Logically, this suggests the Schumacher movies are no longer canon within Burton's continuity. 'The Flash,' though is changing that. Based on the little footage we see of Keaton in the trailer, it appears he's living in a Burton-esque Gotham, and maintains the same brutal sensibilities that defined his character, as opposed to the more lighthearted fare of Val Kilmer and George Clooney. This went against Keaton's goals, and he later said in an interview (now archived on The Wrap), 'At one point, after more than a couple of meetings where I kept trying to rationalize doing it and hopefully talking into saying 'I think we don't want to go in this direction, I think we should go in this direction.' And he wasn't going to budge.' Val Kilmer replaced Keaton, and at the time, it appeared 'Batman Forever' and 'Batman & Robin' took place in the same universe as Burton's movies, as evidenced by characters like Gordon and Alfred being played by the same actors.

After 'Batman Returns,' Joel Schumacher was brought on to replace Tim Burton and take the franchise in a lighter direction. Of course, Keaton's Batman exile was intentional. While Ben Affleck's Batman will appear, he'll be replaced by the Caped Crusader played by Michael Keaton, last seen in 1992's 'Batman Returns.' It's been over 30 years since Keaton suited up as the Dark Knight, but fans are delighted to see him return. As we can see from 'The Flash' trailer, we'll get a new last child of Krypton in the form of Supergirl (Sasha Calle), leading the charge against General Zod (Michael Shannon).
