While taking to mediapersons, Kiran shared that biopics are successful these days because they are interesting to watch. Expressing about her wish to make a biopic, Kiran said that she was thinking to make a biopic on the life of Gauhar Jaan. She added that her life will be interesting to watch as very few people know about her. Gauhar Jaan was an Indian singer and dancer (or tawaif) from Calcutta. She was one of the first performers to record music on 78 rpm records in India, and released by Gramophone Company of India.
