If it’s possible to create a riot in cyberspace, “Twilight” star Kristen Stewart may have done just that a few weeks ago, mentioning a scene in the upcoming movie in which “[Robert Pattinson as Edward] throws me over his back, right before he’s going to tell me that he’s a vampire, and then he runs over the treetops.”

Some 1,600 comments later, the debate rages on, over whether the scene strays too far from the book’s depiction. Naturally, when we landed the first-ever on-set “Twilight” interview with Stewart’s co-star Rachelle Lefevre, we had to get her thoughts on whether those treetops would be tweaking “Twilight” too much.

“There’s a scene where Edward reveals to Bella that he is a vampire, and he doesn’t just reveal that he’s a vampire, he reveals all that that encompasses,” Lefevre said of the script. “It’s almost a demonstration, and I think that scene is going to be amazing.”

The actress, who plays the vampire Victoria in the flick, added that the cast has spent the past few weeks training for such stunts. “I haven’t seen all of the stunts specifically, but I did see a setup of that while I was doing my wire work,” she revealed. “I would imagine that [Stewart's statement] is exactly what they are going to do.

“They’re talking like it’s really going to happen,” Lefevre added. “We did a rehearsal at one point where [director] Catherine [Hardwicke] was like, ‘They went up in the tree, but we’re not doing that today.’ I think we are really doing that.”

Before you post your comments below, Lefevre wants you to consider that the treetop-running thing does happen at other times in the “Twilight” series, even if not in the moment when Edward reveals himself.

“I think that there is a scene where a character ends up in a treetop in the book,” she explained. “I don’t want to say who, but there are treetop scenes in the book. But there are also things that are described in the book — the stunts that we are going to be doing, as far as I understand it, are very accurate to what’s in the book.

“You want to put as much action and excitement into the movie as possible,” Lefevre said of the controversy. “So sometimes things get heightened.”

So, twi-hards: What do you think?
