Srijit said: "It's a film called 'Nirbaak' (speechless). It compresses together four love stories connected by the theme of silence. The stories are intertwined and connected by Sushmita's character."
Besides Sushmita, who features in all four stories, "Nirbaak" stars Jisshu Sengupta and Ritwick Chakraborty.
Sushmita has been wanting to do a Bengali film for a very long time.
She did a Bengali film, Mahesh Manjrekar's "It Was Raining That Night" in 2005, a remake of the director's "Astitva", but it never got released.
More recently, Sushmita was all set to star in Rupali Chatterjee's "Jodi Emon Hoto". That project is now as good as shelved.
