The upcoming animated adaptation of Batman: The Killing Joke will have new story elements added, according to executive producer Bruce Timm.
"The one big difference about it, as opposed to those other projects, is The Killing Joke... the source material is really not long enough to make an entire feature film out of," Timm said to ConTV. "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."
Timm then announced that the film will make its world premiere at Comic-Con International: San Diego this July. No home video release dates were given.
