Well, while answers are blowing in the wind at the moment, we at least are able to confirm that The Rock will be in multiple DC movies because New Line is giving Black Adam his own solo movie in addition to the Shazam film.
Note to studio executives: When you have The Rock in your corner, you use him as often as possible.
With the DCEU stringing Dwayne Johnson along as its proposed Black Adam, fans of both the blockbuster action star and the Shazam property kept wondering WHEN we’d see Rocky as Black Adam, the villainous anti-hero who often fights Shazam.
