The 'Se7en' Writer's New Slasher Hits Hulu Today — Here's What Critics Missed
Andrew Kevin Walker, the screenwriter who gave the world the most famous twist ending in modern horror, is back with a new serial-killer thriller — and it's quietly landing on Hulu and Disney+ today, May 29, after a rough theatrical run. The film is called Psycho Killer, and despite a brutal reception in February, it's worth a second look before everyone writes it off.
Here's why the streaming drop is more interesting than the box office story.
A Marquee Talent Roster Behind a Modest Slasher
Psycho Killer opened in theaters on February 20, 2026 from 20th Century Studios and New Regency, and it disappeared fast — earning roughly $2.5 million domestic against a reported $10 million budget. The critical reception was harsh: a 9% score on Rotten Tomatoes and 26 on Metacritic.
But under the hood, the credits look like a horror fan's dream lineup.
The screenplay is from Andrew Kevin Walker, whose previous horror-thriller credits include David Fincher's Se7en and Tim Burton's Sleepy Hollow. The director is Gavin Polone, the longtime producer behind Zombieland and Panic Room, making his feature directorial debut. Producing alongside Polone is Roy Lee, the same producer who brought us Barbarian, Late Night with the Devil, and the recent Stephen King adaptations.
And the cast pulls names from across horror's bench:
- Georgina Campbell (Barbarian) as Jane Archer, a Kansas Highway Patrol officer
- James Preston Rogers (The Blackening) as Richard Joshua Reeves, the killer
- Malcolm McDowell (A Clockwork Orange, Rob Zombie's Halloween) as Mr. Pendleton
- Grace Dove (The Revenant) as Agent Becky Collins
- Logan Miller (Escape Room) as Marvin
That's not a "straight to streaming" lineup on paper. That's a wide-release slasher swing.
The Plot: A Highway Patrol Cop vs. the "Satanic Slasher"
The premise is classic American slasher with a road-movie spine.
Georgina Campbell plays Jane Archer, a Kansas Highway Patrol officer whose life is shattered when her state trooper husband is brutally murdered on a routine stop. Her grief turns into pursuit. The killer — nicknamed by the press as "the Satanic Slasher" — is revealed to be a murderous occult preacher embarked on a cross-country killing spree, with a final ritualistic agenda far darker than a single roadside execution.
As Jane tracks him across multiple states, she also discovers she's pregnant. The chase ultimately leads to a confrontation at a nuclear power plant, where the killer plans a suicide bombing he believes will "appease Satan."
It's pulpy, violent, and unapologetically theological in the way only an Andrew Kevin Walker script can be. The R rating tells you everything: "strong bloody violence, strong sexual content, graphic nudity, drug use, and language."
Why the Theatrical-to-Streaming Pivot Is the Real Story
This is one of the fastest theatrical-to-streaming windows we've seen from a major studio horror release in 2026. From February 20 to May 29 is roughly 13 weeks — well under the 17-week industry standard, and lightning-fast compared to Universal/Blumhouse horror windows that can stretch to four months or more.
Studios usually use the streaming window to rehabilitate underperforming theatrical releases. The bet here is straightforward: Walker's name, Campbell's Barbarian fanbase, and Disney+'s broad reach can find an audience that the marketing campaign couldn't.
It's a familiar pattern. Smile 2, Imaginary, and Night Swim all found stronger second lives on streaming after lukewarm theatrical runs. Slasher pictures with strong leads and a clear hook tend to outperform on home viewing — without the pressure of opening weekend tracking, they get judged on what they actually are: a Friday-night watch.
And Campbell, in particular, has been singled out even by the harshest reviews. The Hollywood Reporter review called her performance "solid" and "thoughtful" against a backdrop critics described as derivative. The post-Barbarian run she's been on — His House before, Suitable Flesh and now Psycho Killer — has quietly made her one of the most reliable scream-queen presences working today.
What to Watch For When You Stream It
Three things worth tracking when you queue it up on Hulu:
The Andrew Kevin Walker signature. His scripts traffic in extreme religious mania and grim moral architecture. The "Satanic Slasher" preacher framework, the cross-country killing spree, the nuclear-plant finale — these all bear his fingerprints from Se7en. The question is how much of that signature makes it through Polone's directorial filter on a first feature.
Malcolm McDowell's role. Pendleton is one of the more curious supporting parts in recent horror. McDowell rarely takes a slasher role unless the character has a reason to exist. Worth watching what hand he plays.
Georgina Campbell's range. Barbarian gave her a panic-driven survivor performance. Psycho Killer asks her to carry a grief-revenge arc across an entire feature. The pivot from horror-survivor to horror-hunter is one of the harder turns in the genre.
Streaming horror has a different math than theatrical. A 9% Rotten Tomatoes score and a $2.5 million opening might be a theatrical death sentence, but it's not necessarily a verdict on the movie. Psycho Killer is now a Hulu watch, available alongside the Alien franchise and the Predator catalog on a single subscription. That repositioning matters.
The Bigger Picture: Major Studio Horror in 2026
Psycho Killer is part of a broader 2026 pattern: major studios swinging on original horror IP and missing on opening weekend, then finding life on streaming. The horror calendar this spring has been crowded — Backrooms, Obsession, Passenger, Hokum — and audience attention has been hard to capture for any single title.
The lesson studios are learning: a brand-name screenwriter and a strong lead aren't enough by themselves to break out theatrically anymore. You need a hook the trailer can sell in fifteen seconds. Psycho Killer's marketing tried to lean on the Se7en connection, but for a younger horror audience that didn't see Se7en in theaters, that anchor doesn't pull weight.
Streaming changes the equation. On Hulu, Psycho Killer gets compared not to other 2026 theatrical horror, but to the dozens of slashers in the algorithm queue. And against that competition, a film with Walker, Campbell, McDowell, and Polone has real ammunition.
Should You Watch It?
If you loved Barbarian and want to see Campbell carry a feature, queue it up. If you're a Walker completist, queue it up. If you want a meat-and-potatoes slasher with a road-movie engine and a religiously-charged villain, queue it up.
If you're expecting Se7en 2, adjust your expectations down. This isn't that movie. It's a smaller-scale slasher with serious craft behind it, and a lead performance worth the ride.
Psycho Killer hits Hulu and Disney+ today, May 29.
