"Not surprisingly, reports hinted at an on-set romance between Pattinson, 22, and Stewart, then 17, during the shoot in the Oregon wilds. Their off-screen chemistry was enough to concern Hardwicke, who revealed she was worried the duo's obvious closeness would mean the end of Stewart's relationship with her boyfriend of five years, actor Mike Angarano.Angarano is a close friend of Hardwicke's since she directed him in 2005's Lords of Dogtown.
Stewart takes a breath and looks at the floor when told of Hardwicke's comment.
"We were fine. I have not left my boyfriend for Robert Pattinson," she says quietly.
"But we went through a lot together. It is crazy to go through something that heavy in real life. At the end of it you are inevitably going to have something.
"I know a version of him better than anybody else in the world because I did this movie with him."
And they will do more. Both have signed contracts to appear in at least two Twilight sequels.
While stardom does not excite Stewart, the idea of being in a film franchise does".
Kristen Stewart mentions how was to work with Sean Penn and Emile Hirsch in this interview:
-What impact did working with Sean Penn on Into the Wild have on you?
-It definitely opened my eyes to a different creative process. His direction is very specific, but still, he lets things happen. He just wants you to go for it. Once he picks his characters, he gives you that confidence. Plus, I really enjoyed working with Emile [Hirsch]. He’s such a good friend of mine. That was like a little section of my life. It was very fruitful.
