After the surprising success and quality of Shazam, fans were immediately excited for its spiritual prequel Black Adam, starring none other than Dwayne "The Rock" Johnson. The movie gained some immediate hype when reports of JSA characters appearing surfaced and they were later confirmed when He-Man star Noah Centineo was cast as Atom Smasher. It's a good thing that the movie was announced with a late 2021 release because it looks like shooting won't start till next year.
The Hollywood Reporter states that Dwayne Johnson will finish filming Netflix's Red Notice first, as soon as they can shoot again. Unless they can shoot again later this year, they will likely finish shooting Red Notice later than expected due to COVID-19 so there's a good chance that The Rock's first superhero movie won't be coming out until 2021.
In defense of this, just because Black Adam will be shooting next year doesn't mean that it will be delayed. Granted, a delay might be warranted so that the movie won't have to be rushed and end up being mediocre but movies can usually be completed within a few months, minus some reshoots here and there.
Most comic book fans like the Black Adam character a lot since he is often portrayed as one of the more sympathetic DC villains around, even if some interpretations make him a little too evil. Still, the character is beloved by fans and is sometimes more popular than Shazam himself so expect more excitement for this movie.
Dwayne Johnson for the casuals and JSA for the hardcore? It's a DC match made in heaven.
Black Adam is currently slated for a December 22, 2021 release.
