Kristen Stewart might get to kiss Robert Pattinson but it is working with top actors that gets her excited

She was thrilled to be hand picked by Sean Penn to be in the movie Into the Wild.

Kristen told Joy magazine: "I think it's one of my favorite movies, and not just because I'm in it. I was so lucky to get that role.

"Sean Penn actually called me on my cellphone. He's very bold and secretive. Plus, I know he's sure of the effect that one phone call of him can do to a person. He told me who he was and said: "Hey, I'm working on this movie that I love. I care about it more than anything and I'm reaching a point in which I don't know what to do".

"He asked me to read the script for him with the other actors. I read for the sister's part, who narrates the whole story. Two days later he called me and said "I don't know how you'll fit into all of this, but I really want you to do this movie with me, and I'll find you your perfect role". And there were two roles, the role for the main character's sister, and Tracy the singer. And he chose Tracy for me.

"That moment was amazing. That's the reason why I chose acting, to get to work with people like Sean Penn."

Kristen also revealed what it is about Bella Swan that excites her.

She said: "She's a very strong girl. If you look a it superficially she's a character full of clich: she's the damsel in distress. But what's amazing about her is that it's her strength that moves the story. Edward does it too, but Bella is brave in a very scary situation. She's very confident too."

Enligt rykten så var det faktiskt Emile Hirsch som tipsade Catherine om Kristen efter han hade gjort into the wild.
