The 1938 masterpiece by Sergei Eisenstein, music by Sergei Prokofiev. A prophecy about the German invasion. Wikipedia: “The film depicts the attempted invasion of Novgorod in the 13th century by Teutonic Knights of the Holy Roman Empire and their defeat by the Russian people, led by Prince Alexander, known popularly as Alexander Nevsky. It begins as the knights invade and conquer the city of Pskov with the help of the traitor Tverdilo and massacre its population. In the face of resistance by the boyars and merchants of Novgorod (urged on by the monk Ananias), Nevsky rallies the common people of Novgorod and in a decisive Battle of the Ice, on the surface of the frozen Lake Chudskoe.” The battle was on the 5th of April, 1242.
I am not sure how you can fight, let alone gallop on ice. But the shot with the vast sky is the genius innovation of Sergei Eisenstein, repeated numerous times in photos, film and art.
