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."
