Robert Pattinson: What Happens in My Pants Stays in My Pants

In an interview for Metro France that quickly got picked up around the festival, the Twilight star, 26, was quoted as saying, "Five minutes before we filmed, David told me, 'I want to see the bottom of your balls on the top of the frame.' At the moment, I reminded myself that I would do anything for him. So I went back to see him and told him that wouldn't happen."
And how did the filmmaker of The Fly, Scanner, Eastern Promises and A Dangerous Method react to his leading man's decision?
"He took it really well," Pattinson is quoted as saying. "At the start, it's a very bizarre scene that you won't see again in another movie, I promise."
As it was, the actor admitted at the press conference after the Cannes screening that he was already anxious about making the sexy and (at-times) violent movie – to the point that he wasn't sure he could pull off the role.
"I spent two weeks in a hotel room worrying and confusing myself," Pattinson said.
The London-born-and bred heartthrob also said he disagreed with some critics who found the movie, based on the novel by Don DeLillo and set for the most part in a limo while Pattinson's character tries to go get a haircut, to be about the end of the world.
"I think it's a very hopeful movie," he countered. "Maybe I'm just a depressive, but I think the world needs to be washed and cleaned every once in a while."
Meanwhile, Pattinson and his real-life girlfriend, Kristen Stewart, who both have films in festival competition, arrived in Cannes this week and have been seen sneaking kisses on the Croisette.
Wednesday night, Pattinson attended the red-carpet premiere of Stewart's film, On the Road, while she is as expected to accompany him at Friday night's official screening of Cosmopolis.
