Trying to get some details for Twi-hards, Access Hollywood asked Peter if Breaking Dawn has any "vampire sex" in it?

“Well, yeah, for sure,” Peter said. “Not for Carlisle, he’s 350!”

“Viagra can’t even help him at that point!” Access' Billy Bush joked.

“Vampire Viagra,” Peter added with a laugh.

Okay, so there won't be "vampire Viagra" in the film, but there's plenty of other good stuff!

“We have baby vampires, lots of fun stuff going on in that movie,” Peter said. “Eclipse was my favorite book, but I think Breaking Dawn is my favorite script. I really like what they did with them. There’s a lot of fun surprises for the audience.”
