Churni said her debut film, which released recently, is centred around the solitary life of the author and her relation with her pet cat.
"The movie is in no way a biopic and is not intended to make a political statement either," Churni, an established actress in Bengali cinema, said.
The film, which won the best film award at the 2014 Delhi Film Festival and two National Awards (best Bengali film and sound designer trophy) earlier this year, features several poems written by Taslima as part of the background score.
She said that once when she and her husband, filmmaker Kaushik Ganguly, visited Taslima's house in Kolkata, they were struck by her motherly instinct as manifested in her relation with Minu, the cat.

Churni said Kaushik was so moved that he wrote a scipt about a mother and her child.
"When I took up the script, I tweaked it a bit and dwelt on the aspect of the author's loneliness and her love and care for the cat. It is more of an emotional drama," she insisted.
Taslima, who watched the film at her home, liked the concept and allowed some of her poems, which talked about a woman's solitude following social ostracisation, to be used in the film, Churni said.
