It was 1974, and Steven Spielberg was basically losing his mind on a boat off the coast of Martha’s Vineyard. He had this massive mechanical shark—actually three of them—named "Bruce" after his lawyer. The thing was a disaster. It sank. It exploded. Its salt-corroded skin looked like melting plastic. This legendary failure actually birthed the modern blockbuster because Spielberg had to hide the broken machine, creating the "don't show the monster" suspense that made Jaws a masterpiece. But here is the weird part: people are still obsessed with the idea of the shark still working, both the physical prop and the terrifying concept it represents.
Most movie props end up in a landfill or rot in a basement. Not Bruce. Even though the "shark still working" was a punchline for decades among the crew, the legacy of that pneumatic nightmare has evolved into a multi-million dollar preservation movement. You’ve probably seen the headlines about the last surviving shark from the original mold being restored for the Academy Museum of Motion Pictures. It’s a 1,200-pound fiberglass beast that literally spent years hanging in a sun-bleached junkyard in Sun Valley before being rescued.
The Mechanical Hell of Martha’s Vineyard
To understand why the shark still working matters, you have to realize just how much of a miracle it is that Jaws exists at all. Bob Mattey, the special effects wizard who built the giant squid in 20,000 Leagues Under the Sea, was the guy in charge. He built three versions: a "sea-sled" shark that was towed, and two "platform" sharks that moved on a massive underwater steel carriage.
They didn't test them in saltwater.
That was the fatal flaw. When they dropped the platform shark into the Atlantic, the electrolysis began immediately. The salt water ate the electrical components. The pneumatic hoses leaked. The shark would suddenly go limp or, even worse, turn into a literal killing machine that could crush a diver. Spielberg famously called it "The Great White Turd."
The production went from a planned 55 days to 159 days. The budget doubled. The producers were ready to pull the plug. But the struggle to get the shark still working is what forced the creative team to use the yellow barrels, the POV shots, and John Williams' iconic "Da-dum" score. If the shark had worked perfectly from day one, Jaws might have been just another cheesy monster movie. Instead, it became the blueprint for every thriller that followed.

Why We Can't Let Go of the Junkyard Bruce
There’s a specific shark that fans call "Junkyard Bruce." This is the fourth shark, cast from the original mold for display at Universal Studios. It sat at the park for years, then was sold to a guy named Sam Adlen who owned a wrecking yard. For 25 years, it just hung there, baking in the California sun.
In 2016, it was donated to the Academy Museum. This is where the story of the shark still working takes a turn into high-end art restoration.
Roy Arbogast, who was on the original SFX crew, helped guide the restoration. They didn't just slap some paint on it. They had to strip decades of grime, reinforce the internal structure, and recreate the teeth and eyes to match the 1975 screen version exactly. Seeing that shark today, hanging over the escalators in a pristine museum, feels surreal. It’s a testament to the fact that we value the physical struggle of filmmaking in an era where everything is just CGI and green screens. There is a weight to it. A presence. You can almost feel the frustration of those 1974 crew members radiating off its fiberglass skin.
The Psychology of the Mechanical Monster
Why do we care if the shark is still working? Honestly, it's about the tangible. CGI sharks in movies like The Meg look "perfect," but they don't feel real. We know, on a primal level, that there's nothing actually displacing the water.
- Tactile Fear: When you see the mechanical Bruce lunge at the boat, you're seeing actual physics.
- Historical Weight: It represents the era of "suicide filmmaking" where directors risked their entire careers on a hunk of metal.
- Nostalgia: For many, the shark is the definitive movie monster, more "real" than Godzilla or King Kong because sharks actually exist.
The Modern "Working" Shark: Robotics Today
If you go to a theme park today, you'll see animatronics that would make 1974 Spielberg weep with envy. Modern hydraulic systems and silicon skins mean a shark still working today doesn't just bite—it breathes, its eyes track movement, and its skin ripples.

Walt Disney Imagineering and companies like Garner Holt Productions have pushed this tech to the limit. We’re talking about robots that can perform the same movement millions of times without a single hose bursting. But there's a trade-off. There is something incredibly charming about the clunky, jerky movement of the original Bruce. It had a personality born of its malfunctions.
In the world of professional creature effects, "working" is a relative term. A puppet is only "working" if the audience believes it’s alive. The original shark failed as a machine but succeeded as a character. That is the ultimate irony of the whole production.
Behind the Scenes: The Men Who Fought the Fish
Joe Alves, the production designer, deserves way more credit than he gets. He was the one who actually scouted the locations and designed the look of the shark. He knew the water would be a nightmare. He warned people.
Then you had the divers. These guys were underwater in murky, freezing water, trying to untangle lines while a multi-ton steel platform moved blindly around them. It was incredibly dangerous. When people talk about the shark still working, they are really talking about the labor of the hundreds of technicians who refused to let the ocean win.
Common Misconceptions About the Jaws Shark
- "They only had one shark." Nope. They had three main ones and the fourth display casting.
- "It was a complete robot." Not really. It was more of a giant puppet controlled by a massive underwater crane system.
- "Spielberg hated the shark." He hated the malfunction, but he loved the idea. He’s since become a huge supporter of the restoration efforts.
How to Experience the Legacy Today
If you want to see the shark still working—at least in its final, preserved form—you have to go to Los Angeles. The Academy Museum of Motion Pictures is the only place you can stand under a full-scale Bruce. It’s an intimidating experience. Even though you know it’s just fiberglass and steel, your lizard brain tells you to move away from the teeth.

Beyond the museum, the legacy lives on in the "Jaws" ride at Universal Studios Japan. While the Orlando and Hollywood versions of the ride have been closed or changed significantly, the Japan version still features a massive, working mechanical shark that attacks the boat. It’s the closest you can get to being on the Orca without actually heading out to sea.
Actionable Steps for Jaws Fans and Film History Nerds
If you’re obsessed with the technical side of how these monsters were brought to life, you don't have to just watch the movie for the 50th time. There are ways to dig deeper into the "shark still working" lore.
Visit the Academy Museum in Los Angeles. Seeing the 25-foot "Junkyard Bruce" in person is a bucket-list item. Look closely at the eyes—they were recreated to have that specific, dead-eye stare that Quint describes in his famous Indianapolis speech.
Read "The Jaws Log" by Carl Gottlieb. Gottlieb was the screenwriter who was on set during the whole chaotic mess. It’s the best first-hand account of the mechanical failures and the "shark still working" saga. It’s essentially a diary of a production falling apart and being saved by sheer willpower.
Study the "Jaws" Restoration Documentary. There are incredible featurettes on the Blu-ray and 4K releases that show the actual mechanics. Pay attention to the "pneumatic" vs "hydraulic" debate. Understanding how they moved those tons of steel under the surface will change how you view the movie.
Follow Greg Nicotero’s work. The legendary SFX artist (of The Walking Dead fame) was a huge part of the community that helped track down and validate the surviving shark pieces. His social media often features deep dives into classic practical effects.
The shark still working isn't just a piece of trivia. It's a reminder that in creative work, the things that go wrong are often the things that make the final product legendary. The broken shark forced a better movie. The decaying prop forced a better museum. Sometimes, the struggle is the point.
