History Fridge / Underwater

* If the monster at the end was Cthulhu, and the creatures attacking were his Deep Ones, there's a very unpleasant conclusion lurking. Deep Ones do not breed true with each other, hence their penchant for establishing surface cults and luring humans into worshiping the Great Old Ones. The Deep Ones breed with the human cultists, siring children who appear human but slowly transform into Deep Ones as they age. Not only are all the attacking creatures potential [[WasOnceAMan former human beings]], if the Deep Ones capture any of the rig workers, [[BreedingSlave their fate is likely to be very unpleasant]]. Perhaps it's a good thing the humans are so deep in the ocean the environment is instantly fatal.

** 1. One of Cthulhu's powers is that he can alter his form as he wishes.
** 2. His psychic powers do not work underwater.

* When we first meet Captain Lucien, he says that he managed to send up 22 escape modules from the Kepler Station. But at the end of the film the newspapers articles over the credits indicate that Alice and Smith were the only survivors of the incident, meaning that all the 22 modules launched from Kepler were intercepted by the creatures and destroyed.

** Along those lines, YouTuber Deusdaecon has theorized that Tian Industries is run by cultists and it's possible that the people in Nora's facility were meant as human sacrifices to the EldritchAbomination citing how less advanced the main facility was while the drill was far more advanced and intact in spite of being older. He also points out that "Tian Industries" was so named because of Lovecraf''tian'', according to WordOfGod.

* Even if more people had managed to survive the explosion and the trip, they had no way of getting more people to safety than they did. In the end, there were only two escape pods.

** Considering that it's revealed that the Franchise/CthulhuMythos is involved, the ending makes sense as it's not the first time a nuclear explosion is used against the creature. In Literature/TheTrailOfCthulhu by Creator/AugustDerleth, a nuclear bomb was used against Cthulhu. However, that story implies the victory is short-lived. If that's the case for that story, considering Tian Industries plans on getting back to drilling as soon as they can, it's clear that [[TheEndOrIsIt it's not the end of Cthulhu as viewers may think]].

* In his video about the movie, ''FoundFlix'' points out how weird it is that Tian Industries intended to resume deep sea drilling, even after logically have known about the creatures, and he theorizes that this means that they were not only ''aware'', they '''wanted''' to find them.

* By the end, [[spoiler: one must wonder what happens to Smith and Haversham. There's no way Tian Industries would let them go or let them live now that they know that there are creatures living under the deep.]]
