Dwayne "The Rock" Johnson has been teasing a superhero role for, oh, about forever and we're finally getting closer to figuring out who he'd actually play. While on tour in Mexico promoting 'Hercules,' Johnson did confirm to the Associated Press that he's starring in the Warner Bros. adaptation of 'Shazam' but that he (or they) hadn't yet decided if he would play the hero himself, or the film's villain, Black Adam.

Later in that same interview, Johnson says that Black Adam is one of his favorite superheroes (alongside Green Lantern), so it certainly sounds more like Johnson knows which role he wants to play, but that he can't announce it yet. Luckily, he did confirm that an official announcement will be made soon, so we can stop with the coy tweets and hints and just get to Shazam-ing things.

He was asked how, if at all, he will fit into the new 'Justice League' universe that's launching with 'Batman vs. Superman' and it sounds like he wasn't sure. Shazam himself doesn't fit neatly into a Justice League lineup that you'd expect would be made up of Superman, Batman, Wonder Woman, Aquaman, Green Lantern and Flash.`But, it's possible that his character could be introduced in 'Batman vs. Superman' if for no other reason than to set up a sequel. (Also, 'Guardians of the Galaxy' haven't yet appeared in an 'Avengers' movie, but they're still very much tied into the Marvel Cinematic Universe as a whole.)

When 'Shazam' would hit theaters, remains to be seen but Warner Bros. recently set nine release dates for DC films, so at the very least, the studio has an idea of when that film would hit theaters. The Rock himself is busy with 'San Andreas' on the way and a recent deal to star in two new 'Journey 3D' sequels.
