'Twilight's' Ashley Greene is like 'Butter'

ashley-greene-new-moon-prem.jpg"Twilight" vampire Ashley Greene is about to sink her teeth into "Butter."

Greene has signed on to star with Jennifer Garner in a comedy about competitors in a butter-carving contest in a small town, The Hollywood Reporter says. Garner is also producing the movie.

Despite the subject matter, it's not a Christopher Guest movie. Newcomer Jason Micallef wrote it, and Jim Field Smith ("She's Out of My League") is going to direct.

Greene will play a character named Kaitlen Pickler, whom the HR describes as a "rebellious high school teenager." She's scheduled to begin filming the movie next week, fitting it in before the press onslaught for "Twilight: Eclipse's" June 30 release kicks into high gear.
