Warner Bros is testing a service that will offer select movies for purchase or rental through the public pages of these movies on Facebook.

The service is only open to people in the United States, according to Miami Herald.

Facebook users who visited the official page of "Batman: The Dark Knight" could click a "watch" icon and pay 30 Facebook credits, or $3, to watch the movie. The movie is streamed through a Facebook application.

Warner Bros. didn't say how much it will cost to buy movies.

"Making our films available through Facebook is a natural extension of our digital distribution efforts," said Thomas Gewecke, president of Warner Bros. Digital Distribution.

Renters have access to a movie for 48 hours and can replay it as many times as they like.
