The Unmadham cast is led by Kunchacko Boban as Shelly, a police constable drawn into a disturbing old case. Lijomol Jose co-leads the Malayalam mystery thriller, while Siddique, Krishna Prabha, Sudheesh, Vishak Nair and Sabumon Abdusamad are among its principal supporting players.
Kunchacko Boban as Shelly
Kunchacko Boban plays Shelly, the only principal character whose name has been publicly attached to an actor. Shelly is a police constable who reopens a long-forgotten case and encounters a file that his colleagues would rather leave untouched.
The role places him at the centre of the film’s central question: is the danger surrounding the file supernatural, or is fear hiding a more grounded truth? The trailer keeps the answer out of reach, but it makes Shelly the audience’s way into the investigation.
Lijomol Jose
Lijomol Jose is the film’s co-lead and shares top billing with Kunchacko Boban. Her character name has not been announced, and the campaign has not provided a reliable public description of her role. The film marks the first screen pairing of the two actors.
Siddique
Siddique is part of the principal ensemble. His exact character name remains under wraps, so it is too early to label him as a police officer, suspect or family member based only on trailer shots.
Krishna Prabha, Sudheesh and Vishak Nair
Krishna Prabha, Sudheesh and Vishak Nair are all confirmed for Unmadham. None of their character names has been announced. Their presence gives the film an experienced Malayalam ensemble around its two leads without revealing where each person fits into the case.
Sabumon Abdusamad and Kiran Peethambaran
Sabumon Abdusamad and Kiran Peethambaran also appear in the credited cast. Their roles remain unnamed in the public billing.
The wider supporting cast
The supporting ensemble also includes Anshif DP, Jijoy Rajagopalan, Kottayam Nazeer, Arun Cherukavil, Raina Radhakrishnan, Shaju Sreedhar, Sijoy Varghese, Unni Lalu, Gokulan and Vigneshwar Suresh. The campaign has confirmed their involvement without publishing dependable actor-character pairings.
What the cast setup tells us about the film
Unmadham is built as an ensemble mystery rather than a two-person star vehicle. Shelly’s investigation moves through a police station and a wider community unsettled by the same file, giving the supporting cast room to carry different pieces of the mystery.
The film is written by Shahi Kabir and marks editor Kiran Das’s feature directing debut. For the confirmed theatrical date, trailer and current OTT status, see our Unmadham release-date guide.
