Kristen Stewart on Jett challenge
Kristen Stewart has admitted it was a challenge playing Joan Jett in her latest film.
The Twilight actress stars as the 1970s rock star in The Runaways, the name of the singer's first band.
Kristen said at the Sundance Film Festival: "Everybody knows Joan Jett, but nobody really knows how hard it was to become her - we've grown up being told that we, us girls, can do whatever we want, and that just wasn't the case for them."
Joan herself said at the press conference ahead of the film's premiere on Sunday that it was a difficult environment for girl bands to be successful.
"It was initially kind of laughing, like that kind of smiling, going, 'What are you doing? You can't do this. Girls don't play rock 'n' roll.' And when they saw were really serious about it, the attitude kind of changed," Joan, 51, said.
"Anything from really just insulting and dirty, nasty things. Calling us names, every name that you can call a woman. Just stupid things. Bands feeling threatened by us.
"You'd think that in the rock 'n' roll world, I guess people think of it as a liberal sort of thing and it wouldn't be a problem, but guys in bands had problems with it. We wouldn't get sound checks because people were threatened."
