"Deepa is a task master but in the best possible way. I find her to be really good and hardworking with her actors and in every other aspect which she looks into before coming on the sets," Shahana said in an interview.
The actress, who plays Amina Sinai, mother to lead character Saleem Sinai, in the film, says it was a learning experience to work with Mehta.
"After that, I won't say she is a taskmaster in making you cry or giving you a bad time. She is very invested in her actor. So for an actor, she is a brilliant director to have.
"She really pushes you to bring out a deeper emotional connect with the character and that's really a great thing for an actor's growth," she added.
