Peter Ustinov had this way of wearing a three-piece suit that made him look like an upholstered armchair. It was perfect. When people talk about the dead man's folly movie, they’re usually either reminiscing about the sun-drenched 1986 television film or they’re confused by the more recent, darker David Suchet version. There’s a massive difference.
Agatha Christie's 1956 novel is a weird one, honestly. It’s set at Greenway, her own actual estate in Devon, which gives the whole thing this bizarrely intimate, almost voyeuristic vibe. If you’ve seen the 1986 film, you’ve basically walked through Christie’s front door. They filmed it right there. It’s the only time that happened during that era of Christie adaptations.
The Peter Ustinov Factor and the 1980s Aesthetic
Look, Ustinov wasn’t Christie’s Poirot. Not really. The "real" Poirot of the books was a tiny, fastidious man who would have been horrified by Ustinov’s sprawling, rumpled presence. But in the dead man's folly movie, Ustinov brings a warmth that makes the mystery actually enjoyable rather than just a cold logic puzzle.
He’s joined by Jean Stapleton. Yes, Edith Bunker herself. She plays Ariadne Oliver, the eccentric mystery novelist who is clearly Christie’s self-parody. Their chemistry is basically the reason to watch this version. It’s light. It’s airy. It feels like a summer holiday where someone happens to get strangled.
The plot is famously convoluted. Mrs. Oliver is asked to stage a "Murder Hunt" (a 1950s version of a murder mystery party) for a local fete at Nasse House. But she gets a "hunch"—and in Christie-land, Ariadne’s hunches are basically psychic premonitions—that something is wrong. She calls in Poirot. Then, the girl playing the dead body ends up actually dead.
It’s a classic setup.
Location, Location, Location: The Greenway Magic
Most movies use sets. They use clever angles. This dead man's folly movie used the real deal. Greenway, the house used in the film, was Christie's "dream house." The boathouse where the murder occurs? That’s her boathouse. The narrow woodland paths where the suspects wander? Those are the paths she walked while brainstorming how to kill people off on paper.

There is a specific shot in the 1986 film where the camera pans across the river Dart. It’s stunning. It captures a version of England that was already disappearing when the book was written. By the time the movie was filmed in the mid-80s, that "Old England" feel was pure nostalgia.
Comparing the Versions: Suchet vs. Ustinov
You can't talk about the dead man's folly movie without mentioning the 2013 adaptation starring David Suchet. It was part of the final season of Agatha Christie's Poirot.
The vibe shift is jarring.
- The 1986 version: Sunny, slightly campy, feels like a Sunday afternoon tea.
- The 2013 version: Melancholic, grey-toned, emphasizes the tragedy of the ending.
- The 1986 version: Features a very young Nicolette Sheridan.
- The 2013 version: Features a much more faithful, "obsessive-compulsive" Poirot.
Honestly? Most fans are split. If you want the grit and the psychological depth, Suchet wins. But if you want to see a movie that feels like the experience of reading a Christie novel on a beach, the Ustinov film is the one. It doesn't take itself too seriously. It knows it's a "whodunnit" and leans into the theatricality of it all.
Why the Mystery Actually Works
A lot of Christie's plots rely on "the double bluff." Without spoiling the ending for the three people who haven't seen it, Dead Man's Folly hinges on the idea of identity and architectural secrets. The "Folly" in the title refers to a small, decorative building on the grounds. In real-life estate planning, a folly is a building with no purpose.
In this movie, the folly is the center of the universe.

The supporting cast in the '86 film is a "who’s who" of "hey, I know that guy" actors. You have Tim Pigott-Smith, who was a staple of British drama, and Constance Cummings. They play the owners of Nasse House, the Legges. They represent that post-war upper class that is desperately trying to hold onto their estates while the world changes around them.
The "Discovery" Value: Why You Should Watch It Now
We are in a bit of a Christie renaissance right now with the Kenneth Branagh films. But those movies are CGI-heavy spectacles. Watching the dead man's folly movie from 1986 is a palate cleanser. It’s tactile. You can practically smell the damp grass and the old wood of the boathouse.
It’s also a masterclass in 1980s costume design trying to look like the 1950s. It’s not always historically accurate, but it’s stylish.
One thing most people miss: the film addresses the weirdness of tourism. The "Murder Hunt" is essentially a way to bring people into the estate to make money. It’s meta. Christie was writing about the commodification of her own genre before it was even a thing.
Factual Details You Might Have Missed
The production of the 1986 film was actually a big deal for Warner Bros. Television. They didn't just film in Devon; they filmed at various locations around London to get the "Poirot at home" feel.
Interestingly, the script was handled by Rod Browning. He had to condense a fairly long, talky novel into a 90-minute TV movie format. He kept the "Marlene Tucker" character—the victim—mostly as she was in the book: a girl who knew too much and was too bored for her own good.

The motive in the movie is often criticized for being "too complex," but that’s Christie for you. It’s not just about money; it’s about the lengths people go to to erase their past.
How to Watch and What to Look For
If you’re looking to track down the dead man's folly movie, it’s often bundled in "Poirot Movie Collections."
Pay attention to the scene at the fete. The extras weren't just random actors; many were locals from the Galmpton area near Greenway. It gives the fair scenes a genuine, chaotic energy that you don't get with professional background artists.
Also, watch Ariadne Oliver’s hats. They get increasingly ridiculous as the movie progresses. It’s a subtle nod to her fraying nerves as her "fun" murder game turns into a literal crime scene.
Actionable Steps for Christie Fans
To get the most out of this specific piece of cinema history, don't just watch it as a standalone film.
- Watch the 1986 version first to get the geography of Greenway into your head. It’s the best "tour" of the house you can get without buying a plane ticket to England.
- Read the book afterwards. You’ll notice how much the movie simplified the "Hattie Stubbs" character. The book goes much deeper into her mental state—or lack thereof.
- Visit the National Trust website for Greenway. They have photos of the house as it looks today. You can see the actual spots where Ustinov stood.
- Compare the endings. The 1986 movie plays the reveal with a bit of a flourish, whereas the 2013 version treats it like a funeral. See which one fits your mood.
The dead man's folly movie remains a staple of the mystery genre because it captures the essence of the "Cozy Mystery" before that term became a marketing cliché. It’s a snapshot of a specific time in filmmaking and a specific place in literary history. It's not perfect—Ustinov’s accent wanders somewhere between Brussels and Brooklyn—but it’s undeniably charming.
If you want a mystery that feels like a vacation with a slightly eccentric uncle, this is the one to put on your watchlist. It's a reminder that sometimes the best way to solve a murder is with a bit of panache and a very large hat.
