Dwayne "The Rock" Johnson is confirmed to take on the role of villain Black Adam in DC's upcoming adaptation of "Shazam." However, Shazam is not Black Adam's sole nemesis in the comic books, and fans are excited to see him potentially go head to head with another superhero: Superman.

Speaking with Total Film, Johnson teased a possibility of Black Adam crossing into other movies in the expansive DC Extended Universe, particularly in "Man of Steel 2." "It was all agreed that the worlds are all interconnected... One day you will see Black Adam go at it with Superman or Batman or any of the DC characters," Johnson said. "But that said, there's a great independence to Black Adam from the DC world, allowing us to inject, not only viciousness, but also winking humor"

The "Shazam" movie won't be out until 2019, so there is a chance developments could change over at DC and Warner Bros. that might open up a possibility for Black Adam to appear in the highly-awaited "Man of Steel 2."

According to Batman-News.com, both Henry Cavill and Dwayne Johnson share the same manager, Dany Garcia, who shared a photo of both stars having a drink during the holidays. If this is not an indicator of a possible project with the two in the future, we don't know what else is. Garcia himself was also the one who confirmed that "Man of Steel 2" is being developed over at Warner Bros.

More recently, Johnson did further teasing about his upcoming projects in the DCEU. He took to Facebook to share that he had a "strategic meeting with the heads of DC Comics" about the entire DCEU. He added that what DC is planning is something fans have been waiting for, including "the most ruthless villain/anti-hero of all time finally coming to life."

Johnson also revealed that there are going to be "tonal shifts" in future DCEU movies. Although this wasn't detail yet, but fans will probably know soon once "Justice League" comes out.

In the meantime, Johnson will appear in "Fast & Furious 8."
