Twihards have long been anticipating seeing Bella (Kristen Stewart) and Edward (Robert Pattinson) honeymoon on Isle Esme and consummate their marriage amid flying feathers. And as audiences will see when The Twilight Saga: Breaking Dawn - Part 1 arrives in theaters this Friday, the love scene does not disappoint. But, according to the stars of the movie, things could have been even more steamy - if it weren't for director Bill Condon needing to keep the action PG-13. "There's a version where it was really intense," recalls Pattinson in this week's EW. "Cinematically, cut all together, it's awesome," says Kristen Stewart. "But we didn't really do that scene."

"And when we did," adds Pattinson, "they kept telling us to stop."

The PG-13 rating also limited things with regard to the climactic birth scene, which takes place at the end of the film. "That's what I'm really disappointed about - and I've talked about it with Bill," says Stewart. "It was more sympathetic or something when I played the scene with less energy, and it made it easier for him to tell the story. But in the book, Bella is screaming, 'NOOOOO!' [Stewart stands and demonstrates.] And I did it like that - crazy and Exorcist-like. I was going for this weird mix of turning into the most feral mother you can imagine and also fighting for my own life. I mean, I was a nutcase. I was an absolute nutcase."

"I do still love the birth scene," says Lautner. "I know it's frustrating that some things aren't in there."

"Yeah," says Stewart, "I still love it too."
