Stewart, Joan Jett 'share cinema passion'

Kristen Stewart has revealed that she shares a passion for cinema with Joan Jett.

The actress, who portrays the rocker in The Runaways, has said that she had to study Jett by watching footage of her as a teenager and realised that they both loved the art of film, reports Contactmusic.

Stewart said: "I watch a lot of '70s movies. I love all of Stanley Kubrick's movies. I love old independent movies like John Cassavetes's movies.

"Joan was watching funny stuff when she was younger. There's this tape of her when she's 14 so I could hear how she spoke, and it's so different. Now she's very New York and raspy, but back in the day she was light; she was a kid and she just talked about a movie that was funny."

She added: "She completely understands where I'm coming from. I mean, we're both fairly, unabashedly ourselves, so the advice sort of stops there, do you know what I mean? She says, 'Just be real, just say what you mean'."
