Robert Pattinson, the actor who shot to fame playing Edward Cullen in the iconic vampire movie, Twilight, has claimed that he doesn't know how to act.

"I only know how to play scenes, like, three ways," Pattinson told The Observer. "I'm nervous on, like, every single movie."

Pattinson, who was recently tapped to play Batman, has also starred in several Harry Potter movies.

"If I'm doing a scene and I see that the other actor is expecting me to do it the way I'm doing it, if I can just see that it hasn't surprised them, I immediately feel stupid," he shared.

"Because I don't really know how to act, I kind of wanted to somehow make it real, and one of the ways I've always thought makes that a little bit easier is if you shake up your physical state just before action," he told the publication. "You end up walking into a scene having a different feeling."
