If you’ve ever wanted to watch an entire movie built around the concept “What if a Kinder Surprise toy was evil, but also incredibly boring?” then The Jack in the Box is your moment. Everyone else may want to quietly back away from the display case.
This 2019 British horror film, directed by Lawrence Fowler, takes a promising premise—a demonic jack-in-the-box—and manages to wring out the absolute minimum possible terror, tension, or common sense. It’s like someone heard the phrase “possessed clown toy” and said, “Cool, but what if we made it feel like a straight-to-DVD episode of Cash in the Atticwith murder?”
Antiques Roadshow From Hell (But Mostly Just From Nowhere)
We open with a man unearthing a buried box in a field, because nothing bad has ever come from digging up random objects that look like cursed props from the discount bin of a Halloween store. He brings it home, his wife immediately hates it (the only character in the entire film with working instincts), and is promptly murdered by a demon clown that pops out of the box.
You’d think starting with “murder clown erupts from cursed toy and slaughters someone in their own kitchen” would set a wild tone. Instead it feels like a preview for a much better film that never shows up.
Years later, we meet our hero, Casey, an American trying to rebuild his life in a small British town after his girlfriend was killed during an armed robbery—because subtlety is for people with higher budgets, apparently. He gets a job at an antiques museum, which is essentially a graveyard for random objects and the pacing of this movie.
There he meets Lisa, his co-worker, who has a sick mother, no joy, and the energy of someone who’s been stuck in this script for three reshoots. She introduces him to the “junk room” of the museum, where objects of “dubious value” are stored. Unfortunately, that description also applies to most of the characters.
In this room, Casey finds the Legendary Box of Doom™ and a rare book, because horror films have an unwritten rule that demons must come with reading material.
The Demon, the Thieves, and the Complete Lack of Subtlety
The jack-in-the-box is triggered the moment Casey touches it, its handle turning on its own, and out pops a clown puppet that looks less “ancient cursed artifact” and more “party store item that came with a recall notice.” But credit where it’s due: in its full demon form, the Jack itself—played by Robert Strange in prosthetics—is one of the few genuinely decent things in the film. It’s tall, gaunt, and creepy. It’s also tragically stuck in a movie that has no idea what to do with it beyond “show up and stab people occasionally.”
Two thieves break in that night, because apparently we needed a scene to confirm that yes, the clown is offended by insults. One of them mocks the toy, and the demon emerges and kills both of them for the unforgivable crime of weak banter. It should be a bloody, wild set piece. Instead it plays like a training simulation for “intro to creature attacks” in film school.
Casey returns the next day to find… nothing. No bodies. No obvious bloodbath. Just an open door and a missed opportunity for the film to become interesting.
Exposition, Guilt, and Yawning
In shuffles an antiques expert, who exists solely to look at the Jack-in-the-box and say, “Ah yes, this is rare, probably cursed, and definitely part of some spooky legend.” He delivers the standard Demon 101 exposition: some jack-in-the-boxes allegedly house evil entities. Then he leaves the movie like a wise man who’s realized he’s above this.
Meanwhile, Casey can’t sleep because he’s wracked with guilt over ignoring his girlfriend’s last phone call before she died. This trauma should make him feel layered and tragic. Instead, it mostly functions as an excuse for him to look tired and confused while the plot inches forward like it’s stuck in molasses.
A museum visitor shows up. Casey is too sleepy to properly help her, which the film wants us to understand as a serious professional failing. Then the demon kills her off-screen. Casey hears a scream, shrugs, and goes back to his shift in the thrilling world of glass cabinets and badly lit hallways.
Soon, her photo appears on a “missing person” sign in town, and Casey finally starts to suspect something is wrong. You know, now.
The World’s Least Professional Demonologist
After the cleaner goes missing too (killed by the demon in a scene that at least shows some effort with gore), a detective questions Casey. Casey—who is definitely wanted by HR at this point—floats the idea that the disappearances might be supernatural. The detective reacts like a man who’s just realized he’s not going to retire peacefully.
Casey seeks help from Maurice, a demonologist, because when someone in a horror film Googles “cursed box what do I do,” the answer is always “eccentric expert with a semi-functional moral compass.” Maurice, however, doesn’t answer his calls at first. Perhaps he saw the script.
By the time Casey corners him at home, Maurice finally shares the rules of the curse: the demon must claim a certain number of lives, and can only be trapped back in the box through a ritual—but only if no piece of the demon is left outside. The fact that the movie screams this condition at you is a sure sign it’ll be ignored in the third act like a fire exit in a slasher flick.
Maurice also suggests running away, which is the most rational line in the film.
Everyone Ignores Red Flags, The Movie Continues
Casey doesn’t run. Instead he investigates the previous owner of the Jack-in-the-box—the poor husband from the opening scene. The man confirms that the demon killed his wife and nobody believed him. Apparently, in this universe, “my wife was killed by a jack-in-the-box demon” does not hold up well in court.
Casey’s boss, Rachel, unimpressed by his talk of demons and visions, fires him for being weird. It’s hard to argue with her. If your employee is sleep-deprived, morbidly obsessed with one object, and keeps mentioning curses to customers, HR will have thoughts.
Lisa, who used to think Casey was sweet, now thinks he’s dangerously unwell. Their argument is meant to be dramatic. Mostly, it’s just another scene of everyone refusing to believe the extremely believable idea that the creepy clown box that keeps appearing everywhere might actually be a problem.
Final Fight: Jacked Up but Still Half-Baked
Naturally, everything converges back at the museum. The demon goes on a mini-rampage, devours Rachel, and goes after Lisa. Casey arrives in time to rescue Lisa and wrestle with the demon in a climax that feels like someone staged a boss fight in an empty gift shop.
He manages to shove Jack back into the box and slam the lid, saving the day—almost. One of the demon’s claws breaks off and remains outside the box. Remember Maurice’s warning? Of course you do. The script certainly did. The police arrive just in time to see a panicked young man, a bunch of missing people, and a suspiciously occult-looking box. They do the sensible genre thing and arrest Casey for murder.
Lisa swears she’ll testify for him. The authorities politely decide to ignore the woman who just survived a nightmare clown and instead believe the more reasonable theory: that this exhausted antiques clerk personally killed multiple people and hid their bodies using, presumably, museum magic.
Lisa takes it upon herself to finish the job by burying the box, because that always works out great in folklore. But because the claw is still out, the demon is technically still free. Just as Casey, during interrogation, realizes what that crime-scene photo of the claw means, Jack pops out underground and eats Lisa too.
And with that, the film somehow manages to fridge the one sympathetic character and leave the demon intact for a sequel. Ambitious, in a bleak way.
Jack-Off Horror
In the end, The Jack in the Box is a film built around a single halfway decent monster design and an ocean of missed potential. The pacing is sluggish, the scares are predictable, and the characters consistently make choices that suggest they’ve never seen a horror movie, or perhaps a functioning brain.
It’s not aggressively awful; it’s worse than that—it’s aggressively mediocre. A movie about a cursed children’s toy should at least be deranged fun. Instead, it’s like watching someone slowly read the instruction manual for a haunted music box and occasionally shouting “Boo!” at you from the footnotes.
If you have a burning desire to see a demonic clown pop out of a box, kill people in a museum, and still somehow make you check your phone, this one’s for you. Everyone else? Maybe leave this Jack buried.
