I claim Sergei Eisenstein as an Oregon filmmaker because he based his Oktyabr (1928) on the work of John Reed, who was from Portland.
Sergei Eisenstein trained as a civil engineer. He left the Red Army to become a set and costume designer for the First Workers theater of the Proletcut in Moscow in 1920. His Battleship Potemkin (1925) and Oktyabr (1928) are silent masterpieces which illustrate his profoundly influential theories of film montage.
After seeing Battleship Potemkin, producer Samuel Goldwyn famously fired off a telegram telling Eisenstein he liked it very much, and that he like to do something similar with him, only starring Ronald Colman.
