This is exciting news for the film, which will deal with alternate timelines and features multiple versions of Batman (and likely some surprises as well). The Flash movie features Ezra Miller as he reprises his role as the DCEU’s Scarlet Speedster/Barry Allen, who he first portrayed in Batman v Superman: Dawn of Justice, Justice League, and Zack Snyder’s Justice League.
The filming of The Flash has resulted in plenty of leaks, but this seems to be the meatiest one yet.
Newly leaked The Flash photos show off Ezra Miller’s Barry Allen, another glimpse at Supergirl’s full costume, Michael Keaton’s Batmobile, and a familiar Batcave.
He also played the hero in a cameo appearance on The CW’s Crisis on Infinite Earths crossover event, where he got to meet Grant Gustin’s version of Barry Allen.
