Aparna Sen's upcoming film 'Sonata' has amazed the audience with its unique and fresh trailer. Starring Shabana Azmi, Lillet Dubey, and Sen herself, the film is all about the life, friendship, and psychology of three women. The actress-cum-filmmaker, who prefers to be only behind the screen and not to act in a movie directed by her, had to star the film as producers wouldn't find a better fit for the role. In the movie, Aparna Sen plays Aruna Chaturvedi, a professor from Uttar Pradesh. Interestingly, Shabana Azmi plays a Bengali woman in this venture.
