sister when she gets into trouble. The 22-year-old actress admits she was intrigued by the "extreme in every way" script and hopes she can come to grips with her character's psyche.

She says, "A lot of times, you'll read a script and you can identify with things that are very surprising, things that kind of shock you about yourself. And the process of making the movie is finding out why those feelings occurred. Sometimes they're not always easy to define ... (But) if you don't know why someone is the way that they are, then you're just playing a caricature of a girl."
