That’s right Twilighters, you will now be able to catch the first adventure of Bella (Kristen Stewart) and Edward (Robert Pattinson) Nov. 21, 2008. The big-screen adaptation of Stephenie Meyer’s first novel of the saga was originally scheduled to open Dec. 12, 2008.

In the film, a teenage girl risks everything when she falls for a vampire. Catherine Hardwicke directs a screenplay by Melissa Rosenberg. Taylor Lautner, Billy Burke and Nikki Reed co-star.
