Kristen Stewart (The Messengers) will star in Summit Entertainment’s Twilight, a vampire thriller-romance based on Stephenie Meyer’s best-seller. Catherine Hardwicke is directing from a script by Melissa Rosenberg. Stewart will play Bella Swan, a 17-year-old who becomes drawn to classmate Edward, who is a vampire. Their unorthodox romance puts her in physical danger when Edward’s nemesis comes to town and sets his sights on Bella. “Twilight” and its sequels have topped best-seller lists at the New York Times and USA Today and has garnered legions of devoted teen?age fans. Summit is looking at the movie as a potential franchise with a Romeo and Juliet-like hook. Production begins in February.
