An excellent 1969 documentary, S. Raitburt’s The Kuleshov Effect, made about a year before Lev Kuleshov died, and interviewing him at length, both about his filmmaking and his far lengthier career as a teacher (including some fascinating remarks about Bertolt Brecht’s Galileo). Also interviewed is the father of Russian Formalism, Viktor Shklovsky, who worked with Kuleshov as a screenwriter on a Jack London adaptation, By the Law, in 1926.
