"Big Mouth" Dwayne Johnson spoils "Black Adam" and the battle with Superman becomes a reality

Before the release of "Black Adam", the leading actor Dwayne "The Rock" Johnson has been claiming for months that "the power level in the DC universe will change" after the film is released. However, recently he himself spoiled the content of the film's post-credits Easter egg.

According to Johnson, the film will connect Black Adam to the previous DC film series through a post-credits scene. In this scene, Black Adam will face off against Superman played by Henry Cavill. Henry Cavill has been playing Superman in Warner-released DC films since Man of Steel in 2013. There have been unconfirmed rumors that Warner Bros. and Henry Cavill will no longer work together in the future, but it seems that this situation may have changed.

Johnson said: "Over the years, audiences have been very enthusiastic about this... We've established Black Adam as the most powerful and unstoppable force on our planet. But fans, like us, have been eager to know, where is the most unstoppable force in this 'universe'? Where is he?"

"Just like I've been working for 15 years to get Black Adam out there," Johnson continued, listing off the other members he's working with on the Seven Bucks team, saying they've "all been fighting for this moment." As for Henry Cavill returning as Superman, Johnson said, "I say: 'Welcome home.'"

Regarding Henry Cavill's return, Warner Bros. and Henry Cavill himself have not announced whether there will be other "Superman" movies in the future. This may just be an interesting cameo, or it may be a signal of a new era for the DC movie universe. Johnson said in a recent interview that he hopes to see the two characters have an actual fight in future movies.

Black Adam will be released in theaters on October 21.
