Warner Bros. will distribute movies through Facebook, the studio revealed this week. The first movie to hit the social networking site will be The Dark Knight.

The move is experimental. It comes on the heels of another unorthodox movie-distribution move, in which the studio offered two movies as Apple Store apps for the iPad, iPhone, and iPod touch.

To rent The Dark Knight on Facebook, users would go to its official Facebook page. The cost would be $3 or 30 Facebook credits. The credits could also be used to rent games and other apps. You'd have 48 hours to watch the movie, comment, and interact with friends.

Movie rentals will be limited to U.S. Facebook users, at least for the time being. Warner will release additional titles on Facebook over the next few months.
