Warner Bros. Animation hosted a panel at San Diego Comic-Con ahead of the premiere of Batman: The Killing Joke, the much-anticipated adaptation of the beloved story that many consider the seminal Batman and Joker tale. To close out the panel before showing the film, they announced the next three films that will release from their DC Animated Originals line.

Coming first is the already-announced Justice League Dark, which brings the team of supernatural heroes together to combat a magical threat. WB confirmed both John Constantine and Swamp Thing as characters in the film.

Next up is Teen Titans: The Judas Contract, an adaptation of a story arc that WB Animation has had in the works for years, but of late has been denying that it's actually being actively developed. The movie adapts one of Marv Wolfman and George Perez's most acclaimed stories from their seminal run.

Finally, next summer's film was announced, and it's Batman and Harley Quinn, a new completely original story from Bruce Timm, who co-created the latter character with Paul Dini. No details were announced about the film other than that, though.
