Kristen Stewart terrified of 1984 adaptation

Kristen Stewart is "terrified" of starring in the upcoming romantic adaptation of George Orwell's 1984 as critics are expecting a classic movie.

The Twilight star has signed on to star opposite Warm Bodies actor Nicholas Hoult in futuristic love story Equals, which is a take on the 1956 film based on Orwell's classic novel.

Despite her experience in the popular vampire film franchise, Stewart tells the Associated Press she is wary of the role as movie fans are already predicting the film will be a hit.

She says, "I can't believe I agreed to do it. I'm terrified of it. Though it's a movie with a really basic concept, it's overtly ambitious. It's a love story of epic, epic, epic proportion. I'm scared."

Stewart even confided to director Drake Doremus that she fears she is not up to the task of taking on such a high-profile role, but the Like Crazy filmmaker refused to believe her excuses.

The actress adds, "I trust Drake's process and I know we will do something really natural and real. But I told Drake, 'Don't expect that I am going to be able to do this. It's too hard.' But he wouldn't take 'no' for an answer. I've given directors disclaimers before, but never this much."
