Suicide Squad director David Ayer praises James Gunn’s upcoming Superman: Legacy as part of the DC Universe reboot. While 2023 marks the end of the DCEU timeline, Gunn and Peter Safran’s new DC Universe will serve as a fresh start for Warner Bros. Discovery in running an interconnected superhero franchise. DCU Chapter 1, “Gods and Monsters” has multiple movies and TV shows in the works, but Superman: Legacy is the biggest project thus far, as Gunn’s film will help set the foundation for the new continuity.
