You probably know her from First Kill or maybe that stint on White Lotus that had everyone talking, but for horror junkies, Sarah Catherine Hook is etched into the brain for something way more sinister. I’m talking about her role as Debbie Glatzel in The Conjuring: The Devil Made Me Do It. Honestly, jumping into a franchise that has grossed over $2 billion is a massive flex for any actor, but Sarah Catherine Hook didn't just show up; she anchored the emotional stakes of a movie based on one of the weirdest legal cases in American history.
It’s easy to forget that the third Conjuring film took a hard left turn away from the "haunted house" trope. Instead, we got a legal thriller mixed with satanic totems. At the center of that chaos was Sarah Catherine Hook. She played the girlfriend of Arne Cheyenne Johnson, the first person in U.S. history to claim demonic possession as a defense for manslaughter.
Why Sarah Catherine Hook in The Conjuring Mattered So Much
When you look at the 2021 release of The Devil Made Me Do It, the pressure was high. Patrick Wilson and Vera Farmiga are the faces of the franchise, sure. But the movie fails if you don't care about the victims. Sarah Catherine Hook had the unenviable task of playing a woman watching her younger brother, David, get contorted like a pretzel by a demon, only to then watch her boyfriend, Arne, take that curse upon himself.
She brought this raw, 1980s Connecticut vibe that felt authentic. It wasn't just "scream queen" energy. It was "I am trying to keep my family from literally imploding" energy.
The Real Debbie Glatzel
Sarah Catherine Hook wasn't just playing a character written in a vacuum. She was portraying a real person. Debbie Glatzel was there in 1980. She was there when Ed and Lorraine Warren showed up. She was there during the exorcism of her brother. Hook has mentioned in various press circuits that she felt a weight of responsibility to get that right.
The real-life case of Arne Johnson is harrowing. He stabbed his landlord, Alan Bono, over twenty times. The defense argued that Arne wasn't a murderer—he was a vessel. To make a movie audience buy into that, you need a performance that bridges the gap between the supernatural and the courtroom. Hook did that. She made the love story between Debbie and Arne feel like the only thing keeping the movie from spiraling into pure nihilism.
Behind the Scenes: Not Just CGI and Jump Scares
If you've ever seen the "making of" clips for The Conjuring: The Devil Made Me Do It, you know the production design was intense. Sarah Catherine Hook has talked about how immersive those sets were. There’s one scene in particular—the one in the kennel where Arne (played by Ruairi O'Connor) starts losing his mind.
It's loud. It's dirty. It's claustrophobic.
Hook’s performance in these moments is what grounds the film. While the director, Michael Chaves, is busy throwing jump scares at the audience, Hook is focusing on the micro-expressions of grief and terror. She’s the audience surrogate. When she looks terrified, we feel it because she isn’t just reacting to a man in a rubber suit; she’s reacting to the loss of the person she loves.
Working with the Warrens (In Character)
A huge part of the Conjuring experience for any actor is sharing the screen with Wilson and Farmiga. Sarah Catherine Hook held her own. There's a specific chemistry required to play alongside the Warrens. You have to treat them like the experts they are while still maintaining your own character's agency.
In the film, Debbie Glatzel is the one who refuses to give up on Arne. She’s the one working with the Warrens to find the occultist responsible for the curse. Hook plays this with a certain grit. It would have been easy to play Debbie as a passive victim, but instead, she’s active. She’s a fighter.
The Cultural Impact of the Performance
Let’s be real: horror movies are often seen as a "start" for young actors. But The Conjuring universe is different. It’s a prestige horror brand. For Sarah Catherine Hook, this was a launching pad.
Shortly after the film, she landed the lead in Netflix's First Kill. While that show was a vampire romance, the "Final Girl" DNA she cultivated in The Conjuring was clearly visible. She knows how to handle genre material without making it feel campy. That's a rare skill.
Does it hold up?
Watching The Devil Made Me Do It years later, the performances are actually the strongest part of the film. While some critics felt the move away from the "haunted house" formula was risky, the human element remained strong. That’s largely due to the central trio of Hook, O'Connor, and the Warrens.
If you go back and watch the scenes involving the "Occultist," you’ll notice how Hook’s character reacts to the supernatural elements. She isn't just screaming. She's processing. It’s a nuanced take on a role that could have been very one-dimensional.
Facts About the "Devil Made Me Do It" Case
To understand why Sarah Catherine Hook's role was so pivotal, you have to look at the actual history.
- The Date: The murder happened on February 16, 1981, in Brookfield, Connecticut.
- The Victim: Alan Bono, a kennel manager.
- The Possession: It allegedly started with David Glatzel, Debbie's 11-year-old brother.
- The Defense: Martin Minnella, the lawyer, tried to enter a "not guilty by reason of demonic possession" plea. The judge, Robert Callahan, famously rejected it.
Sarah Catherine Hook had to portray a woman who truly believed—to her core—that her boyfriend was innocent because of a literal devil. Whether you believe the real Debbie Glatzel or not, Hook’s job was to make you believe that Debbie believed it. That's a tricky layer of "truth" to play, and she nailed it.
The Physicality of the Role
Horror is a physical genre. There are scenes in the film where Hook is running through woods, dealing with practical effects, and reacting to intense lighting cues.
She's spoken about the exhaustion of these shoots. You’re essentially crying or screaming for 12 hours a day. It takes a toll. But that exhaustion often translates to better performances in horror. It adds a layer of real-world fatigue that makes the character feel more vulnerable.
What Most People Get Wrong About Sarah Catherine Hook and Horror
A lot of fans think Sarah Catherine Hook is "new" to the scene, but she’s been grinding for a while. She’s a classically trained singer. She has a background that involves a lot of discipline. You can see that discipline in her work in The Conjuring.
She doesn't waste movements.
Another misconception? That her role was just a supporting one. In reality, Debbie Glatzel is the heart of the movie. Without her, Arne is just a guy who committed a crime. With her, it's a tragedy about a family being torn apart by forces they don't understand.
The "Scream Queen" Label
Is she a scream queen? Maybe. But she’s more of a "Struggle Queen." She plays characters who are in the thick of it, trying to figure a way out. She isn't just waiting to be rescued. In The Conjuring, she's the one providing the Warrens with the clues they need. She's the bridge between the supernatural world and the mundane world of 1980s suburbia.
Where to See Her Next
If you loved her in The Conjuring, you've probably already tracked down First Kill on Netflix. Even though it was canceled after one season (which still stings for a lot of fans), her performance as Juliette Fairmont is top-tier.
She’s also moved into more prestigious territory with The White Lotus Season 3. This is a huge jump. Going from the scares of The Conjuring to the biting social satire of Mike White's world shows her range. She’s not going to be pigeonholed into one genre.
Key Takeaways from Her Conjuring Performance
- Emotional Anchoring: She provided the human stakes in a film filled with CGI demons.

- Genre Mastery: She proved she could handle the physical and emotional demands of a major horror franchise.
