Mammootty’s Malayalam crime thriller Kalamkaval is back in focus after its strong theatrical run, with confirmation now in place about its digital release. The film, which marked one of the veteran actor’s most talked-about performances of 2025, is set to reach a wider audience through its upcoming OTT premiere. Here is everything known so far about when and where the film can be watched online, along with details on its cast, reception, and background.
Kalamkaval OTT release details
Sony LIV has officially announced that Kalamkaval will begin streaming on its platform in January 2026. While the platform has not revealed the exact release date yet, it has clearly stated that the crime thriller will arrive sometime during the month. The streaming service also confirmed that the film will be available in multiple audio languages, including Malayalam, Tamil, Telugu, and Hindi. The announcement was made through Sony LIV’s official channels, putting an end to speculation around the film’s OTT plans.
Along with the confirmation, the makers released a new teaser to mark the OTT update. The teaser focused on the film’s grim tone and central character, adding to the anticipation among fans who missed it in theatres or are planning a repeat watch at home.
Box office performance and audience response
Kalamkaval hit theatres on December 5, 2025, and went on to record a strong box office run. According to industry tracker Sacnilk, the film grossed over Rs 80 crore worldwide, making it Mammootty’s most successful theatrical release of the year. Despite being centered on a serial killer, the film received a U/A certificate and was noted for its controlled depiction of violence, which set it apart from several recent Malayalam thrillers.
Critical response was mixed but largely positive. ETimes, in its review, noted that Mammootty’s performance stood out due to its restrained and precise approach, while Vinayakan brought a tense and brooding energy to his role. The review also pointed out that while the performances elevated the film, the screenplay could have explored certain characters in greater depth.
Story, cast, and crew details
Directed by debutant Jithin K. Jose, Kalamkaval is set in early-2000s Kerala and follows a police investigation that begins as a routine case but gradually expands into a complex inter-state mystery. Mammootty plays a serial killer, while Vinayakan is seen as a police officer leading the probe. The supporting cast includes Rajisha Vijayan, Shruti Ramachandran, Gibin Gopinath, and Gayatri Arun.
The film is produced by Mammootty Kampany, with music composed by Mujeeb Majeed. Cinematography is handled by Faisal Ali, while Praveen Prabhakar is in charge of editing. Action sequences were choreographed by Action Santhosh, and the song “Nila Kayum Velicham” received a positive response from viewers.
Following Kalamkaval, Mammootty is gearing up for his next major project, Patriot, an action thriller directed by Mahesh Narayanan that also stars Mohanlal. Earlier this year, he was seen in Gautham Menon’s first Malayalam directorial venture, Dominic and the Ladies’ Purse, which is already streaming on OTT.
