Batman: The Killing Joke has had plenty of mentions by Mark Hamill (The Joker) that the first R-rated animated film from DC Entertainment would be very mature in nature. Not only is the subject matter from the original Alan Moore story not for PG-13 audiences, as we have been shown our first glimpse of the reasons why its R-rated.

As seen, both Batman and Batgirl are apparently love interests in this film. It wouldn’t be the first time that the two were hinted to have sparks, as in Batman: The Return of the Joker teased the relationship, as well as the short-lived Birds of Prey television series hinted at it as well.
It’s also not the first DC animated film to feature a sex scene, as Batman: Assault on Arkham featured a similar scene between Harley Quinn and Deadshot, which makes one wonder how that got past the MPAA for a PG-13 rating.
