Forget the “video game movie” curse; The Mortuary Assistant is a bone-chilling triumph that stands entirely on its own two feet. Starring Willa Holland (Arrow) as Rebecca Owens, the film follows a newly certified mortician whose “overtime shift” quickly devolves into a grueling battle for her soul.

What Makes It Work

The film expertly balances the stomach-churning procedural work of embalming with a spiraling demonic nightmare. Alongside a mysterious mentor played by Paul Sparks (Boardwalk Empire), Rebecca is forced to confront both ancient evils and her own buried traumas. And boy, does she have a lot of them.

Thanks to a full-scale, practical River Fields Mortuary set, the film drips with realism, like you can almost smell the rot and bloat of the bodies through the screen.

The skin effects are hauntingly accurate. The way the flesh moves during surgical scenes is so visceral. I’ve seen a lot of flesh wounds in horror films and in real life, and the bodies, skin, and organs. The Mortuary Assistant (especially in the opening scene) looks so real that I skipped supper after watching it. And that’s saying something. Your girl likes to eat.

Co-written by the game’s creator, Brian Clarke, the movie dives deeper into the demonic mythology. Whether you’ve seen every ending or don’t know a scalpel from a trocar, the story is perfectly self-contained. If you’ve never played the game, or played it a hundred times, the film works equally well, which is hard to do when it comes to game adaptations.

Nailed It

This film does a lot of things right, but the isolation of the night shift is suffocating. Between the darkness of the hallways and the “residents” that refuse to stay still, the film delivers a relentlessly immersive experience. And thankfully, although this movie is filled with dark rooms and shadows, it’s easy to see every little thing. Don’t you hate it when a movie is so dark that you can’t see what’s happening? It’s one of my pet peeves.

The oh-so-awesome Jeremiah Kipp directs the film and has made something absolutely nightmare-inducing. Kipp recently joined us for an interview, took us inside the film, discussed its details and the game’s lore, and so much more. I urge you to check out our interview. He’s awesome!

The Verdict

This isn’t just a cash-grab; it’s a high-effort adaptation that respects the source material while elevating the horror genre. With incredible special effects and a powerhouse cast, it’s the kind of movie that will make you rethink working late ever again. Dropping on Friday the 13th, this is a must-watch for horror fans. It’s grisly, intelligent, and genuinely terrifying.
