Fangs For The Memories

As for the film itself, there's more music in it than "Twilight"; it features roughly 20 cues, Weitz says. "The movie has a lot of spots for music and a lot of spots for score, and we're trying to ride a very delicate balance and not make it wall-to-wall carpeting," he says. "I think there is a threat to modern film in that there's not enough silence. And so it's very rare you actually get to hear the entire song played out." The one song that does play in full during the film, he says, is Yorke's "Hearing Damage," which underscores a fight scene.

Weitz is well-known for pushing music in his movies; he was a producer on last year's "Nick & Norah's Infinite Playlist" and he was nominated for an Oscar for best adapted screenplay for the 2002 music-intensive film "About a Boy." "He's got good musical taste and he's very into it," Katz says. "He wasn't just like he was the director out there, he was part of the team."

So to address the question fluttering in a million teenage girl hearts: Why does Pattinson not make an appearance on the second soundtrack?

The answer: He didn't want to. (Sorry, girls.) "We asked if Rob wanted to do it, but his music is kind of his private stuff in a way-as opposed to this huge public dazzle on him on the moment," Katz says. "We wanted to respect that. If he comes to us on the third one and he wants to do something, then we would obviously be delighted."

Right now Pattinson is filming "Eclipse" -- the third book in the "Twilight" series -- in Canada in preparation for a release in summer 2010. Katz and Patsavas are back onboard for the soundtrack album, and while a deal with a record label isn't finalized yet, Katz says, "We would like to work with Atlantic again."

The plot of "Eclipse" provides more rich sonic territory, including a vampire versus werewolf battle and lots of chaste "ragged breathing" between Bella and her supernatural boy toys. In other words, it adheres to the same formula that has sold 70 million copies of Meyer's books worldwide, according to the publisher, Hachette Book Group-an alchemy of hormones and horror that spawned films and soundtracks to feed off the stories' success.

"There's no illusion that it wasn't the 'Twilight' phenomenon that helped make it so successful," Katz says. "While the music is great, if it came out by itself, it wouldn't have the same impact at all."
