"The Kashmir Files", which released countrywide on March 11, depicted the exodus of the Kashmiri Pandits from the Kashmir Valley in the 1990s.
It featured Anupam Kher, Pallavi Joshi, Mithun Chakraborty and Darshan Kumar.
Though the film was called out for its problematic politics by some critics and authors, it performed exceptionally well at the box office by minting over Rs 330 crore.
The movie also sparked a debate among political parties after several BJP-ruled states, including Madhya Pradesh, Uttar Pradesh and Gujarat, gave it exemption from entertainment tax.
Before "The Kashmir Files", the filmmaker directed "The Tashkent Files" based on the mysterious death of former prime minister Lal Bahadur Shastri in 1966.
His other film credits include "Chocolate" and erotic thrillers "Hate Story" and "Zid".
