Srijit said, "It's a film called Nirbaak (speechless). It comprises of 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 Mahesh Manjrekar's It Was Raining That Night in 2005, a remake of the director's Astitva, but the film was never released.
More recently, Sushmita was to feature in Rupali Chatterjee's Jodi Emon Hoto, but the project has now been shelved.
