Prepare to be even more disappointed about The Flash's poor box office debut!
Shortly after it was announced that James Gunn and Peter Safran were taking over as co-heads of the newly established DC Studios, we heard that Christina Hodson (The Flash, Birds of Prey) had been working on a treatment for a live-action Batman Beyond movie.
The project was said to have been shelved when the decision was made to reboot (or semi-reboot) the franchise with the DCU, but it seems there may have still been plans to get the film into production... before The Flash crashed and burned!
During the last episode of the Fatman on Batman podcast, Kevin Smith revealed that he'd heard from the son of Michael Uslan, Executive Producer on the Batman movies since Tim Burton's 1989 original, that Warner Bros./DC Studios were planning to move forward with a Batman Beyond film starring Michael Keaton if The Flash proved to be successful enough at the box office.
Of course, short of a dramatic turnaround, The Flash does not look set for a successful run in theaters, so we can probably forget about a Batman Beyond live-action adaptation anytime soon. However, we did recently hear about a Daniel Casey-penned script for an animated take that was supposedly being developed as Warner Bros.' answer to Sony's Spider-Man: Into The Spider-Verse franchise.
That project also stalled after the SCU slate announcement, but could still see the light of day.
