Joan Jett who will be played by Kristen Stewart in the new movie 'The Runaways'has stated one of her aims is to find her Irish roots.

" My father was Irish, and I believe he came from County Mayo. Want to explore that a little bit more when I have the time...

She also told movies.ie that Kristen Stewart of 'Twilight ' fame did a great job in the new movie playing her.

"I never wanted a movie in the first place. I figured, all they could do was screw it up. So, I wasn't really into it...

I decided, once I was going to sell them my life rights and stuff, that I wanted to be involved in all of it, and be there as much as possible.

And once I met Kristen Stewart, and talked to her about the role, and about her take on it, I was really pretty confident that she was going to have what it takes to get where she needed to get.

So, I think a lot of it comes down to the actors, that they took it so seriously.

They did a lot of their own research, and then Cherie Currie got to work with Dakota Fanning, which I'm sure was helpful for Dakota.

And I was there on set every day, watching Kristen, to be there for her, if she needed to ask me any questions. 'How would you do this?'

I also wanted to watch the movie production. I wanted to make sure that nothing got too far - what's the word - afield? So, this is a movie, so there are a few embellishments, but it's based on a lot of factual things, and I just wanted to stay around and make sure that it was in the realm of reality."
