The National Film Archive of India (NFAI) has recently discovered 30 reels of unedited footage on Mahatma Gandhi that amounts to almost 6 hours of duration. These 35mm celluloid footages, unedited and stock shots with title cards in between, belonged to several prominent film studios of the time like Paramount, Pathe, Warner, Universal, British Movietone and Wadia Movietone. The major highlight of the discovery is a rare half-an-hour footage that has visuals of a special train carrying Mahatma Gandhi's ashes, after his assasination on 30th January 1948, from Madras to Rameshwaram. In 1964, the NFAI was established as a media unit of the Ministry of Information and Broadcasting (I&B) with headquarters at Pune, Maharashtra.
