CBI (film series)

Lore & Background

The series depicts a team of three CBI officers led by Sethurama Iyer investigating murder cases. All five released films feature Mammootty as Iyer, while the other two team members vary. Vikram, played by Jagathy Sreekumar, appears as a CBI officer in all five films but is not part of the three-man team in the third and fifth films, appearing only briefly. Chacko, played by Mukesh, appears in the first film but is not part of the team initially; he joins the team from the second film onward. Harry, played by Suresh Gopi, is part of the team in the first movie but is transferred to Madras in the second sequel.

Reader's Guide

The CBI film series holds significance in Malayalam cinema for popularizing the cerebral detective genre, with Sethurama Iyer becoming an iconic character. The character was inspired by police officer Radha Vinod Raju, who in 2009 became the first chief of India's National Investigation Agency. The series' legacy is built on its consistent focus on brain over brawn, as Iyer solves cases through intellect. A sixth film was announced by director K. Madhu, though writer S. N. Swamy expressed uncertainty about his participation. The franchise remains a benchmark for investigative storytelling in Indian regional cinema.
