The DC Multiverse concept has been explored on the small screen in The CW’s ArrowVerse quite a bit.
It was recently revealed that both Ben Affleck and Michael Keaton will be appearing as different versions of Batman in The Flash movie, a project that has been gestating for some time.
While Micheal Keaton’s inclusion certainly signaled that was the plan for The Flash, Muschietti is not being coy about the fact that the multiverse is going to be a big part of his next project.
For example, Robert Pattinson is playing the lead in The Batman, which is set to hit theaters next year.
