BLACK ADAM. A complex psychology, motivated by bad ass dominance with a devilish charm. This'll be fun. #Teth #Shazam https://t.co/zE4wtri3sT

Before Johnson announced his character for the filmic adaptation of Shazam, it was uncertain whether or not he’d play the protagonist or antagonist. Black Adam, an anti-hero and major nemesis of villain Shazam, was an earlier version of Shazam that hailed from Ancient Egypt.

Hiram Garcia will be producing the project, which will have a script by Darren Lemke, according to The Hollywood Reporter. It’s unknown who will be helming the picture or who will take on the part of Shazam.

Shazam is but one of nine DC Entertainment titles that will be hitting theaters between 2016 and 2020.
