"She is a thinking man's heroine and she is beauty with brains. I have always looked up to the attitude and the personality that Sushmita has exuded," Mukherji said.

"Nirbaak" (Speechless) is Sushmita's debut in Bengali cinema. The film also stars Jisshu Sengupta, actor-director Anjan Dutt and Ritwick Chakraborty.

It releases on May 1 and its trailer has garnered more than 100,000 views since its release earlier this month.

"My story needed that kind of a woman...a woman of substance. I believe in out-of-the-box storytelling, so naturally the cast also will be unconventional," added Mukherji.
