There were reports that she has been signed for the film, but the "Baby" star says she is yet to read the script.
"I have been asked, but we are figuring out time when will I go and listen to the script because I've been running around with these things (promotions). Once 'Pink' releases, I'll hear it and then see," Taapsee said in an interview.
Manipur's 'Iron Lady' Irom Sharmila had last month broken her 16-year-old hunger strike, the world's longest, and declared that she wants to become the chief minister so that she could repeal the contentious Armed Forces Special Powers Act (AFSPA).
During her fast, the 44-year-old rights activist was force-fed through a nasal tube to keep her alive at a government hospital, a room of which was turned into a jail for her.

She was also granted bail by a court in Imphal after she promised the magistrate to break her fast against AFSPA.
Taapsee says it is a big responsibility to take on the role of Irom Sharmila as she may face some backlash too.
Taapsee is currently awaiting the release of her next film "Pink", also featuring megastar Amitabh Bachchan.
The drama-thriler, directed by Aniruddha Roy Chowdhury and produced by Rashmi Sharma and Shoojit Sircar, is scheduled to release on September 16.
