You’re sitting on your couch, scrolling through Netflix or Max, and it feels like every third thumbnail is a wave, a shark fin, or a submarine. It makes you wonder: how many ocean movies are there, really? Is it hundreds? Thousands? Does the industry just have a thing for the color blue?
The short answer is: nobody knows for sure. That sounds like a cop-out, but stay with me. If you check the Internet Movie Database (IMDb), you’ll find thousands of titles tagged with "ocean," "sea," or "underwater." But that includes everything from 1920s silent shorts to that weird low-budget shark movie your cousin made in Florida. Honestly, the number is staggering because the sea is one of the oldest storytelling devices we have. It’s a setting, a character, and a monster all at once.
The Impossible Math of How Many Ocean Movies Are There
Pinning down an exact figure for how many ocean movies are there is like trying to count the grains of sand on a beach while the tide is coming in. If we’re talking about "major" feature films—the ones that actually hit theaters or big streaming platforms—we’re likely looking at a number north of 2,500.
Why is it so hard to count?
Definition matters. If a movie has one scene on a boat, does it count? Probably not. But what about Titanic? Most of that movie happens on a ship, not in the water, yet we all categorize it as a quintessential ocean flick. Then you’ve got the sub-genres. You have documentaries like My Octopus Teacher, horror hits like Jaws, and animated classics like Finding Nemo.
According to data aggregators like Letterboxd and IMDb, if you filter for the "Ocean" or "Sea" keyword, you get a list that stretches on forever. IMDb lists over 5,000 titles tagged with "Ocean." But let's be real—a lot of those are episodes of TV shows or obscure documentaries. When people ask about the volume of these films, they’re usually thinking of the big hitters. The blockbusters. The stuff that makes us afraid to go into the water.
Why We Can't Stop Filming the Deep
Humans have a weird relationship with the water. We need it to live, but it’s also a terrifying void where we can't breathe. That tension is pure gold for directors.
Think about the sheer variety. You’ve got the "Man vs. Nature" stories. The Old Man and the Sea (1958) or All Is Lost (2013) with Robert Redford. These movies use the ocean as a mirror for the human soul. It's lonely. It’s quiet. It's brutal.

Then you have the "Creature Features." This is where the numbers really start to climb. Since Steven Spielberg changed the world with Jaws in 1975, the "killer shark" genre has basically become its own economy. There are over 50 Sharknado-style B-movies released almost every decade now. It’s a literal flood of content.
And don’t forget the technical masterpieces. James Cameron is basically the king of this. He didn't just make Titanic and The Abyss; he went and made Avatar: The Way of Water, which pushed digital ocean physics to a level we’ve never seen. He’s obsessed. And because he’s obsessed, we get more movies.
Breaking Down the Sub-Genres
To understand the scale of how many ocean movies are there, you have to look at the buckets they fall into. It’s not just one big pile of blue.
The Survival Epic
These are the heavy hitters. Cast Away (though mostly on an island, the ocean is the antagonist), Life of Pi, and In the Heart of the Sea. These films often cost a fortune because filming on water is, quite frankly, a nightmare. Ask Kevin Costner about Waterworld. That movie almost broke him and the studio because the ocean doesn't care about your filming schedule. It moves your sets, it rusts your equipment, and it makes your actors seasick.
Animated Adventures
This is a massive slice of the pie. Moana, The Little Mermaid (both versions), Shark Tale, and Luca. Animation allows us to see the ocean in a way live-action can't—vibrant, bioluminescent, and full of talking crabs. Disney and Pixar alone account for dozens of the most profitable ocean-themed films in history.
The Submarine Thriller
There’s a specific claustrophobia here. The Hunt for Red October, Crimson Tide, U-571, and the legendary Das Boot. These movies are "ocean movies" by proxy. You don't see the water as much as you feel the pressure of it. It’s a sub-genre that has stayed consistent since the 1950s.
The Reality of "Keyword" Bloat
If you’re looking for a definitive list, you’re going to run into "keyword bloat." On sites like Rotten Tomatoes or MUBI, tagging is a bit of a mess. A movie like Moonlight might be tagged with "ocean" because of one pivotal scene at the beach. Does that make it an ocean movie? Not really.

