About the film
Tsar to Lenin is a documentary and cinematic record of the Russian Revolution, produced by Herman Axelbank. It premiered on March 6, 1937, at the Filmarte Theatre on Fifty-Eighth Street in New York City. Pioneer American radical Max Eastman (1883-1969) narrates the film.
Because of its pro-Trotskyist position, the film was suppressed by the Stalinists of the American Communist Party and was only widely available in a shortened format in the Library of Congress until its re-release in 2012 by the Socialist Equality Party (US), who state that its predecessor, the Workers League, purchased the film from Axelbank in 1978 and organized showings of the film in the intervening period.
