"Twilight" regular Ashley Greene has joined the comedy "Butter," a project produced by and starring Jennifer Garner.

The Weinstein Co. film, which begins shooting in Louisiana next week, follows a number of competitive characters in a small Midwestern town as they become entwined in an annual butter-carving contest. Greene will play a high school rebel. Jim Field Smith ("She's Out of My League") will direct.

Greene just wrapped shooting the thriller "The Apparition." She returns to theaters in June with "The Twilight Saga: Eclipse," reprising her role as Alice Cullen.
