It was earlier announced that director Gautham Menon will be playing an important role in Sibiraj's Walter. Now, it has been revealed that the filmmaker has been replaced by cinematographer-actor Natty (a) Nataraj Subramaniam. 

The director of the film, Anubu clarifies that a clash of dates is the reason for Gautham opting out of the project. "Gautham Menon sir had to leave the project due to his directorial commitments. Now, we have replaced him with Natty, who has begun shooting for the film. He will be playing a character with grey shades."

The film, which is in the last leg of shooting, also stars Samuthirakani and Shirin Kanchwala of Nenjamundu Nermaiyundu Odu Raja fame.
