Though he has done intimate scenes, but Hollywood heartthrob Robert Pattinson is not ready to shed all his clothes on screen now and the actor has reportedly refused to do a naked role in his latest project Cosmopolis. The Twilight star had promised director David Cronenberg to do everything else for the film except baring all. As the actor is a big admirer of Cronenberg, he even tried to shoot the scene but five minutes before the filming, he found himself very uncomfortable and expressed his inability to do the racy scene. "He took it really well. At the start, it's a very bizarre scene that you won't see again in another movie, I promise," Pattinson said. Apart from this scene, the young actor enjoyed a lot during the making of the movie. Initially, the star was not confident enough to play the role in the film which is based on Don DeLillos novel of the same name. "I spent two weeks in a hotel room worrying and confusing myself," he said.
