Mammootty has returned to the big screen with 'Kalamkaval', a dark, psychologically charged crime thriller that hit theatres worldwide on December 5.

The film marks the actor’s comeback after a brief health-related break, and fans celebrated with packed morning shows across Kerala and overseas markets.

Directed by Jithin K Jose, 'Kalamkaval' dives deep into a complex police investigation set in Kottayikonam, where minor clues unravel into a disturbing trail of brutal crimes.

Mammootty, reportedly playing a character with shades of grey, has already set social media abuzz with speculation about whether he is the film’s hidden antagonist.

The ensemble features Vinayakan, Shruti Ramachandran, Rajisha Vijayan and Gibin Gopinath, all contributing to the film’s gripping narrative.

'Kalamkaval' OTT Release: When & Where to Watch

Even as the film continues its theatrical run, viewers are already looking for its OTT details. According to OTTplay, 'Kalamkaval'’s digital rights have been acquired by SonyLIV.

While the platform has not announced a streaming date yet, industry trends suggest the film is likely to arrive online around 40 days after its theatrical release. This window may extend if the crime thriller maintains strong box-office momentum.

Creative Team & Additional Buzz

The screenplay, co-written by Jithin K Jose and Jishnu Sreekumar, blends investigative realism with psychological tension, while Mujeeb Majeed’s background score heightens the film’s moody atmosphere.

'Kalamkaval' also gained extra attention due to rumours about Mammootty’s health. Speculation about a serious illness circulated online, but the star’s team dismissed the claims, confirming he had fully recovered before resuming work.

There has also been chatter suggesting the film might draw loose inspiration from the crimes of Cyanide Mohan—though the filmmakers have not confirmed any such connection.

With strong curiosity surrounding its storyline and Mammootty’s intense performance, 'Kalamkaval' is poised to attract a large digital audience once it hits streaming.
