Eisenstein, Sergei
1898-1948
Russian film director whose work includes the classics: Potemkin (1925); Alexander Newsky (1938), and Ivan the Terrible (1944).

In his early films Eisenstein used untrained actors and made the common people his hero. He is famous as a theorist introducing new methods in camera angle, cutting, and montage, a number of images placed side by side. (See a sample of a montage below)
