Cast, Story Outline, Crew, and Streaming Details

Directed by debutant Jithin K. Jose, who also co-wrote the screenplay along with Jishnu Sreekumar, Kalamkaval is produced by Mammootty Kampany. The film features Mammootty and Vinayakan in central roles, supported by a cast that includes Gibin Gopinath, Gayatri Arun, Rajisha Vijayan, and Shruti Ramachandran.

Set in early-2000s Kerala, the narrative follows Sub-Inspector Jayakrishnan as he begins investigating what initially appears to be a routine law-and-order issue linked to local unrest. As the inquiry progresses, patterns begin to emerge that point toward unresolved disappearances across rural regions near the Kerala-Tamil Nadu border. The investigation expands in scope, drawing in additional officers and exposing the complexities involved in tracking an organized and elusive operation. The film unfolds as a procedural drama focused on methodical investigation, uncertainty, and the strain placed on those involved in long-running cases.

On the technical side, Kalamkaval brings together an experienced crew. Cinematography is handled by Faisal Ali, while editing is by Praveen Prabhakar. The film's music is composed by Mujeeb Majeed, with sound design by Kishan Mohan. Production design is by Shajie Naduvil, and action sequences are choreographed by Action Santhosh.

With its OTT release, Kalamkaval is now accessible to audiences who either missed the film in theaters or prefer watching crime thrillers at home. SonyLIV remains the sole platform to stream the film online following its theatrical run.
