Jordan Peele was originally offered the chance to direct the film when it was first announced in 2017, but Peele declined, saying, "I'm not a fan of superhero movies and I'd hate to take that chance away from a director who is passionate about them."
While Black Adam and Captain Marvel speak the same name of the wizard Shazam as an acronym to activate their powers, in the case of Captain Marvel the acronym stands for the wisdom of Solomon, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles, and the speed of Mercury. In the case of Black Adam, the acronym stands for the stamina of Shu, the swiftness of Horus, the strength of Amon, the wisdom of Zehuti, the power of Aton, and the courage of Mehen.
Dwayne Johnson once asked his fans which character he should play, superhero Shazam or supervillain Black Adam. His fans chose Black Adam.
Black Adam was originally going to appear in Shazam! (2019), but it was later decided he would debut in his own film.
The film originally received an R rating due to several gruesome death scenes. A majority of these deaths had to be cut before the film could receive the more commercially viable PG-13 rating.
