CBI 5: The Brain, the last installment of Megastar Mammootty's much-waited CBI series, is one of the most awaited movies of the actors' career. As the movie's shoot is progressing at a brisk pace, the makers of the movie have now unveiled a stunning poster that has the CBI team back in action. Interestingly, the new poster was unveiled through actor Jagaathy Sreekumar's official Facebook handle. “CBI 5. Coming soon," captioned the actor. The poster features the main CBI characters Sethurama Iyer (Mammootty), Chacko (Mukesh) and Vikram (Jagathy Sreekumar). As you know, the movie marks the comeback of veteran actor Jagathy in cinema. And naturally, fans are extremely excited to see the actor in the poster.

Take a look at the poster -

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.

It was last month, the makers had unveiled the title of the movie. 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, Kaniha, Aasha Sharath, Dileesh Pothen, Ravi Kumar, Harish Raju, Edavela Babu and Sudev Nair, among others. Apart from Jagathy, the actor's son Rajkumar Sreekumar will be also essaying a pivotal role in the fifth installment of the CBI series. Coming to the technicalities, the movie's music is by Jakes Bejoy and the cinematography is by Akhil George. A Sreekar Prasad is roped in as the editor for the movie.
