She urged film industry members to come out in support of Bhansali and his film.
"The Padmavati controversy is not only unfortunate but also a calculated plan of a political party to destroy the freedom to express ourselves.
"We condemn this super emergency. All in the film industry must come together and protest in one voice," Banerjee said in a tweet.
The makers of "Padmavati" had yesterday deferred its release from the slated December 1 date, even as protests and threats over the period drama continued unabated.

The film has been facing controversy since Bhansali started its shooting earlier this year.
The director was roughed up by members of the fringe group Rajput Karni Sena in Jaipur. Its elaborate sets were also vandalised during shooting schedules in Jaipur and Kolhapur.
The first poster of the movie was released in October this year and triggered a storm with various Rajput groups and others alleging that the director had "distorted" historical facts.
