There are unconfirmed reports that the fifth installment of the CBI Diarykurippu series is being planned by the director K Madhu and writer S N Swami. The film would be produced by Madhus own production company, Krishnakripa Films. It is rumored that SN Swami has started working on this project. Though there have been several sequels in Hollywood, there has been no other film when the entire crew including the actor, director and the writer have joined hands for five installments of a film. So the fifth part of the film is expected to set a record.
