The first film in the DC Universe Original Movie series to receive an R rating will be Batman: The Killing Joke.

Entertainment Weekly says this has been confirmed by Warner Bros'. home entertainment division. In addition, this will be just the second Batman film to receive the Restricted rating after the extended home release of Batman v Superman: Dawn of Justice.

Batman: The Killing Joke is an animated movie and will be coming straight to DVD and Blu-Ray. It will be debuting at this year's San Diego Comic-Con, and will be coming to homes later in the year, although no set release has been scheduled yet.

Kevin Conroy and Mark Hamill are set for the roles of Batman and the Joker, and the movie will be adding to the story of the original comic.
