Film
Westworld
Before Skynet, before Jurassic Park, there was this: Michael Crichton's own theme-park nightmare, where rich guests pay to gunfight, joust, and bed lifelike androids that are guaranteed to lose. Yul Brynner's black-clad gunslinger is the whole show — an expressionless, tireless killing machine years before that idea had a name. Slim, occasionally creaky, but genuinely unnerving once it gets its hooks in.

The same premise stretched into six seasons of prestige sprawl — if you want the park's implications chewed over at length, with consciousness, timelines, and a much bigger body count.
But It gets increasingly baroque and mythology-obsessed; the clean B-movie thrill of the original curdles into puzzle-box television by season two.

The Terminator1984
Brynner's blank, unstoppable gunslinger is the direct ancestor of Schwarzenegger's killing machine — this is the film that shows you exactly where that particular nightmare was born.
But Different genre entirely, a full-throttle chase thriller with a human hero rather than a theme-park satire, so the family resemblance only runs so deep.

Jurassic Park1993
Same author, same engine: a rich man's amusement park promising total control over dangerous technology, and the gleeful collapse of that promise once things start working a little too well.
But It's a family-friendly blockbuster at its core, dinosaurs instead of androids, with none of Westworld's uneasy adult undertone.

The wildcard
Something you would not have found on your own.
Duel1971
Two years apart, Crichton and Spielberg were chasing the same fear from opposite directions: a faceless, mechanical pursuer with no motive and no mercy, hunting an ordinary man who can't understand why it won't stop. Same nightmare, wildly different costume — Western theme park versus empty American highway.
Ninety minutes of pure, minimal dread: an ordinary commuter is stalked across empty highways by a truck whose driver you never see, and the film never once explains why.
But There's barely a plot beyond the chase and long stretches with almost no dialogue — the ambiguity that makes it eerie will frustrate anyone wanting answers.
