The Mummy is intended to kick off the Dark Universe (a shared universe based on Universal’s classic horror franchises), and fans have already noticed one of the Easter Eggs that hint at a larger world than the one presented by the undead Egyptian threat. What appears to be part of a Gill Man’s anatomy can be seen briefly in a trailer, referencing the titular Creature from the Black Lagoon.
ComicBook.com and Twitter user TallyDude have observed that an official advertisement for The Mummy features a blink-and-you’ll-miss-it look at a sample of a creature in a laboratory. This is the hand of a Gill Man, the Creature that resides in the infamous Black Lagoon:

There’s an in-story reason for this reference to exist where it does – Dr. Henry Jekyll/Mr. Edward Hyde (Russel Crowe) is a crucial member of a secretive organization known as the Prodigium, which is meant to keep the existence of monsters secret, or in a worst-case-scenario, limit the amount of damage that is actually done. (So basically, these guys are the Dark Universe’s answer to the MonsterVerse’s Monarch.) Since the Prodigium have determined that there’s a science to all these monsters, it only makes sense that they’d be closely studying the ones that they neutralize.
The Mummy rises on on June 9, 2017. The movie’s cast includes Tom Cruise, Sofia Boutella, Russel Crowe, Annabelle Wallis, Jake Johnson, Courtney B. Vance, and Javier Botet. Two subsequent installments of the Dark Universe will be released on April 13, 2018 and February 15, 2019. Other projects that are in development for the setting include reboots of Van Helsing, Creature from the Black Lagoon, The Bride of Frankenstein, The Invisible Man, and Wolf Man.
