In the late 1930s, Hitler was menacing central and eastern Europe – and the Soviet Union, after initially attempting to appease him, was finally realising the scale of the threat posed by Nazi Germany. So how to get the Soviet public onside? Step forward brilliant movie director Sergei Eisenstein. In a film called Alexander Nevsky, he depicted the heroic struggle of the Russian medieval armies against the Teutonic knights. The Battle of the Ice still chills me to the bone – a fantastic piece of film making. The music is by the composer Prokoviev. Unfortunately, Stalin pulled the movie after he decided to enter into new negotiations with Hitler.
