In the first Black Adam footage, unveiled at DC Fandome on Saturday, Johnson takes on the power of Shazam as one of DC comics' baddest bad guys.

"The truth is I was born to play Black Adam," Johnson said at the virtual fan event before the footage played, promising viewers huge action sequences and "breathtaking 'holy shit' scenes.".

Johnson revealed an early scene from the film, in which archeologists make the mistake of zapping Black Adam with a bolt of lightning.

Created by Otto Binder and CC Beck in 1945, Black Adam was a bad guy in the original Captain Marvel series published by Fawcett comics.

Johnson was originally supposed to appear in that film, but Black Adam was spun off into its own film, which he describes as a "passion project."
