Dwayne “The Rock” Johnson teased the release of his film Black Adam. The teaser is drawn by Jim Lee and BossLogic with the date of December 22, 2021. Lee’s image has the character looking much more like Johnson than his regular comic depiction. The film has been in production, with Johnson attached for years and pre-dated Shazam.

Black Adam is a nemesis of Shazam whose film was a moderate hit for DC Comics and Warner Bros. A sequel is being worked on for that movie.

In the post, Johnson said:

The Man in Black ⚡️
Like most kids growing up, I dreamed about being a superhero. Having cool superpowers, fighting for what’s right and always protecting the people.
It all changed for me, when I was 10yrs old and was first introduced to the greatest superhero of all time – SUPERMAN.
As a kid, Superman was the hero I always wanted to be.
But, a few years into my fantasy, I realized that Superman was the hero, I could never be.
I was too rebellious. Too rambunctious. Too resistant to convention and authority.
Despite my troubles, I was still a good kid with a good heart – I just liked to do things my way.
Now, years later as a man, with the same DNA I had as a kid – my superhero dreams have come true.
I’m honored to join the iconic #DCUniverse and it’s a true pleasure to become, BLACK ADAM.
BLACK ADAM is blessed by magic with the powers equal to SUPERMAN, but the difference is he doesn’t toe the mark or walk the line.
He’s a rebellious, one of a kind superhero, who’ll always do what’s right for the people – but he does it his way.
Truth and justice – the BLACK ADAM way.
This role is unlike any other I’ve ever played in my career and I’m grateful to the bone we’ll all go on this journey together.
BLACK ADAM

It’s an almost given that Shazam and Black Adam will meet in a future film after Johnson’s debut film.
