The Flash isn't racing into theaters anytime soon.

Warner Bros. is delaying the start of production on the still untitled standalone movie centered on the speedster character, played by Ezra Miller in "Justice League."

According to Variety, even though the film never received a formal greenlight, it was due to begin filming in March. Now, filming is more likely to commence in late 2019, for a 2021 release.

The delay is reportedly all Harry Potter's fault, or we should the Harry Potter universe. Miller has a key role in the "Fantastic Beasts" franchise, and the third film is set to begin filming in July. That would've caused major scheduling headaches had The Flash movie started this spring.

Earlier this year, Warner Bros. replaced director Rick Famuyiwa ("Dope"), who had left the project due to creative differences, with "Spider-Man: Homecoming" writers John Francis Daley and Jonathan Goldstein.

The DC Extended Universe has plenty going on, even with The Flash's delay. "Aquaman" and "Shazam" are coming soon, and everyone is excitedly waiting for "Wonder Woman 1984" in November 2019.
