Last summer, it was announced that Alan Moore and Brian Bolland’s classic graphic novel, Batman: The Killing Joke will be adapted as a feature film by director Sam Liu and animation legend Bruce Timm. The original story was released in 1988 and it is widely regarded as one of the definitive Joker tales.

During a new interview with ConTV, Timm revealed that The Killing Joke adaptation will expand on the 48 page story by Moore and Bolland with new material to ensure that the film is feature-length.

“The one big difference about it, as opposed to those other projects (The Dark Knight Returns Part 1 & Part 2), is The Killing Joke… the source material is really not long enough to make an entire feature film out of,” said Timm. “So we actually had to add a lot more story to it. Which is tricky. But I think we came up with a really good solution on how that worked.”

The producers of The Killing Joke film have previously noted that they have the greenlight to make this the first-ever R-rated Batman story, but it’s unknown if they will actually go through with it.

Although Mark Hamill is reportedly reprising his role as the Joker for Batman: The Killing Joke, Warner Bros. Animation has yet to officially announce the cast. However, Timm confirmed that Batman: The Killing Joker will get a world premiere at San Diego Comic-Con 2016.
