A bunch of set pics from The Flash movie featuring Ezra Miller has leaked online where fans are speculating all kinds of different theories which possibly might include the Reverse Flash.
The set pics show the Ezra Miller Barry Allen apparently talking to an alternate version of himself, where the alternate version happens to be wearing a yellow jacket with white sneakers with a yellow swoosh symbol.
The Flash Ezra Miller leaks:
A lot of fans think the pics show the Ezra Miller Barry Allen from the DCEU talking to the Barry Allen Flash from the Michael Keaton Batman universe, where more than a few fans have professed their disappointment the Michael Keaton Batman universe version of The Flash isn't played by a different actor.
However, what if that isn't the Michael Keaton The Flash, but the Reverse Flash? Maybe in the Michael Keaton timeline, Eobard Thawne is actually the good guy - The Flash - while Barry Allen becomes the Reverse Flash?
It would actually be a fresh take on The Flash mythos as I don't ever believe Barry has been the Reverse Flash (correct me if I am wrong).
The Flash crashes into parallel dimensions
Still, another possibility is that Barry travels back in time during the movie and talks to his younger self; however, I'm leaning more toward the theory of the alternate universe Barry Allen being the correct one.
It's also rumored that Grant Gustin will appear in the flick in a brand new scene, different than the scene between Gustin and Miller from Crisis On Infinite Earths.
The Flash has a November 4, 2022 release date directed by Andy Muschietti with the flick described as following The Flash breaking the bonds of physics and crashing into parallel dimensions leading to encounters with different versions of the DC superheroes including Batman and Supergirl. It's also said Barry travels back in time to save his mother and reverse her death which causes drastic changes to the timeline that sees The Flash connect to new universes, with the Michael Keaton Batman '89 universe, and others.
Ben Affleck also stars as Batman, Sasha Calle as Supergirl, Kiersey Clemons as Iris West, with Ron Livingston as Henry Allen, and Maribel Verdú as Nora Allen.
