Michael Keaton is the right age for The Dark Knight Returns to be made and this could even be done alongside the current slate of DC Universe movies. After all, The Dark Knight Returns is a separate universe in the graphic novel. Here to, Warner Bros. could capitalize on bringing back the Batman that everyone remembers for kicking off comic movies. Hell, I’d even be for Tim Burton coming back to put his spin on it just to keep it as a cap to his version’s trilogy. Would it not be cool to see Keaton suited up one more time as Batman? Or that stylized and cool Batmobile once more in action?
Granted, it would take some writing to be done because, Joker died at the end of the first Batman movie and Jack Nicholson is for the most part retired (unless something spectacular comes along), but it could still work. It wouldn’t be just like the graphic novel but I’m pretty sure a cult of Joker and the Superman fight could all be done. Also, if done right, this could even kick off a Batman Beyond movie franchise where Keaton could reprise the roll of Bruce Wayne but not have to suit up.
Warner Bros. should be on the phone with Keaton, Burton, Pfeiffer, and whoever else needed to make this happen. Especially since the current DC Universe seems to be being picked apart by the critics at large (unfairly I would say but the fact is it is happening). The Dark Knight Returns as a movie and done in this way could be huge though!!!
