Rumor casters for the movie.

[DJ VASC]

Deborah Aquila & Tricia Wood the same casters who made the cast for Twilight.
Kristen Stewart as Max, maybe?
Robert Pattinson as Fang no, as Dylan sure.  

[My Doll Heart]

It's being made by the same people who made Twilight. They were almost gonna have the same actors too but they still have a contract with Twilight.
