Robert Pattinson: Playing Cedric Diggory in 'Harry Potter' was 'so terrifying'

Before Robert Pattinson was Edward Cullen, and certainly before he was Batman, he was Cedric Diggory in "Harry Potter and the Goblet of Fire."

"He's the first death in Harry Potter, which is my claim to fame," the 35-year-old actor told GQ, adding, "I'd sort of fallen into it. I mean, it was so terrifying. I remember the first scene I ever shot on that was in the magical maze at the end, and I'd never done anything with special effects and stunts. It was a big deal, at the time."

"It felt very, very intimidating," Pattinson continued. "I think I'd read a book on method acting. The only thing I really got out of that was just beating yourself up before every single scene. That was basically my only concept of how to prepare myself for a scene. I was psyching myself up as if I was going into a fight or something before these scenes. And just screaming into a pillow and punching myself."

In the 2005 movie — the fourth installment in the Harry Potter film franchise — Cedric is chosen to battle in the famed Triwizard Tournament. After agreeing to share in victory with Harry (Daniel Radcliffe), in a cruel and sick turn of events, Cedric is killed by Voldemort.
