Dwayne Johnson has been cast as Black Adam for an upcoming Black Adam feature film from New Line Cinema and Warner Bros. Set in the DC Extended Universe, Black Adam is scheduled for release in December 2021. Dwayne Johnson took to his Twitter space to make the news official - “You’ve waited long enough. As have I, thousands of years to be exact. The hierarchy of power in the DC UNIVERSE is about to change. The man in black comes to crush them all. Join us now for the worlds first.” He also added “I’m honored to join the iconic #DCUniverse and it’s a true pleasure to become Black Adam,” he wrote. “Black Adam is blessed by magic with the powers equal to Superman, but the difference is he doesn’t toe the mark or walk the line. He’s a rebellious, one-of-a-kind superhero, who’ll always do what’s right for the people — but he does it his way. Truth and justice — the Black Adam way. This role is unlike any other I’ve ever played in my career and I’m grateful to the bone we’ll all go on this journey together.” 
 
Black Adam is a fictional supervillain appearing in American comic books published by DC Comics. Created by Otto Binder and CC Beck, the character is one of the archenemies of the superhero Captain Marvel (DC Comics), and the nemesis of the Shazam Family. Black Adam first appeared as a one-time villain for the first issue of Fawcett Comics' The Marvel Family comic book (December 1945). However, Black Adam was revived as a recurring character after DC Comics first licensed and then acquired the Fawcett characters and began publishing Shazam/Formerly Captain Marvel Family stories under the title Shazam! in the 1970s. 
 
As originally depicted, Black Adam was a corrupted, ancient Egyptian predecessor of Captain Marvel, who fought his way to modern times to challenge the hero and his Marvel Family associates. Since the turn of the 21st century, however, Black Adam has been re-defined by DC Comics writers Jerry Ordway, Geoff Johns, and David S. Goyer as a corrupted antihero attempting to clear his name and reputation. Featured roles in such comic book series as Justice Society of America (JSA), Villains United, Infinite Crisis, and 52 have elevated the character's prominence in the DC Universe.
