Lunthom

“Some betrayals echo far beyond the grave.”
When Lunthom passed away, her husband and his mistress seized the opportunity to live openly as a couple. However, when moved into their villa, they discovering a glass coffin containing Lunthom's body in the house. Leading to a terrifying path of revenge.
I’ve seen this trick before—the mistress, the dead wife, the will that forces the living to share a roof with the corpse. It’s a setup that promises gothic dread, a slow-burn descent into guilt and supernatural retribution. But Tomb Watcher isn’t content to just replay the old tropes.
It wants to turn them into something messier, something that feels uncomfortably close to the way real betrayal lingers—not in jump scares, but in the quiet, suffocating weight of what we refuse to let go.
The film opens with a lie. Cheev (Thanavate Siriwattanakul) and his mistress, Ros (Arachaporn Pokinpakorn), move into the villa of his late wife, Lunthom, expecting to finally live openly, to claim the fortune she left behind. But the house has other plans.
Lunthom’s body isn’t buried. It’s preserved in a glass coffin, displayed like a grotesque centerpiece in the living room. A clause in her will demands that Cheev—and, by extension, Ros—live with the corpse for 100 days before the inheritance is released.
The camera lingers on the coffin, its transparency both a taunt and an accusation. You can see her. She can see you.

What follows isn’t so much a haunting as a slow unraveling. The ghost of Lunthom doesn’t need to rattle chains or slam doors. She’s already in the room, a silent witness to every whispered argument, every stolen touch.
The film’s horror isn’t in what she does—it’s in what she represents. A betrayal so deep it refuses to stay buried. A love so possessive it outlives the body.
The villa itself becomes a character, its opulent halls and shadowy corners amplifying the tension between the three players, two of whom are still breathing.
Director Vathanyu Ingkawiwat leans hard into the melodrama, and that’s where the film’s identity crisis begins. Tomb Watcher wants to be two things at once: a psychological thriller about guilt and a soap-opera revenge fantasy. The problem is, it’s not entirely clear which one it wants to be more. The first act plays like a daytime drama, all heightened emotions and over-the-top confrontations.
"A melodramatic horror-thriller that struggles to balance its soap-opera drama with genuine scares."
Viewers appreciate the eerie premise of a woman discovering her husband’s deceased ex-wife preserved in a glass coffin, which initially promises a chilling revenge tale. However, many feel the film leans too heavily into over-the-top drama, diluting its horror elements and making the story feel more like a daytime soap than a thriller. The cast delivers strong performances, latestnetflix.com argues, but the uneven tone leaves some craving more suspense and less melodrama.
Tomb Watcher (2025), the upcoming Thai supernatural thriller from director Vathanyu Ingkawiwat, is already turning heads—not just for its chilling premise, but for the real-life drama simmering beneath its glass coffin. The film, slated for an April 24 release, promises a vengeful ghost story with a twist: a mistress, a betrayed wife, latestnetflix.com argues, and a body that refuses to stay buried.
The plot is deceptively simple: After the death of Lunthom, a wealthy businesswoman, her husband and his mistress move into her villa, only to discover her preserved body in a glass coffin. What follows is a "terrifying path of revenge," according to snippets from Letterboxd and TMDB . The film leans into classic Thai horror tropes—vengeful spirits, infidelity, and supernatural retribution—but with a modern edge. MyDramaList tags it as a mix of thriller, horror, and supernatural elements, with a runtime of just 92 minutes, suggesting a tight, no-frills scarefest
.
The cast is stacked with Thai industry veterans, including Woranuch Bhirombhakdi (The Medium, Pee Mak) as the likely spectral antagonist, and Thanavate Siriwattanakul as the unfaithful husband. Arachaporn Pokinpakorn, who plays the mistress, is no stranger to morally ambiguous roles, and her chemistry with the rest of the ensemble could make or break the film’s tension .
Vathanyu Ingkawiwat, the director, is keeping details under wraps, but the film’s premise suggests a deliberate nod to Thai folklore, where the dead are often portrayed as active, vengeful forces. The glass coffin—a striking visual—hints at a story that blurs the line between life and death, a theme Ingkawiwat may be exploring with a fresh lens.
What’s less clear is how the production handled the darker elements of the story. Thai horror films often walk a fine line between camp and genuine terror, and Tomb Watcher’s success may hinge on whether it leans into the supernatural dread or opts for a more melodramatic approach. Rumors (unconfirmed) suggest reshoots were needed to heighten the scares, but without official statements, it’s hard to separate fact from speculation .
Thai horror has seen a resurgence in recent years, with films like The Medium and Long Live the Bride proving there’s an appetite for supernatural thrillers. Tomb Watcher’s premise—infidelity, wealth, and a ghostly reckoning—feels like a natural evolution of the genre, blending social commentary with jump scares.
The cast’s experience in horror is a major plus. Woranuch Bhirombhakdi, in particular, has a knack for playing eerie, otherworldly characters, and her involvement could elevate the film beyond typical ghost-story fare. If the trailer (not yet released) delivers even half the unease promised by the synopsis, Tomb Watcher might just become a sleeper hit .
For all the buzz, details remain scarce. There’s no word on the film’s budget, shooting locations, or whether it’ll get a theatrical release outside Thailand. The lack of a trailer or official poster suggests the marketing push is still in its early stages, leaving fans to speculate based on snippets alone.
One thing’s certain: Tomb Watcher isn’t just another ghost story. With its mix of betrayal, revenge, and supernatural horror, it’s positioning itself as a must-watch for fans of Thai cinema—and a potential breakout for director Ingkawiwat.
