PIRANHA Original Trailer + TV Spot (1978) Joe Dante

When Joe Dante’s Piranha swam onto screens in 1978, it did so under the long shadow of that other great “fish movie” Jaws. But rather than sinking as a cheap imitation, it found its own viciously funny groove. Directed by Dante and written by future Oscar-nominee John Sayles, Piranha is a fast-paced, blood-splattered blend of horror, satire, and schlock. It follows a school of genetically engineered piranha unleashed into a river system, just as a nearby summer resort fills with unsuspecting tourists.

With its modest Roger Corman budget, the film makes the most of limited special effects, relying on blood-red waters and reaction shots rather than fully visible monsters. What it lacks in visual polish it more than makes up for in wit and a gleeful homage to the genre.

More than four decades on, Piranha endures as a cult classic thanks to its subversive intelligence and unmistakable affection for the monster movie. Sayles’s script skewers military irresponsibility and corporate greed (the piranha were designed for use in Vietnam, and pollution becomes a plot device), while Dante infuses every frame with energy and affection for his cast of quirky character actors.

Boasting cult icons like Dick Miller and Barbara Steele, the scenery is enthusiastically chewed as the titular fish feast on unsuspecting swimmers’ limbs. Between the creative kills and cynical one-liners, Piranha is as much a celebration of low-budget filmmaking as it is a creature feature. Clearly an influence on filmmakers like Jon Turteltaub who made the giant-shark movie The Meg, and other schlocky monster flicks about killer animals like Lewis Teague’s Alligator and Steve Miner’s Lake Placid, Dante’s 1978 effort, which also led to a sequel and two remakes, has rightly earned its place in the horror hall of fame.

Big Fish: A Sub-Genre Swimming With Cult Favorites

Fish-themed horror movies have delivered everything from psychological terror to full-throttle monster madness over the years. Jaws stands out as the Granddaddy of the genre, but others like Piranha have joined it to bring the thrills of the rivers and the seas to the big screen.

Indeed, fish have become an increasingly common sight. In horror, 1999’s Deep Blue Sea gave us genetically enhanced sharks in a submerged lab, while 2003’s Open Water stripped things down to bare-bones realism, offering a harrowing depiction of isolation and dread. It’s not just in horror though, the theme has also been explored in films championing fishing as both sport and hobby, from the absorbing drama of 1992’s A River Runs Through It to the tender delights of 2011’s Salmon Fishing in The Yemen.

Interestingly, the activity has become more and more present in pop culture and entertainment in everything from video games like Red Dead Redemption 2 to TV shows like Deadliest Catch. Casino games like the hugely popular angling-based Big Bass series of slots are similarly topping the iGaming charts. Big Bass Bonanza and Big Bass Splash are two of the most well-known titles and, for example, a prominent part of top platforms like Buzz Bingo’s promotional offers for new customers, such as their slots welcome bonus to play Bonanza and Splash with 200 free spins.

Piranha Continues to Send Ripples Through Movies and Beyond

Almost 50 years after its release, Piranha endures not just as a Jaws-era knock-off, but as a razor-sharp satire wrapped in monster movie mayhem. Its clever script, DIY effects, and anarchic tone struck a nerve with horror fans, and continue to inspire homages and fish-themed terrors across film. Piranha didn’t just bite; it left a lasting mark.
