It was previously reported that The Flash will begin filming at Warner Bros. Studio Leavesden in the UK on April 26. The film will be employing a largely local crew while already in the UK are the film's director and producer, Andy and Barbara Muschietti, respectively.

The Flash is speculated to be a loose adaptation of the 2011 limited comic book series Flashpoint by Geoff Johns and Andy Kubert, in which Barry races back to the past to save his mother, only to create an alternate timeline in the process. Ben Affleck will reprise his DCEU role as Batman in the film for the first time since Justice League, with Muschietti describing Affleck's Caped Crusader as "a very substantial part of the emotional impact of the movie."

Directed by Andy Muschietti from a script by Christina Hodson, The Flash stars Ezra Miller, Michael Keaton, Ben Affleck and Billy Crudup. The film arrives in theaters Nov. 4, 2022.
