These Terrifying Movies Will Ruin Your Beach Vacation

The Little Mermaid would have you believe the ocean floor is a nonstop party, where crabs sing and fish play the clarinet. Unfortunately, nature's not as friendly in real life. The film 47 Meters Down, out this Friday, will do a good job of shattering any lingering childhood illusions of vegetarian sharks or musical crustaceans.
The movie starts, as so many aquatic-themed horror movies do, with a "fun activity." Two sisters, Lisa (Mandy Moore) and Kate (Claire Holt), buckle into their shark tank for a scuba diving adventure. Plot twist: The tank detaches from the boat and floats to the bottom of the ocean, where the sisters contend with circling sharks and a dwindling oxygen supply.
The summer flick is merely the latest in a long line of works that prey on our fear of the deep blue sea. Before 47 Meters Down, there was Jaws. And before there was Jaws, there was Moby-Dick, the classic novel about a war between whale and man. Each of these movies captures the terror of being lost at sea.
Enjoy your cruise this summer, by the way.

Jaws (1975)

Jaws is a classic thriller movie about a group of Cape Coders who face off against a great white terrorizing their community. Or maybe, just maybe, Jaws is a metaphor for the forces of destruction that can arise just when we think waters are calm. However you read Jaws, you'll stay close to the shore after watching it.

The Life Of Pi (2012)

Most films take the terror of being stranded at sea, and create bloody, suspenseful thrillers involving sharks and piranhas. But only Life of Pi takes that primal fear and weaves a visually-stunning fantasy about a boy trapped on a lifeboat with a tiger. Life of Pi is powerful whether you choose to interpret its fantastical events as truth, or a metaphor for survival.

The Reef (2010)

When their ship capsizes on the way to Indonesia, the passengers decide to swim to a nearby island. But, as all open-water movies prove, where young swimmers are, sharks can't be far behind. Like Open Water, this harrowing film is based on the true story of Ray Boundy, who was stranded in a similar way.

Unsurprisingly, both The Reef and Open Water hurt the Great Barrier Reef tourism industry.

Lifeboat (1944)

This suspenseful Alfred Hitchcock thriller catches a group of Americans and Brits who take refuge on a lifeboat after their ship is hit by a German U-Boat missile.

Sharknado (2013)

What, you didn't think this movie about a tornado that unleashes great white sharks onto unsuspecting land mammals would make the cut? You thought wrong.

The Shallows (2016)

If you're considering a solitary retreat, perhaps consider a spa — not a secluded beach. Nancy Adams (Blake Lively) chooses the latter, and is attacked by a great white while surfing. She seeks refuge on a tiny rock 200 yards from shore. What follows is a taut, intelligent battle for survival. It's a shark-eat-human world out there, folks.
