"I will start preparing for the film at the start of next year because we are going to start shooting of the film from middle of 2020," added the actress.
On December 3, Taapsee took to Instagram to wish Mithali Raj on her birthday with a series of pictures and a heartwarming message, along with which she made the formal announcement of the film.
Taapsee Pannu has lately been a part of several successful films such as "Badla", "Mission Mangal" and "Saand Ki Aankh", and she has been vocal in her demand that male and female actors should get equal pay.
Has her recent streak of success ensured a hike in her fee? "Yeah… With every successful film, producers are ready to give more," she replied.
There are media reports that Taapsee Pannu might be seen essaying a double role in the upcoming "Sia Jia", produced by filmmaker Sanjay Leela Bhansali.
Talking about the film, Taapsee said: "Let me first sign the film, and I will talk about it then. Otherwise, I feel scared to talk about it."
"Shabaash Mithu" is backed by Viacom18 Studios and directed by 'Raees' helmer Rahul Dholakia.
