Though the film has gone through a period of uncertainty, Warner Bros.' The Flash solo film is still happening.
At one time, Ezra Miller seemed uncertain about his future as the Scarlet Speedster, but he recently told W Korea that both Fantastic Beasts 3 and The Flash films are "absolutely confirmed."
Spider-Man: Homecoming screenwriters Jonathan Goldstein and John Francis Daley were set to direct The Flash, but recent reports say they are out. Andy Muschietti, director of It and It: Chapter 2, may take over as director, though Muschietti hasn't confirmed or denied those claims.
Christina Hodson is reportedly in talks to write a new version of The Flash's script. Hodson also penned the scripts for 2018's Bumblebee and the upcoming Birds of Prey film.
Miller first appeared as Barry Allen/The Flash in 2016's Batman V Superman: Dawn of Justice. He had a starring role as the Flash in 2017's Justice League and made an appearance in 2016's Suicide Squad.
The Flash is expected to star Ezra Miller as Barry Allen and Billy Crudup as Henry Allen. As of now, The Flash does not have a release date.
