Kristen Stewart: Twilight Is Part Of Who I Am

Kristen Stewart might have moved on to more grown-up roles since she played Bella Swan for the last time in The Twilight Saga: Breaking Dawn - Part 2, but she's in no hurry to forget her roots.

Speaking to E! News, the 24-year-old star explained that the hugely popular franchise is part of her identity now.

"On an exceptionally obvious note, it's opened a lot of doors, but I've become who I am because of that," she said. "It was five years of my life.

"I was able to work for years and years on something that took so much out of all of us and did not leave us empty, replaced every bit that it took.

"That's why I love to do my job, it was just a very elongated version of that. It was something that was really personal for a couple of years. It's a part of whom I am."

Now promoting her new movie Camp X-Ray, she said she hopes the film sheds a glimmer of light on a dark topic - namely the detainment of terrorist suspects by the US.

"My initial motive to want to be a part of this is just that there was a really simple, intimate, interior story going on in a place that asks bigger questions.

"So I think the movie, while remaining entirely objective, is a reminder - it doesn't answer any questions but it asks them."
