Willem Dafoe is a shapeshifter. Honestly, there is no other way to describe a man who can play a saint in one film and a comic book villain in the next without breaking a sweat. But his turn as Detective Donald Kimball in the 2000 cult classic American Psycho is something different entirely. It isn't just a supporting role. It’s a psychological experiment.
Most people watch Mary Harron’s adaptation of the Bret Easton Ellis novel for Christian Bale’s translucent skin and those blood-soaked raincoats. They stay for the Huey Lewis and the News trivia. Yet, the engine that keeps the middle of the movie tension-wire tight is Willem Dafoe in American Psycho. He shows up at Pierce & Pierce with a smile that doesn't quite reach his eyes and a series of questions that make Patrick Bateman—and the audience—question reality.
The Three Takes Technique You Probably Didn't Notice
Director Mary Harron did something brilliant with Dafoe. She knew that to make a movie about a serial killer interesting, the "cat and mouse" game had to feel unstable.
So, she had Dafoe film every single scene with Bateman in three distinct ways.
In the first take, Dafoe played Kimball as if he knew Patrick Bateman killed Paul Allen. He was smug. He was just waiting for a slip-up. In the second take, he played it like he suspected Bateman but didn't have the proof yet. In the third? He played Kimball as a totally clueless, slightly bumbling detective who genuinely thought Bateman was a nice, successful guy.
Then, in the editing room, Harron spliced these takes together.
The result is a performance that feels erratic and terrifyingly unpredictable. One moment, Kimball looks like he’s about to slap the handcuffs on; the next, he’s laughing at a joke about "Oliver Peoples" glasses. This wasn't just a stylistic choice. It was a way to mirror Bateman’s own internal crumbling. When you watch Willem Dafoe in American Psycho, you aren't just watching a detective investigate a crime. You are watching a man become a Rorschach test for a psychopath's guilt.
Why Donald Kimball Is the Only "Real" Person in the Room
The world of American Psycho is populated by shallow husks. Everyone looks the same. Everyone has the same haircut, the same Valentino suits, and the same hollow priorities.
Kimball is an outsider.

He enters this sterile, high-finance environment like a specimen from another planet. Dafoe brings a grounded, slightly rumpled energy to the role that contrasts sharply with the porcelain perfection of the bankers. When he sits in Bateman’s office, he doesn't fit. He’s too "human."
This humanity is exactly what makes Bateman so nervous. You can't predict a human being using a spreadsheet or a business card's watermark.
There's a specific scene where they’re discussing Paul Allen's disappearance over lunch. Watch Dafoe's eyes. He does this thing where he pauses just a millisecond too long before responding. It’s unnerving. It suggests a depth of knowledge that may or may not exist. Guilt-ridden people project their fears onto silence, and Dafoe uses silence like a weapon.
The Mystery of the Paul Allen Investigation
Did Kimball ever actually find anything?
Probably not.
In the book and the film, the ambiguity is the point. The satire of the 1980s is that everyone is so self-absorbed that even a mass murderer can't get caught because nobody is paying enough attention to realize who is who. Paul Allen might not even be dead. He might be in London.
Kimball represents the possibility of justice. But in the end, even he is swallowed by the vapidity of the era. He vanishes from the plot because, in Bateman's world, a detective is only relevant as long as he’s a threat to Bateman’s ego. Once the ego finds a way to rationalize the crime—or once the world proves it doesn't care—the detective becomes obsolete.
Dafoe vs. Bale: An Acting Masterclass
Working with Christian Bale is no easy task. Bale is known for being... intense. During the filming of American Psycho, he stayed in character, avoiding social interaction with the cast to maintain that sense of isolation.

Dafoe, a veteran of the avant-garde theater scene (The Wooster Group), was the perfect foil.
While Bale is all rigid lines and controlled breathing, Dafoe is fluid. He leans back. He tilts his head. He uses his face—that incredible, expressive face—to fill the gaps in the script. It’s a battle between a man trying to be a machine (Bateman) and a man who is unapologetically organic (Kimball).
I’ve always felt that the "Sussudio" scene gets all the glory, but the real tension is in the office. Every time Willem Dafoe in American Psycho leans forward to ask about a dinner reservation at Dorsia, the stakes feel higher than any chainsaw chase.
The Cultural Longevity of the Performance
Why are we still talking about this twenty-five years later?
It’s partly the memes, sure. But it’s also because Dafoe’s performance taps into a universal anxiety. We’ve all been in a situation where we feel like someone "knows" our secret, even if that secret is just that we didn't actually read the book for the book club.
Kimball is the personification of that "knowing" look.
Critics at the time, like Roger Ebert, noted that the film’s strength was its refusal to be a standard slasher. Dafoe is a huge part of that. If Kimball had been a standard hard-boiled detective, the movie would have felt like a procedural. Instead, it feels like a fever dream.

"You were with Courtney Rawlinson," he says.
The way Dafoe delivers that line is masterful. Is he relieved? Is he disappointed? Is he mocking him? By using those mixed takes Harron requested, Dafoe manages to sound like he’s giving Bateman a "get out of jail free" card while simultaneously holding a gun to his head.
It’s a masterclass in nuance. Most actors want to be "clear." They want the audience to know exactly what the character is thinking. Dafoe is brave enough to be muddy. He knows that in a story about a man losing his mind, the most helpful thing a supporting actor can do is provide more questions than answers.
Actionable Insights for Film Buffs and Creators
If you want to truly appreciate what happened during the production of this film, or if you’re a creator looking to add depth to your own work, consider these takeaways:
- The Power of Ambiguity: Next time you’re writing or performing, try the "Three Takes" method. Perform a scene with three entirely different motivations and see how the "middle ground" creates a more complex character than a single-note performance ever could.
- Contrast is King: Notice how Dafoe uses his wardrobe and physical movement to stand out from the "yuppie" environment. To make a character memorable, make them the "wrong" shape for the room they are in.
- Watch the Eyes: Study the lunch scene specifically. Watch how Dafoe uses eye contact to dominate the space without raising his voice. It's a lesson in quiet authority.
- Revisit the Source: If you’ve only seen the movie, read the Bret Easton Ellis novel. It provides a much darker context for Kimball’s appearances and helps explain why Dafoe played him with such a haunting, ethereal quality.
The legacy of Willem Dafoe in American Psycho isn't just that he was "in a good movie." It's that he understood the assignment perfectly: be the mirror that shows the protagonist—and the audience—exactly how fractured they really are.
To see more of this specific era of Dafoe's career, look into his work in The Boondock Saints (1999) and Shadow of the Vampire (2000). You'll see an actor at the absolute peak of his experimental powers, willing to take risks that most leading men wouldn't touch with a ten-foot pole. He didn't just play a detective; he played the very idea of suspicion. And that is why we are still captivated by those scenes today.
