The rumor of Justin Bieber being cast as Robin are just that at the moment, a rumor. Some that are wild as hell and making a lot of people angry and frustrated. Justin did however last night post on Instagram this picture of him holding a first draft of the movie script with the hashtag #robin. If they decide to take this route with the film, Ben Affleck as Batman actually seems like a good idea right about now.
Please movie gods do not let this happen.
