The actor, known for his performances in 'Eagoler Chokh'and 'Dhanonjoy', said the digital medium gave him more freedom to experiment with the look and feel of the character.
"There is no need to maintain continuity between different episodes in a web series. You can reinvent yourself in every episode while sticking to some basic traits and characteristics which the role demands," he told PTI.
About his preparations, Bhattacharya said, "I have tried to project him as a crime-buster as well as an ordinary human. To think of it, the character has four to five sides to it and I tried portraying them all."
The actor also said that he made his preparations without thinking too much about others who had donned the dhoti-clad detective's hat in the past.
