Psycho Killer (2026) – Review | Serial Killer Movie | Heaven of Horror

Watch Psycho Killer on VOD now

Psycho Killer was directed by Gavin Polone, who has produced a lot of amazing genre movies. These include Stephen King‘s Secret Window (2004), Cold Storage, and Zombieland: Double Tap, while also having produced projects in various other genres. As a director, this is his feature film debut, and I’m sorry to say I think this is the main issue of the finished product.

I say this because the screenplay was written by Andrew Kevin Walker, who also wrote Se7en. Much of what I liked initially about Psycho Killer feels like classic Andrew Kevin Walker, so I’m hesitant to truly believe the story is bad. After all, the iconic Seven could also have been a very strange experience if not directed by David Fincher.

For the record, Seven is far from the only successful script by Andrew Kevin Walker. He also wrote Brainscan (1994), Hideaway (1995), 8MM (1999), Sleepy Hollow (1999), The Wolfman (2010), Windfall (2022), and The Killer (2023). In other words, he is very far from being a one-hit wonder.

I don’t want to recommend that you skip this movie, because the first half of Psycho Killer shows what a brilliant serial killer horror slasher this could have been. So watch it, and try to prepare yourself for an ending that does not live up to that strong opening.

Psycho Killer is out on digital from April 7, 2026.
