While many of these masterpieces do dabble in horror, rest assured there are a few delightful surprises lurking within as well.

If you’re on the hunt for less familiar Sci-Fi films to expand your collection, we’ve prepared an extensive list of top-notch Sci-Fi movies that may be new to you. Why not take a peek and explore? Without any more delay, let’s get started (a little joke about water is intended).

1. ‘Underwater’ (2020)

Beneath the vast, mysterious depths of the ocean, I find myself part of a dedicated group of marine researchers. We’re in a desperate struggle for life after a catastrophic earthquake shatters our underwater laboratory, plunging us into a world where time is running out.

In contrast, the treacherous waters seem tame when compared to an ominous threat that was stirred by the earthquake – an unyielding, voracious being risen from the depths.

2. ‘DeepStar Six’ (1989)

Under the sea’s depths, marine biologists are setting up foundations for submarine habitats. Scarpelli (Nia Peeples) insists on a thorough investigation of the underwater bluffs and warns Dr. Gelder (Marius Weyers) about potential hazards, recommending that the Navy be informed.

As a diehard film enthusiast, I’d rephrase it like this: Eager to avoid guesswork, I, Dr. Gelder, bravely force my way into an underwater grotto. Once an entry is made, I set out underwater sensors to explore the cave, but their signal mysteriously vanishes. Intrigued, I dive in to retrieve them, only to be caught off guard by a terrifying deep-sea beast.

3. ‘The Abyss’ (1989)

In James Cameron’s 1989 science fiction suspense film, “The Abyss,” a group of civilians who specialize in underwater exploration are called upon to help find a sunken nuclear submarine located at great depths beneath the sea.

As they delve further into the depths, they struggle against the threats of the dangerous surroundings and meet enigmatic underwater alien creatures whose existence alters their perception of life and our role in the cosmos.

4. ‘Sphere’ (1998)

A team composed of a psychologist named Norman Goodman, portrayed by Dustin Hoffman, a biochemist called Beth Halperin, who is played by Sharon Stone, and mathematician Harry Adams, represented by Samuel L. Jackson, plunge into the Pacific Ocean to scrutinize an ancient spacecraft submerged on the seabed.

Unveiling its mysterious secrets, they stumble upon a deadly alien assassin. Stranded underwater and losing their comrades, the terrified survivors grapple with an astonishing truth hidden deep below the surface.

5. ‘Dagon’ (2001)

Following a tragic boating mishap, a youthful pair ends up in a rundown Spanish fishing hamlet, abandoned by time. As they wander through their chilling environment, it doesn’t take long for them to discern that this place hides a disturbing truth.

The villagers are being affected negatively by a sinister, old marine spirit and its fearsome half-human offspring.

As the pair explores further into the village’s secrets, they become entangled in a network of local legends, traditional religious practices, and spine-tingling supernatural events that stem from an old seafaring folklore reminiscent of Lovecraftian tales.

6. ‘Below’ (2002)

In the film “Below” (2002), during World War II, an American submarine rescues three individuals from a sunken British hospital ship. As the voyage continues, the sailors encounter a string of progressively strange and inexplicable occurrences.

They start to believe the ship could be haunted, and the recent travelers may have something to do with the strange events happening on board.

In the throes of suspicion and unease, I find myself steering through perils that lurk both on the surface and beneath the ocean’s depths – a relentless foe above and eerie, otherworldly threats below. The boundary between fact and fantasy grows hazy, testing the very limits of my crew’s psychological fortitude.

7. ‘Voyage to the Bottom of the Sea’ (1961)

In “Journey to the Depths of the Ocean,” Admiral Harriman Nelson reveals an advanced nuclear submersible equipped with a remarkable “glass front” design, providing a clear underwater perspective.

During their inaugural journey to the North Pole led by Captain Lee Crane, accompanied by his wife Cathy Connors, scientist ally Admiral Lucius Emery, and notable guests such as politicians and Dr. Susan Hiller, an unexpected blast-like noise startles them. Upon rising to the surface, they are left astonished by the fiery spectacle overhead.

As a movie buff, I found myself drawn into a gripping tale where it’s revealed that our Earth’s mysterious and potentially lethal Van Allen radioactive belt has inexplicably ignited, placing our planet in grave danger. With just sixteen tense days remaining, it falls upon me, Admiral Nelson, and my dedicated crew to embark on an urgent race against time. Our mission: to reach the exact spot where we can launch a missile capable of neutralizing this threat, before it’s too late, and save our world.

8. ‘Leviathan’ (1989)

In the year 1989, a group of underwater mining experts led by oceanographer Steven Beck, in the movie “Leviathan”, stumbled upon the wreckage of a Soviet ship at the bottom of the sea. Yet, their expedition soon transformed into a horrifying ordeal as they came face-to-face with a monstrous, genetically-mutated creature born from an ill-fated experiment.

The team, consisting of actors like Peter Weller, Ernie Hudson, Richard Crenna, and Daniel Stern, becomes embroiled in a lethal game of hide-and-seek with a terrifying creature lurking at the bottom of the sea.