If we filter for films where the ocean is the primary setting or plot driver, the number becomes more manageable but still stays in the low thousands.
- 1900-1950: Mostly adventure serials and early adaptations of 20,000 Leagues Under the Sea.
- 1950-1980: The rise of the "Sea Monster" and the birth of the modern blockbuster.
- 1980-Present: High-tech CGI underwater worlds and an explosion of low-budget VOD shark movies.
It’s also worth noting that international cinema contributes heavily. Japan has a deep history of maritime films, often focused on fishing villages or Godzilla-style threats emerging from the trench. French cinema, thanks to legends like Jacques Cousteau, basically invented the modern underwater documentary. When you add up global output, the count of how many ocean movies are there rises significantly.
The High Cost of the Blue Screen
One reason there aren't even more ocean movies is the cost. Water is the most difficult element to simulate and work with.
James Cameron’s The Abyss was filmed in an unfinished nuclear power plant tank. The actors were miserable. The crew was miserable. The budget spiraled. This "curse of the water movie" is a real thing in Hollywood. It keeps the number of high-quality ocean films lower than, say, the number of "city-based rom-coms." You can film a rom-com in Central Park for a fraction of what it costs to get a camera crew three miles offshore.
Despite the hassle, the allure remains. There’s something about the horizon line that calls to filmmakers. It represents the unknown.
How to Find Your Next Deep-Sea Watch
If you’re trying to navigate this massive library, don't just search for "ocean movies." You’ll get a mess of results. Instead, categorize your search by "vibe."
If you want realism, look for "Maritime History" films. These are based on true stories, like The Finest Hours or Master and Commander: The Far Side of the World. These movies respect the ocean’s power.

If you want to turn your brain off, look for "Creature Features." Honestly, some of the best fun you can have is watching a low-budget movie where a prehistoric megalodon fights a giant octopus. It's a staple of the genre.
For the visual learners, the "Natural History Documentaries" are where the real beauty lies. Blue Planet isn't a movie, but its cinematic quality puts most Hollywood films to shame. The footage captured by the BBC Natural History Unit has defined how we visualize the deep for twenty years.
The Future of the Genre
We are currently seeing a massive uptick in ocean-related content. Why? Technology is finally catching up to the vision.
With underwater performance capture—the tech used in Avatar—we can finally see actors "swim" in a way that looks real. We’re no longer stuck with people dangling on wires in front of a blue screen while a fan blows their hair. This means the question of how many ocean movies are there is going to have a much larger answer in ten years.
Streaming services are also hungry for "high-concept" survival stories. A movie like The Shallows or Crawl (which is technically a hurricane/flood movie, but close enough) proves that you can make a lot of money with one actor and a lot of water.
Actionable Steps for Ocean Film Fans
If you're looking to dive into this massive collection, don't just swim aimlessly. Start with a curated approach to the thousands of titles available.
- Check the Classics First: You cannot understand the genre without seeing Jaws (1975) and 20,000 Leagues Under the Sea (1954). They set the blueprint for everything that followed.
- Use Specific Database Filters: On IMDb, go to the "Advanced Title Search." Instead of just searching "ocean," use the "Plot" filter for "trapped at sea" or "underwater base." This clears out the junk and gets you to the meat of the genre.
- Explore International Titles: Look into Das Boot (Germany) or Ponyo (Japan). The ocean looks different through different cultural lenses, and some of the best cinematography isn't coming out of California.
- Track the New Releases: Keep an eye on the "Aquatic Horror" tags on streaming platforms. It’s one of the fastest-growing niches because it's cheap to produce and people love a good scare.
The ocean is the last great frontier on Earth. It makes sense that we keep making movies about it. Whether it’s a terrifying shark or a beautiful coral reef, we’re drawn to it. The number of movies might be impossible to count exactly, but the quality of the best ones is what keeps us coming back.
Start by picking a sub-genre that fits your mood. Do you want to be inspired, or do you want to be too scared to take a bath tonight? There are thousands of options waiting for you. Just grab a life vest and start watching.
