"You know, I develop more movies than I make," Liman, whose films include The Bourne Identity and Edge of Tomorrow, told CinemaBlend. "There's a weed-out process, and it's just that when you get to the comic book one, suddenly everybody hears about them. So, the script never got to a place that was special enough for me. Not for lack of trying.
Without a script he was comfortable with, Liman decided to move on to Lionsgate's Chaos Walking, based on author Patrick Ness' series of young-adult sci-fi novels.
Justice League Dark isn't the first comic book adaptation Liman has left: He was previously attached to Fox's Gambit, but exited because of dissatisfaction with the script.
Based on the concept introduced in 2011 as part of DC Comics' New 52 relaunch, Justice League Dark followed a group of supernatural heroes who fought magical and demonic threats the traditional Justice League couldn't handle. The roster included John Constantine, Swamp Thing, Deadman and Zatanna. While the team has never been adapted for live-action, a Justice League Dark direct-to-video animated film was released earlier this year.
Despite the lack of a director, Warner Bros. listed Justice League Dark as part of the DC Extended Universe during its presentation last month at Comic-Con International in San Diego.
