The Abyss

Based on the novel by Michael Crichton, Sphere involves a team of scientists investigating a spaceship discovered at the bottom of the ocean, where they encounter strange phenomena. The psychological and sci-fi elements should intrigue fans of The Abyss.

The Meg presents a group of scientists exploring the Mariana Trench who encounter the largest marine predator that has ever existed - the Megalodon. This deep-sea adventure with its colossal threat carries shades of the tenseness found in The Abyss.

Pandorum's tale of astronauts waking up with no memory aboard a seemingly abandoned spaceship offers a similar blend of sci-fi suspense and horror, with claustrophobic settings and unknown terrors that fans of The Abyss might find appealing.

Although not set underwater, The Core deals with a group of scientists who travel deep into the Earth to set off a series of nuclear explosions in order to restart the planet's core. The themes of claustrophobia and an otherworldly environment are common with The Abyss.

A sci-fi horror film set deep underwater, Leviathan features a crew of ocean miners who come across a Soviet ship that sunk years before, carrying a deadly secret. The claustrophobic setting and alien-like threats echo the intense, otherworldly atmosphere of The Abyss.

Directed by Sean S. Cunningham, DeepStar Six centers around an underwater US Navy facility encountering a monstrous threat, much like the suspenseful underwater encounters in The Abyss. Fans of subaquatic tension and creatures will definitely appreciate this one.
