Jackson Rathbone Relives 'Breaking Dawn' Screening

'As soon as Taylor ripped off his shirt, we all tried to yell as much as possible,' he laughs to MTV News.

In addition to the whole fame-and-fortune package that comes with being a member of the "Twilight" cast, one of the additional benefits is that you get to see the finished film before anyone else.

When MTV News caught up with "Twilight Saga: Breaking Dawn - Part 1" star Jackson Rathbone recently, we asked him to talk about his first-time viewing experience.

"I got a nice little private screening," Rathbone said. "There were about six [castmembers] in the theater. I was saying, 'This is what it would be like watching "Twilight" if no one liked it,' " he joked. "If it had failed, that's exactly what it would have been like: six people in the theater."

In all seriousness, however, Rathbone said he and his co-stars had a lot of fun watching the film together and interacting with the screen.

"As soon as Taylor [Lautner] ripped off his shirt, we all tried to yell as much as possible to supplement the lack of little teenage girls [screaming]," he said. "It was fun. We had a good time with it. Nikki [Reed] and I were making fun of each other the whole movie. Any time one of us would come onscreen, we'd poke each other," he said with a laugh.

In addition to those swoon-worthy shirtless moments, Lautner has promised us that we'll be shedding some tears.

"You are going to face a lot of emotions, definitely," he teased. "You are going to be angry. I guarantee you [that] you will cry multiple times."
