Kristen Stewart, who stars alongside Jennifer Lawrence's boyfriend Nicholas Hoult in "Equals," a futuristic love story directed by Drake Doremus, recently said in an interview that she was nervous about accepting the role.

"I can't believe I agreed to do it," Stewart told the Associated Press on Monday. "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," she added. "I'm scared."

The movie, which will commence filming later this year, is an adaptation of "1984," a film based on George Orwell's novel of the same name about a futuristic society.

According to reports, Stewart's role was initially offered to Lawrence, who had worked with Doremus in 2011's "Like Crazy." But despite reading the script and liking it, the "Hunger Games" actress declined the role as she couldn't see herself playing the part.

"Jen and I worked together before and she was fantastic," the director said. "It's exciting to talk about the character with different people, but it became evident in my head that Nick and Kristen would have great chemistry."

Interestingly, this is not the first time Lawrence and Stewart have been considered for the same role. Lawrence, 23, auditioned for the role of Bella Swan in "Twilight" when she was 17 years old, but eventually lost out to Stewart.

During a 2012 interview with The Guardian, Lawrence said she is glad she lost out to Stewart.

 "I remember when the first movie came out, seeing Kristen Stewart on the red carpet and getting papped wherever she went. I'd had no idea Twilight would be such a big deal. For me, and assuming for her, it was just another audition. Then it turned into this whole other thing."
