In some very reassuring news, Reuters is reporting that Summit Entertainment has acquired the rights to the rest of the saga!
It has hired "Twilight" scribe Melissa Rosenberg, a writer/producer on Showtime's "Dexter," to adapt the first two. "Breaking Dawn," has not attached a writer.
While this does NOT confirm that the rest of the books will be turned into movies, this is certainly very good news for the franchise. We'll keep you updated!
UPDATE: Robert Pattinson has a few comments about New Moon that he made to the Chicago Tribune:
A sequel [aka New Moon] may get the green light this month, he said.
"They will literally decide the next day or the day after" once the movie opens, Pattinson said. "I think they only have plans to do the second one. There's no script for the third one. The script is already done for the second one."
