Patrick Bateman is a monster. We know this from the first frame of Mary Harron’s 2000 masterpiece, but nothing cements his status as a cinematic icon of chaos quite like the American Psycho chainsaw scene. It’s loud. It’s messy. It is, quite frankly, one of the most absurd sequences in horror history. If you’ve seen it, you can probably still hear the roar of the engine echoing through that sterile, white hallway.
Christian Bale didn't just play a serial killer; he played a man performing the role of a human being. When he chases Christie—a character who is essentially a lamb to the slaughter—through the corridors of his luxury apartment building while wearing nothing but a translucent raincoat and sneakers, the movie pivots. It stops being a satire of Wall Street and becomes a slasher film that’s also somehow a dark comedy. It’s a tightrope walk.
People always ask if that scene was actually in Bret Easton Ellis’s book. The short answer? Yes, but it’s way worse on the page. Harron had to find a way to make the carnage palatable for a theatrical audience while still retaining the "yuppie nightmare" energy that makes the story work. She succeeded.
The Logistics of Running with a Power Tool
Think about the physical reality of filming the American Psycho chainsaw scene. Christian Bale is sprinting. He’s naked, save for those sneakers and the coat. He’s carrying a heavy, vibrating piece of machinery. One slip and the production has a massive insurance nightmare on its hands.
Bale famously did most of his own stunts, and his commitment to the physicality of Bateman is what makes the chase feel urgent. It isn't just a guy with a saw. It’s a guy who is losing his grip on his carefully curated reality. The sweat is real. The frantic energy is real.
The apartment complex used for the filming—the Montana—provided those long, oppressive hallways. They feel endless. It creates a sense of claustrophobia despite the wide-open spaces. You’ve got this stark contrast between the high-end architecture and the primal, bloody violence occurring within it. Honestly, it’s the perfect metaphor for the 1980s: shiny on the outside, rotting and violent underneath.
Why the Raincoat Matters
The raincoat isn't just a costume choice to keep the blood off Bale’s skin. It’s a shield. Bateman is obsessed with surfaces. He spends the opening of the film describing his morning routine, his exfoliating gels, and his herb mint masks. He can't get dirty. To Bateman, the "mess" of a murder is an inconvenience to his aesthetic.

When he’s revving that chainsaw, he’s trying to maintain his pristine image while indulging his darkest impulses. The clear plastic allows the audience to see his physique—the ultimate symbol of his vanity—while he’s in the middle of a literal bloodbath.
The Stairwell Drop: Real or Impossible?
Then comes the moment everyone remembers. Christie is running down the spiral stairs. Bateman is at the top. He times it. He calculates. He drops the chainsaw.
It hits her. Perfectly.
From a physics standpoint, this is basically a one-in-a-million shot. In the context of the movie, it raises the question: is this actually happening? Many film scholars and fans of the book argue that much of American Psycho takes place in Bateman’s head. The American Psycho chainsaw scene is so over-the-top that it feels like a fever dream.
Consider these points:
- How did no one hear a chainsaw in a luxury Manhattan high-rise?
- How did he get back into his apartment without leaving a trail of blood?
- Why does the chainsaw never run out of gas or stall?
Mary Harron has mentioned in interviews that she didn't want to make it purely "all in his head," but the absurdity is intentional. It’s a hallucination of grandeur and power. Bateman wants to be the protagonist of a horror movie because his real life is so hollow.

The Sound Design of Terror
The audio in this scene is what really gets under your skin. The high-pitched whine of the saw isn't just noise; it’s an assault. It drowns out Christie’s screams. It creates a vacuum where only Bateman’s will exists.
Interestingly, the foley artists had to work overtime to make that saw sound "expensive." It couldn't sound like a cheap tool from a hardware store. It had to sound like a beast. When the saw finally stops after the kill, the silence is deafening. It’s the sound of a man realizing that even after the "big finale," he still feels nothing.
Satire vs. Slasher: The Fine Line
A lot of people miss the joke. That's fine. It’s a dark joke. But the American Psycho chainsaw scene is peak satire because it mocks the slasher genre while participating in it. Bateman is a parody of Jason Voorhees or Leatherface, but he’s doing it in a tuxedo or a raincoat.
He’s the "corporate" version of a monster.
If you look at the way the scene is shot, it uses classic horror tropes. The "final girl" running away. The POV shots. The looming shadow. But because it’s Patrick Bateman—a guy who cares more about his business card than his victims—the scene becomes a critique of the "me" generation. He’s not killing out of passion; he’s killing because he’s bored.
Guinevere Turner, who co-wrote the screenplay and played Elizabeth (another of Bateman's victims), has talked about how the film focuses on the victim's perspective during these chases to highlight Bateman's pathetic nature. He isn't cool. He's a loser with a power tool.

What the Chainsaw Represents
In the 1980s, the chainsaw was the ultimate symbol of blue-collar labor. Seeing it in the hands of a multimillionaire investment banker is jarring. It’s a tool of destruction used by someone who has never built anything in his life.
Bateman doesn't create. He consumes. He destroys.
The saw is an extension of his need to dominate his environment. He can’t just kill Christie; he has to do it with maximum noise and theatricality. It’s his "art." Of course, it’s art that nobody sees, which is the ultimate tragedy for a narcissist like him.
Common Misconceptions About the Scene
- It was filmed in a real apartment: Most of the interior shots were sets. This allowed for the specific "endless hallway" look that makes the chase so effective.
- The chainsaw was real: It was a real saw, but the chain was removed for safety during the chase sequences. The "cut" was added in post-production.
- The blood was excessive: Compared to the book, the movie is actually quite restrained. Harron focused on the threat of violence rather than the gore itself to avoid an NC-17 rating.
How to Analyze the Scene Today
If you're revisiting this film, pay attention to the lighting. The American Psycho chainsaw scene is incredibly bright. Most horror movies hide their monsters in the dark. Bateman operates in the light. He operates in public. He kills in a building full of people.
The fact that he gets away with it isn't a plot hole. It’s the point. The society he lives in is so self-absorbed that a man can chase a screaming woman with a chainsaw through a hallway and nobody will look out their door. They’re too busy listening to Huey Lewis and the News or worrying about their own reservations at Dorsia.
Actionable Insights for Film Enthusiasts:
- Watch the Framing: Notice how Harron keeps Bateman centered. He is the sun in his own twisted universe.
- Listen for the Transition: Watch how the music cuts out and the mechanical roar takes over. It marks the moment Bateman stops pretending to be "normal."
- Compare to the Book: If you have the stomach for it, read the "Chase, Manhattan" chapter in Ellis’s novel. It provides a much deeper (and more disturbing) look into Bateman’s internal monologue during the hunt.
- Look at the Wardrobe: The sneakers. It’s such a small detail, but it shows Bateman is practical about his madness. He knows he can’t sprint in loafers.
The legacy of the American Psycho chainsaw scene isn't just the gore. It’s the image of a man who has everything—money, looks, status—and is still so empty that he has to fill that void with the roar of an engine and a desperate, naked sprint toward nothingness. It remains a masterclass in how to blend tone, social commentary, and pure, unadulterated cinematic terror.
