I really like this film and I bought a copy for my library. This film concerns the Battle on the Ice, the Battle of Lake Peipus in 1242, between the Teutonic Knights and native Russian forces under Alexander Nevsky. I cleaned up and reposted my article on the battle. Please view it at http://www.rateitall.com/i-840353-1242-peipus-lake-battle-on-the-ice.aspx
The film was made by Sergei Eisenstein in 1938 at the time of the greatest pre-war conflict between the USSR and Germany. That was just before the Stalin-Hitler pact.
The anti-German propaganda is a little thick.
