IMDB description:
"This film is based on the book about Vasili Ivanovich Chapaev (1887 - 1919) who was in real life the Commander of the 25th Division of the Red Army. Chapaev is an uneducated peasant and a decorated hero in the World War I and later in the Russian Civil War, that followed the Russian revolution. This man of action is fighting on the side of the poor people. His troops consist of peasants, just like him. Unable to write, he can brilliantly demonstrate various battle tactics by moving potatoes on the table. He is street smart. He never lost a battle against the experienced Generals of the Tzar's Army. Written by Steve Shelokhonov"
"It was awarded the accolade "Best Foreign Film" by the US National Board of Review in 1935, and the Grand-Prix of the Paris World Fair in 1937.
In a 1978 poll of cinema critics the film was considered one of the best 100 films in history."

Oktyabr (1928)
"In documentary style, events in Petrograd are re-enacted from the end of the monarchy in February of 1917 to the end of the provisional government and the decrees of peace and of land in November of that year. Lenin returns in April. In July, counter-revolutionaries put down a spontaneous revolt, and Lenin's arrest is ordered. By late October, the Bolsheviks are ready to strike: ten days will shake the world. While the Mensheviks vacillate, an advance guard infiltrates the palace. Anatov-Oveyenko leads the attack and signs the proclamation dissolving the provisional government."

Lenin: The Train (TV 1988)
Overall a nice movie, but more biased in favor of the mensheviks than the rest.
