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.”
