More seriously, Pattinson said the audition consisted of several of the film's key scenes, including when Edward tells Bella that he is a vampire and they try to kiss. Afterward, Pattinson lobbied the film's director, Catherine Hardwicke, for the role -- the first time he had ever done so. "It's the biggest job I've ever got," he said. "So yeah, it worked."
Getting the vampire's look just right, however, took some time. "I had really long hair extensions down to my waist and literally clown makeup," Pattinson said. "I looked like a very scary drug addict. The producers freaked out."
After getting rid of the extensions, letting Pattinson's naturally pale skin shine through and adding contact lenses, Edward was ready for the big screen.
Both stars described tension on the set, which they said they used to fuel the tension between their characters. Bella, a 17-year-old high school student, is human. When she falls in love with her classmate Edward, the characters realize they can never consummate their relationship.
"It's such a strain. It's always hard, never easy. It's always very difficult for them," Stewart said about their characters. "The fact that I was feeling that was probably right."
"Also we're like the most annoying people to work with," Pattinson said, looking over at his co-star, who didn't say anything.
"I feel like I'm digging a hole for myself," he said, trying to break some of the tension that appeared to surface between the actors.
"We're kind of annoying to work with in the sense that this is how we behave," Stewart agreed. "We were driving each other crazy. Hopefully, it comes across in the movie and it works."
And if it works, Stewart and Pattinson said they would be back for more. After all, there are three more books in the series.
"I typically only get to be with a character for six weeks," Stewart said. "I've never been with one person for so long. I feel pretty responsible for her. Sure, I would like to do more."
Added Pattinson: "I just don't want to have the same hairdo."
The movie "Twilight" opens nationwide today.
