A few weeks ago we heard Mark Hamill would reprise his infamous voice-acting role as the Joker for Batman: The Killing Joke, an animated adaptation of Alan Moore's 1988 graphic novel, universally hailed as one of the best in the Dark Knight's history.

And guess what? The movie's gonna be rated R.

DC is releasing an R-rated cut of Batman v Superman: Dawn of Justice for home video, but The Killing Joke is the comic empire's first R-and-only-R film. Here's what Warner Bros. Animation & Warner Digital Series president Sam Register told Entertainment Weekly:

“From the start of production, we encouraged producer Bruce Timm and our team at Warner Bros. Animation to remain faithful to the original story—regardless of the eventual MPAA rating. The Killing Joke is revered by the fans, particularly for its blunt, often-shocking adult themes and situations. We felt it was our responsibility to present our core audience—the comics-loving community—with an animated film that authentically represented the tale they know all too well.”

TL;DR: This thing wouldn't have really been The Killing Joke if it was entirely suitable for young audiences. After the big L that was Batman v Superman: Dawn of Justice, Caped Crusader fans are scoring a much-needed win here.

The movie will premiere at San Diego Comic Con and hit home video later this year. Kevin Conroy is returning as the voice of Batman.
