Duel (1971) – Review

Before Jaws, before Jurassic Park, before Spielberg was the patron saint of summer blockbusters, he made a film that proved you don’t need a giant shark or prehistoric monsters to terrify an audience, all you need is a faceless truck, a stretch of desert highway, and the nerve to keep the camera rolling as it bears down on you like an angry mechanical dinosaur.

Based on a Richard Matheson short story, Duel is, at its core, a simple premise dressed in pure tension. David Mann (Dennis Weaver) is your average salesman, average car, average suit, average sense of direction. Driving through the California desert on a work trip, he makes the fatal mistake of overtaking a grimy Peterbilt truck. This isn’t a “sorry buddy, didn’t mean to cut you off” kind of situation. This truck—anonymous, rusted, and probably smelling like hot oil and regret—takes it personally. What follows is essentially a 90-minute game of vehicular cat-and-mouse, with Mann as the mouse, and the cat being a several-ton road leviathan intent on turning him into roadkill paste.

When relentless meets nail-biting. 

And then there’s the ending, pure, primal satisfaction, the kind that bypasses cleverness and goes straight to the gut. It’s just a man, a machine, and the inevitability of one giving way to the other. The scene unfolds with a grim, almost ritualistic clarity. Mann doesn’t triumph so much as he survives. The truck, once this hulking, relentless predator, lurches forward into its death throes, its roars and groans echoing in the empty desert like some wounded prehistoric beast. When it finally tips into the abyss, the moment doesn’t erupt into a cheer; it settles into a long, cathartic exhale, the way your lungs ache after holding your breath for 90 minutes. It’s victory by attrition, a release earned through endurance, not bravado.

David Mann, battered but unbeaten.

Stray Observations:

• The truck’s front bumper is decorated with various out-of-state license plates, implying this isn’t the first time it’s hunted down motorists. Those aren’t random; they were added as a sly nod to a serial killer’s trophy wall.
• David Mann goes out of his way twice to obtain change to call 0 for the Operator to make collect calls on payphones. Calling 0 for the Operator is a free call, no payment required, the same for calling 911.
• In real life, Mann’s Plymouth Valiant could have left that Peterbilt in the dust with one good stomp on the gas. But Duel isn’t about realism; it’s about sustained tension, so the movie bends plausibility to keep the predator-prey dynamic alive.
• An episode of The Incredible Hulk series, “Never Give a Trucker an Even Break,” used a large percentage of footage from Duel.
• Spielberg, at this point, hadn’t yet teamed up with composer John Williams, but Billy Goldenberg creates a tense and suspenseful atmosphere throughout the film with his score. Solid work.
• When the truck finally goes off the cliff, Spielberg reused a stock sound effect of a dinosaur’s death from 1957’s The Land Unknown. The same sound later popped up in Jaws when the shark dies.

A primal roar that echoes like a prehistoric beast’s last scream.

Spielberg, barely 25 at the time, directs with the kind of confidence you’d expect from someone who’s been making thrillers for decades. His use of camera placement turns stretches of open road into corridors of dread. The truck’s driver is never shown, making the vehicle itself the antagonist. It’s not just a truck, it’s a predator, snorting black exhaust like a dragon’s breath and lumbering forward with a patience that’s somehow scarier than full-on speed. This anonymity elevates the story from a road rage tale into a parable about faceless danger, about the terror of the unknown bearing down on you.

The anonymity of evil.

Dennis Weaver sells every moment. His gradual slide from mild irritation to full-blown panic is a masterclass in sweaty-palmed paranoia. There’s a diner scene where he tries to guess which patron is the truck driver—one of Spielberg’s first truly Hitchcockian moments—that’s so tense you almost hear Psycho violins. And while it’s “just” a TV movie, Spielberg’s direction makes it cinematic: low camera angles that make the Peterbilt look like Godzilla on wheels, tight shots that trap you in the Plymouth Valiant with Weaver, and editing that keeps the action relentless.

His name is David Mann — as in “everyman.” Subtle, Spielberg.

What’s fascinating is how Duel still works today because road rage hasn’t gone anywhere; it’s just gotten Bluetooth and bad playlists. This film taps into a primal fear: the idea that you’ve crossed paths with someone who won’t let it go, someone who decides you are their mission. The only “special effect” here is the truck itself, and it’s more terrifying than most CGI monsters. By the end, Mann is pushed to the edge (literally) in a showdown that feels less like man vs. machine and more like prey finally standing up to a predator. It’s cathartic, but also leaves you wondering, what if there’s another one out there?

And what if it’s already behind you on the highway?

In conclusion, Duel remains one of Spielberg’s leanest and meanest works, a masterclass in pacing and visual storytelling that wrings relentless suspense out of the everyday. With razor-sharp economy, it transforms a simple highway chase into a psychological battle, turning an anonymous semi-truck into a relentless, almost malevolent force that stalks its prey with mechanical precision. The film taps into a deep, primal fear of losing control to something unstoppable and unseen, making viewers question the safety of the ordinary. After watching Duel, you’ll never look at a passing semi the same way again, wondering if it remembers that one time you merged a little too close, or hesitated just long enough to earn its silent, terrifying revenge.
