As 'Batman vs. Superman' very clearly teases the upcoming 'Justice League' crossover (the subtitle is 'Dawn of Justice' after all), we all sort of assumed that The Rock's long-teased 'Shazam!' movie would fit into that blueprint somehow. Even The Rock himself tweeted the art above of his character, Black Adam, fighting both Shazam and Superman. But, now it seems that 'Shazam!' will be operating independently from the rest of the other DC superheroes at Warner Bros.
