Seema Biswas acted as the heroine in Kishan Kartha's Amshini (Hindi) which entered the Indian Panorama Section of Filmotsav 1988. However the general belief is that Biswas debuted after Shekhar Kapur watched her perform in NSD Repertory Company, and offered her a role in Bandit Queen. Although she had earlier acted in Assamese cinema, this was her first big break into Hindi cinema, and she arrived with a bang. Rooted firmly in theatre, she refuses to be typecast, and has worked in a variety of films and character roles. She has also worked in a number of Marathi, Malayalam, and Tamil films. Some of her Marathi films are Bindhast, Dhyaas Parwa, and Lalbaug-Parel. She has been honoured with the Life Membership of International Film And Television Club of Asian Academy Of Film & Television by the director Sandeep Marwah. In 2014, Seema Biswas has been included in the prestigious five member jury board of 45th International Film Festival of India(IFFI) to be held from 20th to 30th November at Goa.
