Mumbai, Apr 15 (IANS): Bengali actor Saswata Chatterjee's assassin character Bob Biswas from Sujoy Ghosh's "Kahaani" is said to be heading for the small screen.

"The idea is being worked on. But it isn't easy. Bob (Saswata) would have to relocate from Kolkata to Mumbai. That uprooting may not be easy for him since he has lived in Kolkata all his life. That's where his roots, family and career are," said Ghosh.

Ghosh is intrigued to see the kind of popularity the character has garnered in a short span of time.

"Bob's character is on screen for barely 5-7 minutes. But audiences have adopted him. I get suggestions on how to take Bob's character forward from youngsters on the net. There's a Bob Fan Club in Kolkata that is constantly churning out ideas.

"I think people like his ordinariness. Bob isn't your suave gun-toting, cool killer. He is an overweight job holder. We didn't give Bob a family life. But he probably goes back to a family after killing. He probably needs a second income to support his family. That's why he does the killings. I don't know. These are the details from Bob Biswas' life that need to be fleshed out. And we're working on it," Ghosh added.

However, Saswata seems to be apprehensive about his character being taken forward.

"The only problem with a television serial is, you never know where it would go. Suppose tomorrow they decide to make Bob into this pathos-laden victim of circumstances, who goes home to his ailing mother after the killings, it would be rather sad for the character. I'd like Bob to be taken further only if the material justifies his renewal," he said.

Saswata, who's the son of distinguished Bengali actor Subhendu Chatterjee, says if the need arises, he can shuttle between Kolkata and Mumbai.

"I've my entire life in Kolkata. My nine-year-old daughter Hiya studies here. My wife Mohua is a teacher. I can't wrench them out of their environment. But I can easily travel between Kolkata and Mumbai," said the actor.
