Kalamkaval Review: Mammootty's Chilling Thriller Explores Cyanide Mohan Case
Kalamkaval Review: Mammootty's Slow-Burn Thriller

Mammootty delivers another masterclass in restrained performance in the newly released investigative thriller 'Kalamkaval'. The film, which hit theatres on December 5, 2025, marks the directorial debut of Jithin K. Jose. With a runtime of 2 hours and 19 minutes, this Malayalam-language film delves into the dark, real-life-inspired world of a predator targeting unmarried women.

A Narrative Rooted in Disturbing Reality

The plot of Kalamkaval is not for the faint of heart. It draws inspiration from the infamous case of Cyanide Mohan, a serial killer who lured unmarried women with promises of love and marriage. Mammootty steps into this chilling role, portraying a character driven by a ritualistic compulsion. The narrative begins with Special Branch officer Jayakrishnan, played by Vinayakan, arriving to control a communal riot in northern Kerala. Known in police circles by the codename 'Nathu' (owl), Jayakrishnan is an officer famed for solving impossible cases.

What starts as a routine riot control operation quickly spirals into a complex investigation. Jayakrishnan discovers a sinister pattern behind the disappearance of numerous unmarried women seeking companionship. As digital footprints and call records are pieced together, a horrifying picture emerges, suggesting a single, elusive predator may be responsible for over two dozen cases.

A Slow-Burn Procedural with Atmospheric Dread

The investigation widens its scope with the entry of Stanly Das, an officer from Tamil Nadu, highlighting the cross-state nature of the crimes. However, director Jithin K. Jose deliberately avoids fast-paced action. Instead, he crafts a slow-burn, atmospheric thriller that relies on psychological tension and procedural detail. The film is built on long silences, a detached narrative tone, and occasional bursts of score, creating an experience akin to methodically flipping through a grim case file.

The core of the film is the psychological duel between the two leads. Mammootty's predator, calm and precise, is pitted against Vinayakan's brooding and relentless investigator. Their dynamic is framed by their chosen animal identities—the owl and the rat—both creatures of the shadows, operating in morally ambiguous terrain. This cat-and-mouse game is more cerebral than physical, focusing on the unraveling of a methodical mind.

Performances and Final Verdict

There is no doubt that Mammootty is the film's biggest strength. Following his nuanced role in 'Munnariyippu', he once again delivers a performance sharpened by chilling stillness and cold calculation. Vinayakan provides a formidable counterpoint with his intense and coiled presence, though the screenplay could have explored his character's depth further.

The film has drawn comparisons to slow-burn police procedurals like 'Dahaad' for its focus on missing women, investigative methodology, and the unsettling calm of its antagonist. While the compelling performances and atmospheric world-building are significant assets, the film's uneven momentum prevents it from reaching its full potential as a gripping crime drama. The pacing, while intentional, may test the patience of viewers seeking more conventional thriller beats.

In conclusion, 'Kalamkaval' is a film elevated by its lead actors and its commitment to a moody, psychological exploration of crime. It earns a 3.0 rating from both critics and early users. For audiences who appreciate atmospheric tension, strong performances, and a story inspired by true events, this Mammootty-starrer offers a distinctly unsettling cinematic experience.
