Why isn't there a forum for discussing films?

Here in the Verge forums, we have a forum for gaming, as well as a forum for discussing books. Why isn't there a forum for discussing films, or music? I saw Under the Skin today and wanted to have a discussion on it but I didn't know where to go. Betamaxed? The Verge posts reviews of films (Including the aforementioned Under the Skin), and yet I can't discuss it anywhere besides the comments of the review. And there aren't any book reviews, but I can discuss books? Hardly seems fair. What would it take to add a film forum?
