Dwayne "The Rock" Johnson will officially join the DC Extended Universe once Black Adam premieres on October 21. Since we're talking about The Rock, the Red Notice star has spent the past year talking up his upcoming role in the DCEU. He has mentioned how Superman can't beat Black Adam as well as a potential crossover with the DCEU's Wonderwoman and the MCU's Deadpool. Now, Johnson just poured fuel into the raging rumor fire by basically "confirming" that Henry Cavill's Superman might appear in Black Adam.

Everything started when a fan replied to one of Johnson's tweets and brought up how he would love to see Black Adam and Superman in the same movie, to which The Rock had a positive response.

From back in the day when I was wrestling in flea markets for $40 bucks a match, all the way to now.
I’ve learned to always listen to the audience because they will always lead you to where you need to go.
I hear you & I always got you 👊🏾😉#BlackAdam @SevenBucksProd https://t.co/gqFlDwb8ud

Johnson's statement doesn't confirm anything, but it doesn't hurt to speculate. Both Cavill and Johnson are at least familiar with each other and have posted several photos together. Not to mention, they also share the same agent. More importantly, Warner Bros. Discovery's new CEO, David Zaslav, reportedly claims that he wants to revamp the DCEU, emphasizing the importance of Superman. Cavill's portrayal of the Man of Steel is a fan-favorite. If Cavill is serious about returning as Superman, a Black Adam cameo would be the perfect way to "restart" the DCEU now that Zack Snyder has moved on to partner with Netflix.

Chronologically speaking, it wouldn't make sense for Black Adam and Cavill's Superman to fight in Black Adam. Black Adam will presumably be set before modern times given the appearance of the Justice League's precursor, the Justice Society of America. For a fight between these two DC powerhouses to happen, it would have to take place in a sequel with a post-credits scene cameo setting it up. This would be the ideal scenario, but we can never really know if and when it will happen.

Superman may or may not make a cameo in Black Adam in October, but the DCEU will be wasting an opportunity if its plans for the Kahndaq anti-hero do not involve a Superman vs. Black Adam showdown.
