Robert Pattinson has said he regrets his behaviour while filming two Harry Potter films, a new biography claims. Pattinson played Cedric Diggory in Harry Potter And The Goblet Of Fire and Harry Potter And The Order Of The Phoenix but says he didn't make enough of the chance given to him. "I was a real prat for the first month," he is quoted as saying in Robert Pattinson: The Unauthorised Biography. "I didn't talk to anyone. I just drank coffee and told everyone I was 24 and this famous theatrical actor just back from South Africa. I kind of blew it after the Potter films. There was a chance for me to really kick on and use the exposure, but I didn't really want to do anything."More celebrity gossip on handbag.com.
