Thandakaaranyam Tamil Movie Review: A Tale of Struggles and Survival

Thandakaaranyam, written and directed by Athiyan Athirai, is a raw and intense drama produced by Pa. Ranjith along with Sai Devanand S and Sai Venkateswaran under Neelam Productions and Learn and Teach Production Private Limited. The film was released on September 19, 2025, with music composed by Justin Prabhakaran. Featuring Kalaiyarasan and Dinesh in the lead roles, with Riythvika and Shabeer Kallarakkal playing supporting parts, the movie dives into caste oppression, survival struggles, and the unending fight for dignity. With cinematography by Pratheep Kaliraja and editing by Selva RK, the film is shaped as a powerful narrative of pain and perseverance.

Kalaiyarasan plays Murugan, a determined young man from a lower-caste community who dreams of becoming a government employee. Murugan’s life takes a painful turn when he speaks the truth against his higher officer during training, which leads to his rejection and wastes seven long years of his preparation. This heartbreak is only the beginning of Murugan’s struggle, as the brothers continue to fight against a system that suppresses them.

His elder brother Sadaiyan, played by Dinesh, sacrifices his own land to support Murugan’s ambitions.
The narrative shifts when Murugan is enrolled in a military academy at Jamshedpur after his brother’s sacrifice. A new scheme is announced where some trainees must accept being labeled as Naxalites in front of the media, after which they undergo brutal training with the promise of being absorbed into the army. Murugan, along with other selected men, accepts the challenge. What follows is a harsh and painful journey where they are treated mercilessly, and the question remains whether Murugan and his fellow men survive this ordeal, and what becomes of Sadaiyan. The film builds suspense around this emotional and political drama.

Kalaiyarasan delivers an intense performance as Murugan, bringing depth to the character’s silent pain and determination. Coming from his earlier fun entertainer Trending, this role is a major step forward in his career, showing his maturity as an actor. Dinesh, on the other hand, after his appearance in Rubber Band, has taken up a matured and layered character as Sadaiyan. His performance is heartfelt and elevates the emotional quotient of the film. Riythvika and Shabeer provide strong support, and though their roles are limited, they add weight to the story.

On the technical side, director Athiyan Athirai keeps the narration grounded and powerful, never losing grip on the core issues of caste discrimination and survival. The involvement of Pa. Ranjith is clearly visible in the theme, as he is known for backing socially conscious stories. Justin Prabhakaran’s music gives life to the film, balancing the harshness of the subject with emotional depth. Pratheep Kaliraja’s cinematography captures the forest landscapes and training grounds with authenticity, while Selva RK’s editing keeps the pace tight despite the heavy subject. Together, the technicians have built a strong backbone for the film.

Overall, Thandakaaranyam is not just a story of two brothers, but a mirror to the struggles faced by oppressed communities. It questions authority, highlights injustice, and portrays the sacrifices people are forced to make in pursuit of dignity and survival. While the subject is heavy, the film stands out for its honesty, performances, and technical finesse. For Kalaiyarasan and Dinesh, it marks an important milestone in their careers, proving their ability to handle challenging roles. Thandakaaranyam is a bold step in Tamil cinema, shedding light on dark realities with sensitivity and strength.

Final Verdict: (4/5)
Thandakaaranyam is a hard-hitting film with strong performances and a socially relevant theme. A must-watch for those who appreciate of speaking cinema.
