Amar Lenin Bengali , subtitle My Lenin is a 1970 black and white documentary film directed by legendary film director Ritwik Ghatak made for Government of West Bengal in the centenary year 1970 of the birth of Vladimir Lenin.
After making the film, countries such as the Soviet Union and the Peoples Republic of Poland approached Ritwik Ghatak for him to show the movie in those countries. However, issues arose with the National Film Censorship Board of India which did not approve of the movie and banned it in India. Ghatak and his team had to work hard to have the movie passed by the censorship board. Ritwik Ghatak personally met with Indira Gandhi on this matter.
