The Black Adam movie just got a whole lot more interesting for fans of old comic book lore. According to star Dwayne Johnson, the movie is set to bring the Justice Society of America into the fold. Johnson has been attached to the role for the better part of a decade and, after years of waiting, the project finally has a release date and is set to begin filming next year. Now, Johnson has decided to start sharing some details as things ramp up.

Currently, The Rock is promoting his latest movie, Jumanji: The Next Level. During a recent interview, Johnson was hanging out with his co-star Kevin Hart. The comedian was lobbying hard for a role in Johnson's DC adventure, which dropped a Black Adam first look poster just days ago. The WWE Superstar revealed that the Justice Society of America will factor into his superhero epic. Johnson joked that Hart could have a role as the group's pet. Here's what he had to say about it.

"We're also gonna introduce JSA in Black Adam. So in JSA maybe there's a (role)...They have an animal, a pet."

This is a pretty major detail as it not only provides us with some insight, but it will bring the first superhero team in comic book history to the big screen. Way back before National Comics and All-Star Comics merged to become DC Comics in 1945, the two companies partnered up to form the Justice Society of America. The initial lineup consisted of Doctor Fate, Hour-Man, the Spectre, The Sandman, The Atom, the original version of The Flash, Jay Garrick, Alan Scott's Green Lantern, and Carter Hall, the original Hawkman. Superman and Batman were eventually brought into the fold as well, as was Wonder Woman.

The book stopped being published in 1951 and, once DC Comics decided to bring back the idea of a superhero team, it became what we now know as the Justice League. So the idea that Black Adam will be digging deep into DC history is telling. It certainly suggests that the movie will be, in part, a period piece. Black Adam has historically been a villain, the arch-nemesis of Shazam. However, Dwayne Johnson is positioning him more as an anti-hero. Could it be that he finds himself at odds with the JSA? It also opens up major questions about who will be positioned as the villain. Maybe they'll unite to take down a common enemy? Whatever the case, it seems quite a few Golden Age heroes are set to make their big screen debuts.

Jaume Collet-Serra (The Shallows, The Jungle Cruise) is set to direct. Dwayne Johnson also recently revealed that cinematographer Larry Sher will shoot Black Adam. There is no further word on casting at this point, but production is set to begin next summer, so information should be trickling out between now and then. We'll be sure to keep you posted as further details are made available. Black Adam is set to hit theaters on December 22, 2021. This news comes to us via Comicbook.com.
