In a decision that will either intrigue or enrage fans of Alan Moore’s classic Batman comic The Killing Joke, it has been announced that DC will be adding some new story elements to their R-rated animation adaptation.
The decision has been made as a way to fill out the film’s runtime – which fans of the book can’t really say they’re surprised at – and was revealed on the special features on the Justice League vs Teen Titans Blu-ray.
The main addition will revolve around Barbara Gordon as Batgirl, before her run in with The Joker.
Speaking about the project’s run time back in January, executive producer Bruce Timm told ComicBook.com “The one big difference about it, as opposed to those other projects (The Dark Knight Returns Part 1 and 2), is The Killing Joke… the source material is really not long enough to make an entire feature film out of, 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.”
This Batgirl “prologue” will be approximately 15 minutes long, which is expected to knock The Killing Joke’s length up to the 65-75 minute mark, the standard for DC Universe animated films.
The Killing Joke will premiere at San Diego Comic-Con and will get a home release this summer.
