New Moon has been big news for Kristen Stewart and Dakota Fanning, shattering box office records and expectations, even for the highly anticipated franchise. Eyes are turning next to their follow-up film, which happens to reunite them. "The Runaways" casts Stewart as rocker Joan Jett.

"I can only play characters that I feel like are real people and in a complete way and in such a whole way," Stewart said. "If I fake any aspect of it I will have failed them and literally they're slaughtered. It's like these characters, they don't exist anymore unless I do it. So in terms of approaching parts, thank God I don't have to do that. It just happens. Playing Joan Jett had nothing to do with Bella. It was a small period of time that I had to do it but it was an opportunity that I jumped on."

Fanning plays Cherie Currie, the lead vocalist for Jett's first band. "It was really great making "The Runaways" with her after "New Moon,"" Fanning said. "We became really good friends and really close throughout all the experiences we've had this year. I couldn't ask for a better person to do three movies in a row with than her. It was really good to know each other so we weren't complete strangers when doing The Runaways."

The real Jett was involved with the film also, working closely with Stewart. "I got to know Joan not only as her now. I feel like through footage and just through the script and the story, everything, I feel like I got to know who she was in such a whole way that it's not about imitating even though I was really concerned about details being right, like gestures and stuff. I really wanted to do a good impersonation but I also didn't want it to be imitation. I wanted it to be natural."

"The Runaways" is out next year.
