However, the versatile actress, 49, who has been in the industry for over 20 years, feels that in India, an actress receives a lot of mother's role after crossing 30.
"I feel like a much more mature actor with a range of roles and performances that I did. But if in India you are older, as a female actor, post 30 you begin worrying. You begin to get only mother's role," Biswas told PTI.
"But recently we have seen different realistic stories. I am not worried but hopeful that different films will come my way. As an actor, I don't have too many worries as I keep myself busy with theatre projects also," she said.
"I have learnt from watching my own performances. I continue to change and improve as an actor, to achieve good quality acting. I also learn from my co-actors, their freshness, spontaneity and so on are inspiring," she said.
Though she has delivered memorable performances in various films, but one film of hers which no one can forget is 'Bandit Queen'. Despite doing several strong roles, people still remember her as 'Bandit Queen' and Biswas is fine with it and feels proud of it.
"I feel proud of the role... That role will always be with me. It was the first film which at that time was ahead of its time. For me it was my first and last film, but then I got many more offers after the industry saw my performance," Biswas said.
