Black Adam spoilers follow.
If you've seen Black Adam by now, you'll know it saves its biggest surprise for the mid-credit scene which has got DC fans very excited.
The mid-credit scene sees Black Adam (Dwayne Johnson) hanging out in Kahndaq when he's given a warning by Amanda Waller (Viola Davis): leave Kahndaq and he will be stopped... permanently.
He knows that there's nobody on Earth that can stop him though, but Waller has a trick up her sleeve and there is somebody in the universe that can stop him. This is your final chance to avoid spoilers.
It is, of course, none other than Superman (Henry Cavill) who has officially returned into the Worlds of DC fold after those premature rumours of his departure.
Talking to ComicBook.com, Dwayne Johnson revealed that it was actually pretty straightforward to get Cavill to don the cape again. "Well, I've known Henry for a long time. We're buddies," he explained.
"My longtime business partner, Dany Garcia, she has been a big advocate for Henry. She's managed Henry's career over the years. It came down to, dude, we love Superman. There is new leadership about to happen in Warner Brothers. Here's an opportunity.
"On our end of Black Adam, we will do everything we can to pay homage and respect to the mythology of Black Adam and build him as being the most powerful and unstoppable force on this planet.
"And if we do our job right, at the end of the movie, then in comes not only the most powerful and unstoppable force in the entire universe in Superman, but also the one that the fans want."
Superman's appearance is all part of the "new era" of the Worlds of DC that Johnson is helping to build where the fans will know "they're not ignored".
"When it comes to Superman, I don't know if there's any other person on the planet who loves and embodies the mythology, the ethos, and everything of Superman than Henry," Johnson continued.
"And so I'm so happy that it all came together. I'm so happy the fans are losing their minds over it. And I'm so happy that there is a new shift in this DC universe. And Superman is back."
We still don't know yet if there will be a Black Adam 2, but if a sequel does happen, the likes of Noah Centineo and Aldis Hodge certainly seem up for a return too.
Black Adam, Superman and the Justice Society? Now that's a combo to get fans excited.
Black Adam is out now in cinemas.
