Michael Keaton returns in the latest trailer for The Flash as DC's oldest Batman yet. In a trailer aired during the Superbowl, audiences got their best look yet at Ezra Miller's long-delayed superhero film, which will be the first project to feature Michael Keaton's Batman since 1992's Batman Returns, dispelling rumors that the iconic character had been cut from the final film. The film sees the DCEU's Flash travel to an alternate timeline where his mother is still alive, eventually running into several variant heroes, including Keaton's Caped Crusader, who is well advanced in years by the time he appears in The Flash.
