Of course DC’s film adaptation of The Killing Joke will be rated R
Looks like you don’t have to worry about DC turning Batman: The Killing Joke into a story about how The Joker once took Barbara Gordon out for ice cream and they had a fine time and shook hands after he walked her home. Entertainment Weekly reports the latest entry in the DC Universe Original Movie franchise is receiving an R rating, the first film in that series to do so. (Though technically the second Batman film to receive the rating, if you count the upcoming home-video release of Batman V. Superman: We Swear This Version Sucks Less.)
