Official teaser...

I guess the opening scene will bear a resemblance to The Mummy Returns? Johnson's career has come full circle.

Real teaser.

CinemaCon trailer description:

Beginning with futuristic ships flying “against a snowy mountain landscape.” We then get a shot of Pierce Brosnan’s Dr. Fate, who says, “Black Adam, what are the powers that have been given to you? Loving but heartache?”

Johnson’s Black Adam then says “that he was born a slave, “then I was reborn a god.’ Black Adam can be the savior of the world, or its enemy.” Things quickly kick off, with Black Adam seen “destroying helicopters and coming in contact with what looks to be mercenaries.” Even walking away from an explosion in true action hero style. Understandably, the mercenaries are scared of the antihero in front of them, especially when he “catches a rocket.”

After some action shots of the Justice Society of America, Black Adam shows us what makes him so different from the likes of Superman and Batman. Aldis Hodge’s Hawkman stands face-to-face with Black Adam and says, “There are heroes and villains; heroes don’t kill people.”

“Well, I do,” Black Adam replies. The crowd cheers. The hierarchy of power has indeed changed.