Under the guidance of director George P. Cosmatos and featuring groundbreaking creature effects by famed artist Stan Winston, “Leviathan” was likened to iconic Sci-Fi horror films such as “Alien” and “The Thing” when it debuted, earning such comparisons for its eerie similarities.

9. ‘Pressure’ (2015)

Just off the shoreline of Somalia, seasoned divers Engel, Mitchell, Hurst, and newcomer Jones have been tasked with a risky mission: repairing a damaged underwater oil pipeline. Ignoring impending weather alerts, they set sail.

In this revised version, the sentence is made clearer by using simpler and more conversational language. The action of the divers being assigned their job is now presented as a task they have been given, and the phrase “venture out” is used instead of “they set sail,” which sounds more formal.

Despite managing to fix the pipeline, unfortunately, a violent storm sinks their vessel, claiming the lives of all aboard. Struggling against diminishing air sources, the divers desperately try to signal their survival to those above water.

Regarding Mitchell, their captain, optimism persists about a possible rescue. Yet, the pressing issue arises: will the oil firm send another ship for their rescue, or do they face the challenge of surviving on their own in the ocean’s abyss?

10. ‘Deep Blue Sea’ (1999)

A group of marine biologists and medical professionals working on a remote submarine have nearly achieved a groundbreaking discovery: a medicine extracted from shark brains, which might hold the key to curing Alzheimer’s disease.

Yet, it was unknown to the team that Susan McAlester (Saffron Burrows) and Jim Whitlock (Stellan Skarsgård), in their roles as project leaders, secretly engaged in genetic modification of sharks to expand their brains, seeking quicker outcomes for the research.

Amidst a furious tempest, while the team revels in their accomplishments, the genetically modified sharks cleverly devise an escape plan from their enclosures. Facing imminent peril, the crew – comprising of shark wrangler Carter Blake (Thomas Jane) and chef Preacher (LL Cool J) – are forced to swiftly ascend towards the water’s surface in order to stay alive.

11. ‘The Meg’ (2018)

As a film enthusiast, I’d rephrase it like this: When an enigmatic peril attacks a submerged research station run by Chinese scientists, plunging a submarine into immobility at the abyssal Mariana Trench, Dr. Zhang Suyin, the facility’s top oceanographer, reaches out to Jonas Taylor – a retired naval captain with a rich diving background.

Jonas is then thrust into a perilous mission that teeters on the brink of the impossible.

12. ‘Deep Rising’ (1998)

As I’m sailing aboard the “Argonautic” in the South China Sea, my heart races as I spot a high-speed boat filled with armed operatives, carrying an ominous cargo – a nuclear warhead.

Just off its course, the opulent ship “Argonautic” glides serenely, but suddenly falls prey to a massive, unknown beast.

Or:

In close proximity, the grand liner “Argonautic” smoothly navigates, unaware of the monstrous, mysterious creature that strikes it.

When the mercenaries step onto the ship, a few remaining individuals share stories about their terrifying experience involving massive mutated worms.

13. ‘Virus’ (1999)

In a fierce tempest at sea, Captain Everton’s (Donald Sutherland) ship, the “Sea Star,” suffered severe damage. To seek shelter, he navigates the vessel into the calm center of the storm, where the ocean is peaceful and the conditions are easier to handle.

Amidst the tranquil expanse of the sea, we chanced upon a state-of-the-art Russian vessel, eerily silent except for one lone soul aboard. Being part of the crew on the Sea Star, alongside Kelly (Jamie Lee Curtis) and Steve (William Baldwin), we ventured into this high-tech marvel. It wasn’t long before we realized we weren’t the only explorers here; we started peeling back the layers of the enigma surrounding the vanished Russian crew members.

14. ‘The Deep House’ (2021)

Ben and Tina, an enthusiastic, betrothed duo and video producers on YouTube, embark on a journey across Europe to investigate spooky homes. While roaming southwest France, they stumble upon Pierre, a local resident, who leads them to a mansion submerged in a lake.

Upon entering, they notice the house remains intact yet gives off an unsettling vibe, with bizarre occurrences such as whispers and unidentified humming noises. As they explore deeper, they stumble upon chilling images of lost kids, occult symbols, decaying bodies, and body parts. Their attempts to leave are hindered when the house’s entrances mysteriously seal off, leaving them confined within.

15. ‘The Life Aquatic with Steve Zissou’ (2004)

Famous ocean explorer Steve Zissou, portrayed by Bill Murray, is widely recognized for his captivating documentaries highlighting his worldwide underwater expeditions. However, his private life is marked by turmoil. He’s currently separated from his wife Eleanor (Anjelica Huston), maintains a strained bond with her former spouse Alistair (Jeff Goldblum), and has just learned he has an adult son, Ned Plimpton (Owen Wilson).

After the successful premiere of his newest movie, Steve sets out on a quest to track down the mysterious jaguar shark that is believed to have killed his dear friend and fellow worker.

In this journey, we have Ned, Eleanor, and renowned journalist Jane (played by Cate Blanchett) tagging along, documenting Steve’s adventures. Yet, as their expedition gets underway, the team encounters obstacles, such as run-ins with pirates.
