With the success of Gareth EdwardsGodzilla in 2014, plans were set in motion to bring back all of Hollywood’s giant monsters to the silver screen, revamping the shared universe created with the original Japanese kaiju and King Kong films for the modern day. Kong: Skull Island is next in line, with a March 2017 release date quickly approaching. Fans at NYCC were given cool posters for the movie, featuring a grid map of the titular island with the caption “Bring the Truth to Light.” But there’s a little more to the map than meets the eye.

Some clever folks at ComingSoon.net recently found the secrets lurking in what seems to be a mostly innocuous picture. In normal light, the poster looks like a realistic satellite photo of the mysterious island Tom Hiddleston and Brie Larson journey to.

But if you shine a blacklight onto it (literally bringing the truth to light), you get something that looks like this:

The poster has secret notations from MONARCH, the secret government organization introduced in the 2014 Godzilla film that was formed to hunt down and study “massive unidentified terrestrial organisms.” The radioactive insectoid M.U.T.O. in Godzilla was one of these. Superimposed onto the island itself is what looks like the skeleton of some huge lizard creature — possibly another organism MONARCH is searching for. Could this be the reason the explorers journey to Skull Island in the first place? Is finding King Kong just an unexpected bonus?

Near the bottom of the poster, some writing reads:

His mouth is fire; his roar the floodwater; his breath is death. Enlil made him guardian of the Cedar Forest, To frighten off the mortal who would venture there. BUT WHO WOULD VENTURE THERE?

A quick Google search for “enlil cedar forest” gives us a brief history of Sumerian religion, but what’s important is that the Sumerian god Enlil created a monster named Humbaba to guard the Cedar Forest, the home of the gods, so that no human would try to get up to any shenanigans. Could Humbaba be the name of the giant skeleton in the poster? Is this what the team of MONARCH researchers are hoping to find?

Kong: Skull Island is directed by Jordan Vogt-Roberts, also stars John Goodman, Samuel L. Jackson, and John C. Reilly, and hits theaters March 10, 2017.
