The Kunchacko Boban-Lijomol Jose starrer Unmadham is set to make its digital premiere on Sony LIV from September 4, the makers announced on Monday. The psychological thriller hit theatres worldwide on July 31 and opened to mixed reviews.

Scripted by Shahi Kabir and directed by editor-turned-filmmaker Kiran Das, it marks the latter's directorial debut. The project reunited Kunchacko Boban and Shahi Kabir after Nayattu and Officer on Duty, both of which featured the actor as a police officer.

Unmadham follows a constable played by Kunchacko Boban who begins investigating an old case with supernatural undertones while dealing with a fragile family life. As he delves deeper into the case, the mystery intensifies, blurring the lines between reality and delusion. The film also stars Siddique, Sudheesh, Vishakh Nair, Sabu Mon, Kottayam Nazeer, Gokulan, Arun Cherukavil, Unni Lalu, Shaju Sreedhar, Krishnaprabha, Kiran Peethambaran, Vishnu, Raina Radhakrishnan, Sijoy Varghese and Vigneswar Suresh.

Produced by Kumar Mangat Pathak and Abhishek Pathak under Panorama Studios, Unmadham is presented by Gulshan Kumar and Bhushan Kumar under T-Series Films. On the technical front, the film has cinematography by Arjun Sethu and music by Mujeeb Majeed, with Kiran also in charge of editing.

An excerpt from the CE review of the film reads, "Kiran Das makes a confident debut as a filmmaker, especially in the way he keeps the tension simmering through the first half, extracts strong performances, and executes some bizarre dream sequences that play out like a supernatural thriller, even if they tend to overstay their welcome. The latter half, however, is particularly overstretched, including a stylised fight sequence that just doesn't align with the film's overall tone and mood."
