There is something immediately useful about a mortuary as a horror setting. It does not need much dressing up. Strip away the music, the shadows and the demonic mythology, and you are still left with one person alone at night, surrounded by the dead, trying to behave professionally while every survival instinct in their body is telling them to leave.
The Mortuary Assistant understands that. Based on Brian Clarke’s acclaimed horror game, Jeremiah Kipp’s film adaptation takes a premise that could easily have become a procession of jump scares and finds something more tactile, grimy and unnerving inside it. This is possession horror with cold hands, fluorescent lights and practical gore, and while it does not reinvent the demonic wheel, it knows exactly which corners of the room to leave dark.
Willa Holland plays Rebecca Owens, a newly certified mortician whose first proper night shift at River Fields Mortuary goes about as badly as a first proper night shift at a horror-movie mortuary possibly can. Bodies move when they should not. Lights flicker. Strange noises travel through the building. The dead refuse to stay passive. Before long, Rebecca is not just dealing with the physical business of embalming, but with hallucinations, buried trauma and the growing suspicion that something has latched onto her.
It is a strong setup because the job itself is already intimate and unsettling. The film is at its best when it leans into the procedural detail of mortuary work, the gloved hands, the instruments, the clinical language, the awful stillness of a body on a table. Kipp makes good use of that environment, letting the horror creep in around the edges rather than immediately overwhelming it. A twitch here. A sound from somewhere it should not be. A face that looks different when Rebecca turns back. It is familiar stuff, but handled with enough confidence to make it work.
The risk with any game-to-film adaptation, especially one built around first-person dread, is that the loss of control will flatten the experience. Watching someone else investigate a haunted workspace is not the same as having to do it yourself. Like many game adaptations before it, The Mortuary Assistant cannot fully replicate that interactive tension, but it compensates by pushing Rebecca’s psychological unravelling to the front. The scares are not only about what is in the building. They are about what the building, and whatever is using it, can drag out of her.
Holland gives the film a steady emotional centre. Rebecca could easily have become a stock troubled heroine, all trauma flashbacks and panicked breathing, but Holland plays her with enough restraint to keep the character grounded. She is frightened, obviously, but she is also trying to do a job, trying to stay rational, trying to keep moving through a night that becomes increasingly impossible to explain. That tension between professional routine and supernatural collapse is where the film finds most of its best moments.
Paul Sparks is well cast as Raymond Delver, Rebecca’s enigmatic mentor and the kind of man who clearly knows far more about demonic activity in the workplace than he initially lets on. Sparks has a naturally off-centre presence, and the film uses that well. Raymond is helpful, but never entirely comforting. He belongs to that familiar horror tradition of older men with rules, secrets and a worryingly calm attitude towards the impossible. The more we learn about River Fields and its rituals, the more his guidance starts to feel less like mentorship and more like damage control.
Where the film works best is in its physical horror as the welcome sight of practical effects give The Mortuary Assistant a nasty little edge in a CGI saturrated genre. Possession horror has been through this territory many times before, and The Mortuary Assistant cannot entirely escape the usual beats: the tormented protagonist, the hidden past, the ritual logic, the entity that knows exactly which emotional wounds to press. At times, you can feel the film arranging its mythology rather than letting it breathe.
That said, there is enough atmosphere, craft and horrible texture here to carry it through. Kipp keeps the film moving, which is no small feat given the contained structure. More importantly, the film understands that possession stories work best when the threat feels invasive. The demon is not just trying to kill Rebecca. It is trying to occupy her, rewrite her, turn her own memories and guilt into tools. That is where the film finds its sting.
It may not convert anyone exhausted by demonic horror, but for those still happy to spend a night in a cursed building with bad lighting, worse secrets and a body that absolutely should not have moved, this is a solid shift. It’s a creepy possession movie with a pleasingly gruesome bedside manner.
The Mortuary Assistant is out now on Digital, DVD, and Blu-ray.
