However, this May, The Flash TV series star Tom Cavanaugh dissed Zack Snyder for overlooking Grant Gustin as the movie version of The Flash.
Back in April, producer Deborah Snyder teased that Cyborg (Ray Fisher) will be featured in The Flash movie.
We don’t know for sure when these roles will be filled, or when exactly production will begin, but Ezra Miller teased one of his biggest influences in researching The Flash, comic book legend Grant Morrison.
The biggest opportunity for any sort of crossover is with The Flash, which has Ezra Miller starring as the movie version of Barry Allen and Grant Gustin heading into his third season as the speedster on The CW series of the same name.
