More specifically - Is Dwayne Johnson playing Shazam?
If you check out the interview below with +Total Film then the answer can only be yes. Johnson says that he and WB will announce something involving a DC superhero. From the hints the actor dropped in the interview it's highly likely the character is Shazam. He says the superhero has "the power of Superman" and added "Just say the word."
Hmm, interesting indeed.
