Manjummel Boys (2024) Review – The Survival Thriller That Became Malayalam Cinema’s Biggest Hit

★★★★☆ Our Rating: 8/10

Most survival films invent their danger. Manjummel Boys does not need to. Released on 22 February 2024, Chidambaram’s Malayalam thriller retells a real incident from 2006 in which a cheerful holiday to Kodaikanal ended with a young man trapped deep inside a cave system that locals fear and authorities had fenced off for good reason. That true-story foundation hangs over every frame, and it is a large part of why audiences could not look away.

The film went on to earn around ₹242 crore worldwide on a modest budget, becoming the highest-grossing Malayalam film of its time. But money is only half the story. Does it actually work as cinema, or did curiosity about a famous rescue do all the heavy lifting? In this review we look at the story, the ensemble, the craft and the flaws, honestly and without spoilers about the outcome.

Quick Facts: Manjummel Boys at a Glance

The Story: A Laugh, a Shortcut, and Then Silence (Spoiler-Free)

The film opens in Kochi with a group of close friends linked to an arts club in Manjummel. They are loud, broke in the way young men often are, and held together by years of shared jokes and small loyalties. For the Onam break they pile into vehicles and head to Kodaikanal in Tamil Nadu, chasing the simple pleasures of a road trip — good food, cold hill air, photographs, and the kind of singing that only sounds good to the people inside the car.

Near the end of the trip someone suggests a detour to the Guna Caves, a forest cave formation made famous by an older Tamil film. A local guide warns them plainly that the restricted section is dangerous and off limits. The warning is heard, smiled at, and ignored. Slipping past the barriers feels like a harmless bit of daring, the sort of story they expect to laugh about on the drive home. Inside, they carve their group name on a rock and arrange themselves for a photograph.

Then one of them, Subhash, steps forward to join the frame — and the ground simply takes him. He drops into a deep, narrow fissure where daylight barely reaches and a voice can barely carry. What follows is not a creature feature or a puzzle-box mystery. It is something harder to watch: ordinary young men realising that friendship now means ropes, mud, rain, reluctant officials, and a decision about who, if anyone, will go down into that darkness after their friend. We will not tell you how it ends. The film earns its tension by making you sit inside that question.

Performances: An Ensemble With No Passengers

Soubin Shahir as Siju David, called Kuttan by the group, gives the film its moral spine. Shahir has built a career on seeming ordinary until the moment ordinary will not do, and here he plays a man whose courage is not loud. Watch how his face changes when he understands what the rescue will demand of him. He does not deliver a hero speech. He ties a rope, argues with fear in private, and acts anyway. It is the best kind of leading performance — one that makes everyone around him look more real.

Sreenath Bhasi as Subhash has the hardest technical job in the film. For long stretches he is a voice, a hand, a patch of torchlight, a man trying not to panic in a space the audience can barely see. That limitation could have turned him into a prop. Instead Bhasi keeps Subhash specific — frightened, embarrassed, exhausted, still trying to answer his friends so they will not give up on him. You never forget there is a person down there, not just a problem to solve.

Balu Varghese, Ganapathi S. Poduval, Lal Jr. and Deepak Parambol, along with the rest of the group including Abhiram Radhakrishnan, Arun Kurian, Khalid Rahman and Chandu Salim Kumar, succeed because they do not all play the same note of panic. One jokes to keep his hands steady. One wants to call for official help immediately. One blames himself. One freezes. The film understands that in a real emergency, a group of friends splits into different fears before it comes back together, and the casting honours that truth. Nobody is doing star turns. That is exactly why it works.

Direction and Technical Brilliance

Chidambaram, whose earlier work showed a sharp eye for group dynamics, directs this as two films stitched together with intent. The first portion is warm, loose and funny, shot like a memory you would want to keep. The second is cramped, wet and procedural. The contrast is the point: the audience must love the carelessness a little before it can feel the cost of it.

The cave itself deserves special mention. Production designer Ajayan Chalissery and his team built the cave environment as a practical set rather than leaning entirely on digital effects, and cinematographer Shyju Khalid shoots it with a discipline that keeps geography clear even in near-darkness. You always sense depth — how far down is down — without the film needing to explain it. The editing by Vivek Harshan is patient during the rescue and restless during the fall’s aftermath, which is the right way round. Where the film stumbles slightly is in its flashback structure and in a few expository passages about the caves’ history; they inform, but they briefly cool the urgency the present-tense scenes work so hard to build.

Sound design is quietly superb. Dripping water, rope strain, distant shouting and the horrible small sounds of shifting stone do more for dread than any jump scare could.

Music and Background Score

Sushin Shyam’s score knows when to disappear. During the holiday stretch the music is light and companionable, letting the group’s own noise carry the scenes. Once the accident happens, the score turns low, percussive and anxious, rising in the rescue passages without ever telling you that triumph is guaranteed. The film also makes affectionate, plot-relevant use of a beloved song associated with the older film that made these caves famous for tourists. It is not decoration — it becomes an emotional thread between the trapped man and the friends above him, and its return late in the film lands with genuine force. If anything, one could argue the score leans a little hard on swelling emotion in the final stretch, but by then most viewers will not mind.

What Works and What Doesn’t

What we loved:

• A rescue story built on friendship rather than spectacle or villains
• Soubin Shahir’s restrained, deeply believable central performance
• Practical cave sets and disciplined cinematography that make depth feel terrifying
• A first half full of genuine warmth that makes the second half hurt

What could be better:

• The opening takes its time; viewers expecting instant danger may find the holiday stretch slow
• A few flashbacks and history lessons interrupt the rescue’s momentum
• Some friends in the large ensemble get far less definition than others

Box Office: A Small Film That Outran the Industry

Made for a reported ₹20 crore, Manjummel Boys collected roughly ₹241–242 crore worldwide — sources differ slightly in their final tallies, with figures of ₹241.03 crore, ₹241.56 crore and ₹242.3 crore all reported, but every credible count agrees on the scale of the achievement. It became the highest-grossing Malayalam film ever at the time of its run, an extraordinary result for a film with no conventional star hero, no romance track and no action set pieces in the usual sense. It also travelled unusually well, drawing large audiences in Tamil Nadu, where much of the story is set, and performing strongly overseas. Its later dubbed versions widened that reach further. For a survival drama carried by an ensemble, this was a genuine industry moment.

Verdict: Should You Watch It?

Yes — especially if you believe tension comes from caring about people rather than from bigger explosions. Manjummel Boys is not flawless. It starts slowly, and its structure occasionally explains when it should simply show. But its heart is in the right place, its central rescue is staged with rare patience and realism, and its portrait of friendship under pressure feels earned rather than sentimental. It reminds you that heroism, in real life, usually looks like one frightened person refusing to leave.

Our rating: 8/10 — a gripping, humane survival thriller and a landmark for Malayalam cinema.
