“It is not the strongest of the species that survives, nor the most intelligent, it is the one that is most adaptable to change.” — Sophia
Under Paris is one of those movies that grabs you by the throat and doesn’t let go—literally, in this case. Directed by Xavier Gens, the mind behind gritty, high-octane thrillers like Frontier(s) and The Divide, this creature feature dives headfirst into the claustrophobic nightmares lurking beneath the City of Light. And let me tell you, if you’ve ever romanticized the Parisian catacombs, this film will cure you of that real quick.
The story kicks off with a team of scientists exploring the unexplored tunnels under Paris, only to stumble upon something that definitely shouldn’t exist. What starts as a routine expedition turns into a fight for survival when they realize they’re not alone down there. The creatures in question are blind, feral, and terrifyingly fast, with a taste for human flesh. It’s The Descent meets Tremors, but with a distinctly French flair. The film wastes no time setting up its premise, throwing the audience into the dark, cramped corridors where every shadow could be a predator. The tension is palpable from the jump, and Gens doesn’t bother with slow-burn scares—this is a full-throttle horror ride.
What makes Under Paris stand out is its commitment to practicality. The creatures are brought to life with a mix of practical effects and CGI, and for the most part, it works. The designs are grotesque yet believable, with elongated limbs, jagged teeth, and a primal way of moving that makes them feel like something out of a nightmare. The practical effects, in particular, give the creatures a tangible weight that CGI alone often struggles to achieve. When they’re on screen, you believe they’re real, and that’s half the battle in a monster movie. The sound design deserves a shoutout too—the way the creatures communicate through clicks and hisses is unsettling in the best way, adding to the immersive dread.
The characters are, admittedly, a mixed bag. The cast is led by a group of scientists and urban explorers, each with their own quirks and backstories, but the film doesn’t spend much time fleshing them out. This is a survival horror flick, not a character study, so don’t expect deep emotional arcs. That said, the actors do a solid job with what they’re given. The standout is probably the team’s leader, whose growing desperation as the situation spirals out of control feels authentic. There’s also a refreshing lack of the usual horror-movie stupidity—most of the characters make decisions that, while not always smart, at least feel human. They panic, they argue, they try to rationalize the irrational, and it makes their plight all the more relatable.
The setting is a character in its own right. The labyrinthine tunnels under Paris are a horror fan’s dream—narrow, dimly lit, and filled with the kind of eerie silence that makes every distant noise sound like a death sentence. Gens and his cinematographer make the most of the claustrophobic environment, using tight camera angles and rapid cuts to keep the audience on edge. There’s a sequence early on where the team’s headlamps flicker, plunging them (and us) into total darkness, and it’s a masterclass in building tension without relying on jump scares. The film also does a great job of playing with sound, or the lack thereof. In the quiet moments, all you hear is the characters’ ragged breathing and the distant, unsettling skittering of something inhuman.
If Under Paris has a weakness, it’s that it doesn’t always know when to slow down. The pacing is breakneck, which works for the most part, but there are moments where a little breathing room would’ve helped. Some of the CGI, particularly in the wider shots, can look a bit rough, though it’s never bad enough to pull you out of the movie. And while the creatures are terrifying, their backstory is a bit thin. The film hints at a larger mythology—something about evolution and isolation—but it’s never fully explored. That’s not necessarily a dealbreaker, but it does leave you with a few unanswered questions.
All that said, Under Paris delivers exactly what it promises: a tense, visceral, and often downright terrifying descent into madness. It’s a film that understands the assignment—give the audience scares, gore, and a sense of dread that lingers long after the credits roll. Gens has a knack for blending horror with social commentary, and while Under Paris doesn’t dive as deep into the latter as some of his other work, it’s still there in the margins. The idea of something monstrous lurking beneath the surface of one of the world’s most romanticized cities is a potent one, and the film doesn’t shy away from the metaphorical implications.
In the end, Under Paris is a must-watch for horror fans, especially those who appreciate their scares with a side of action. It’s not a perfect movie, but it’s a damn effective one. It’s the kind of film you’ll want to watch with the lights off, the volume up, and maybe a friend or two to clutch onto when things get really intense. And trust me, they do. Xavier Gens has crafted a creature feature that’s as brutal as it is brilliant, and it’s a testament to his skill as a director that, even in the darkest, most chaotic moments, you’re never quite sure what’s going to happen next. Just don’t blame me if you start side-eying manhole covers after this one.
