“If they pay me and if they do what I say, I’ll never bother them again.” — Young Man

James Goldstone’s 1977 film Rollercoaster exists in a fascinating, albeit deeply flawed, space within the history of seventies disaster cinema. If you are a fan of retro 70s movies, specifically the whole Sensurround era where Hollywood was desperately trying to get people out of their living rooms and into theaters with seat-rumbling audio gimmicks, you have probably heard of this one. It has a genuinely neat, gritty vibe because it was actually shot on location at real amusement parks like Kings Island and Magic Mountain. You get this awesome, vintage, mid-century theme park atmosphere that you just cannot fake on a studio backlot. You can almost smell the cotton candy, the hot asphalt, and the stale beer. But once that initial wave of nostalgia wears off, you are left looking at what is actually on the screen, and honestly, Rollercoaster is not a great film. In fact, one could very easily say it is not even a good film. At its absolute best of times, it is a thoroughly average, middle-of-the-road thriller that feels more like a slightly elevated, padded-out television movie of the week than a major theatrical release.

The plot is about as standard as it gets for this era of disaster-adjacent cinema. A mysterious, young terrorist starts blowing up rollercoasters, not for any grand political manifesto, but simply to extort amusement park owners for millions of dollars. Enter our protagonist, Harry Calder, played by George Segal, who is a cynical safety inspector that just happens to survive the first derailment. Segal is basically just playing George Segal here—exasperated, a bit snarky, wearing a rumpled suit, and teaming up with an FBI agent played by Richard Widmark. The villain is played by a very young Timothy Bottoms, who is effectively creepy but given virtually zero backstory or motivation. He is just a blank-eyed psycho doing psycho things because the script needs an antagonist. The movie essentially just bounces from one park to another, with Segal walking around looking stressed while the FBI tries to figure out where the next bomb is hidden.

The pacing is arguably the film’s biggest sin. For a movie literally named Rollercoaster, it is shockingly lacking in momentum. Goldstone’s direction completely lacks the tight, pulse-pounding beats you would expect from a high-stakes thriller. There is so much filler here, so many scenes of Segal drinking coffee and staring at blueprints, and so much tedious FBI bureaucratic nonsense that it completely kills any tension. The romantic subplot feels entirely tacked on, and the climax fails to deliver the massive, explosive payoff you have been waiting for. If you judge Rollercoaster purely on its cinematic merits—the acting, the script, the direction—it is undeniably average, the kind of movie you leave on in the background while you fold laundry.

However, despite all of these glaring, undeniable flaws, Rollercoaster has a fascinating, almost prophetic legacy when you look back at the history of the thriller genre. It may not be remembered as a great movie, but it essentially built the exact template for an entire subgenre of cat-and-mouse thrillers that dominated the 90s. It practically invented the “specific-professional-against-a-psychopathic-mastermind” formula. Before Rollercoaster, thrillers were usually about spies, cops, or generic everymen. But this film introduced the idea of a highly specific, niche expert being forced into a one-on-one intellectual duel with a terrorist who targets them specifically because of their expertise. Think about how that exact template was endlessly copied and refined in the decades that followed. Look at In the Line of Fire, where Clint Eastwood plays a Secret Service agent hunted by a psycho played by John Malkovich. Or look at Blown Away, where Jeff Bridges is a bomb-defusing expert tormented by an Irish terrorist played by Tommy Lee Jones. Even The Bone Collector fits this mold perfectly, with Denzel Washington’s bedridden forensics expert being targeted by a serial killer who uses specific crime scenes just to test Washington’s intellect. All of these films drew direct DNA from Rollercoaster, using that exact same dynamic of a reluctant protagonist with a very particular set of skills being singled out by a psychopath who treats mass murder like a twisted, personalized game of chess. And if you want the absolute pinnacle of the “expert vs. bomb” trope, you have to look at Speed, which polished the cat-and-mouse dynamic perfected right here in Rollercoaster.

Because the original film was so hampered by 1970s filmmaking technology, it really makes you realize how easily this movie could be remade in this day and age. Back then, the actual destruction of the rides was limited by practical effects, clunky models, and standard camera angles that made the crashes feel somewhat static and safe. Today, technology in filmmaking has advanced to the point that the sheer scale, speed, and physical danger of the rides themselves really does become the focus of real danger. With modern CGI, drone cameras, and advanced practical rigging, you could put the audience right inside the front car of a 300-foot hyper-coaster as the tracks buckle and twist in slow motion. You could make the metal fatigue, the snapping cables, and the horrific physics of a derailment feel genuinely terrifying, turning the amusement park rides into massive, mechanical monsters rather than just static backdrop props for guys in suits to talk around.

Naturally, if Hollywood were to actually remake Rollercoaster today, you know exactly how it would look and who would star in it. It would undoubtedly star someone like Dwayne Johnson or Chris Pratt, a guy who can deliver a quip while looking concerned and holding a blueprint. They would inevitably give the safety inspector a tragic backstory, probably a dead wife or a kid they are estranged from, just to artificially raise the emotional stakes. And because it is a high-concept thriller that does not quite have the cultural weight of a massive comic book franchise, the remake would almost certainly be relegated to a streaming release. It would drop on a Friday on Netflix or Amazon Prime with a generic, algorithmically tested poster and a slick, forgettable title. It would be exactly the kind of mid-budget, mildly entertaining action flick you watch on a rainy Sunday afternoon before completely forgetting about it by Monday morning.

So, ultimately, how do you rate a movie like Rollercoaster? You just have to accept its extreme averageness and respect its ripple effect. It is clunky, the performances are uneven, and it is rarely as thrilling as its title promises. But it absolutely should not be written off entirely. It was the exact moment Hollywood realized that pitting highly specialized professionals against high-concept villains made for compelling, relatable drama. Without George Segal boredly walking around Magic Mountain, we probably do not get the overly dramatic, incredibly ridiculous, yet thoroughly entertaining 90s thriller boom, nor the slick, CGI-heavy streaming thrillers of today. Rollercoaster might just be a mediocre hill, but it is undeniably the hill that started the entire ride.
