The report adds that Johnson said that he isn’t sure yet whether he’ll take the role of hero Shazam or his nemesis Black Adam in the movie, noting that he has “always been a fan of anti-heroes,” and that Black Adam — an earlier version of Shazam from Ancient Egypt who has become an anti-hero in recent years — has always been one of his favorite DC characters.

No matter which role he takes, he said that he is “putting my heart and soul and my bones” into it, according to the Associated Press report. To date, no Shazam project has been officially announced by Warner Bros., although with no less than nine mystery DC Entertainment movies scheduled between 2016 and 2020, it wouldn’t be lacking a potential release date.
