(AP Photo/Warner Bros. Pictures, Stephen Vaughan, file) (Newser) – Look out Netflix? Warner Bros. has decided to test out a movie rental service on Facebook, according to the Hollywood Reporter. Anyone who "likes" The Dark Knight will be able to spend 30 Facebook credits, meaning $3, to stream the movie to their computer, where it'll be viewable for 48 hours. You'll also have "full Facebook functionality" while watching the movie, so you can comment on the action, or, knowing you, ignore the movie as you get sucked into your friends' status updates. For now, the deal only applies to Dark Knight, but the studio promises to roll out more titles in the coming month.
