Now thanks to a reddit user, it's become known San Andreas has a Black Adam Easter Egg.
Spoiler follows for San Andreas.
Johnon's co-star in San Andreas, Alexandra Daddario, plays Blake and in once scene refers to Dwayne Johnson as "this generation's Adam, but black."
Obviously, it's a reference to Johnson as Black Adam.
Who knows though, maybe it's a hint that San Andreas director Brad Peyton will be reteaming with Dwayne Johnson on Shazam as well.
Shazam has a planned 2019 release date, but on more than one occasion, Dwayne Johnson has stated the movie will be released earlier; as of yet, no actor has been cast as Shazam.
(It probably should be noted San Andreas is a WB movie as well.)
