Saaz (1998)
Saaz is a Hindi movie produced and directed by Sai Paranjpye and released in 1998, starring Aruna Irani and Shabana Azmi in lead roles. The plot is allegedly based on the life of legendary singing sisters of Bollywood, Lata Mangeshkar and Asha Bhosle. In an interview after the release of the film Asha said, "Its not true at all. To have two women in long plaits, take a couple of incidents and exaggerate them into a 3-hour film is such a waste of time."
