Christina Hodson wrote the The Flash's script, with Michael Disco and Marianne Jenkins on board as executive producers. Plot details are still under wraps, but the story is expected to be at least partially influenced by the Flashpoint comic book arc.
In addition to Calle, Ezra Miller as Barry Allen and Michael Keaton and Ben Affleck as their respective takes on Batman, Kiersey Clemons will reprise the role of Iris West, and Zack Snyder's Justice League star Ray Fisher recently indicated that there was still a chance he could appear as Cyborg (we seriously doubt that happens at this stage).
The Flash is currently shooting in The UK, and is scheduled to race into theaters on November 4, 2022.
