Anna Kendrick is glad that she can be part of the Twilight Saga without any of the "bulls**t" associated with it.

The American actress portrays Jessica Stanley in the vampire film series the classmate of Bella Swan, played by Kristen Stewart.

Anna acknowledges that being part of Twilight has won her a dedicated fan base. However, she is glad her small part in the film franchise doesn't attract too much negative attention.

"Twilight was this huge thing that spiralled out of control," she said.

"When something gets that big, there's always a backlash. But I don't have people following me around everywhere, or writing horrendous things about me on the internet. I appreciate the fact that I get to reap all the benefits of this crazy mega-franchise with almost none of the bulls**t that a lot of the cast has to deal with."

Anna garnered critical acclaim for her role as an ambitious businesswoman in Up in the Air, alongside George Clooney. She also plays inexperienced psychologist, Katherine Katie' McCay in comedy drama 50/50.

The 26-year-old gets annoyed when people criticise her choice of film roles.

"Somebody asked me recently why I play young professionals," she said in an interview with British newspaper The Independent.

"I thought: 'What am I supposed to be playing... a senior citizen?' But I don't define characters by their profession or age. It's just about what I feel that I can do with them."

Anna is keen to diversify her film roles. However, she is unsure about having to portray a villain.

"Oh my god. I'm one of those people who hadn't seen Mad Men until a couple months ago and I genuinely don't know how Vincent Kartheiser can play that character slimy adman Pete Campbell with no redeeming qualities," she explained.

"I actually had to ask myself: 'Could I be someone so horrible without trying to sneak in little moments where I apologise to the audience?' I really don't think I could."
