Try to imagine Twilight without Robert Pattinson.
Playing the vampire Edward Cullen made Pattinson a household name, but as he recalled in an interview with The New York Times over the weekend, he was nearly fired while making the first film, released in 2008. His agents intervened, flying to the Canadian set to calm him down. "I didn't have to kiss anybody's [butt] the entire time," he recalled. "I don't think I did, anyway."
(The movie star told Yahoo! Movies in 2012 that he took his method acting to so seriously that he "was fighting with everybody in control all the time...to the point where I almost got fired.")
