Entre mayo y diciembre de 1946, después de un grave ataque cardiaco, y a sugerencia de Prokofiev, Eisenstein empieza a escribir sus Memorias. Las llama "inmortales" porque no se proponen demostrar ni explicar nada. Son un "vagabundeo" por su vida. El resultado es un libro apasionante que es difícil dejar de las manos y en el que aparecen países, personas, sucesos con una vitalidad y un talento asombrosos.
Sergei Mikhailovich Eisenstein was a Soviet film director and film theorist, a pioneer in the theory and practice of montage. He is noted in particular for his silent films Strike (1925), Battleship Potemkin (1925) and October (1928), as well as the historical epics Alexander Nevsky (1938) and Ivan the Terrible (1944, 1958). In its 2012 decennial poll, the magazine Sight & Sound named his Battleship Potemkin the 11th greatest movie of all time.
Eisenstein was among the earliest film theorists. He believed that editing could be used for more than just expounding a scene or moment, through a "linkage" of related images. He developed what he called "methods of montage": 1) Metric 2) Rhythmic 3) Tonal 4) Overtonal 5) Intellectual
Eisenstein's articles and books—particularly Film Form and The Film Sense—explain the significance of montage in detail. His writings and films have continued to have a major impact on subsequent filmmakers.
