The fifth instalment of the investigative series directed by K Madhu and scripted by S N Swamy, also stars Renji Panicker, Sai Kumar, Jagathy Sreekumar, Soubin Shahir, Mukesh Ramesh Pisharadi, Anoop Menon, Dileesh Pothen, Ravi Kumar, Harish Raju, Edavela Babu and Sudev Nair, among others. Mammootty is donning the character of Sethurama Iyer after a gap of 16 years. The first CBI film, 'Oru CBI Diary Kurippu', was released in 1988 and it was immediately followed by a sequel, 'Jagratha', in 1989.

Mammootty's lead character Sethurama Iyer, a brilliant investigative officer, is one of his career-best characters. As both the movies were super hits, the makers, after a gap of 15 years, did the third part of the movie, 'Sethurama Iyer CBI' in 2004, and a fourth part, 'Nerariyan CBI', in 2005. However, the third and fourth were an average hit at the box-office.
