Robert Pattinson: 'I'm not buff enough for action movies'

Robert Pattinson fears he'll never land a role in a major action film as he's so puny.

The Twilight Saga star is adamant he's crippled by shyness and lacks the confidence and bulging muscles to convincingly pull off the image of a movie tough-guy.

He tells Empire magazine, "I'm taking baby steps and hoping people keep employing me. That's my biggest problem, confidence... I'm not buff enough for robot movies."
