Grandfather of left-wing propaganda films
Lenin was impressed. This film, more than any other, made him aware of cinema's potential as a medium for the masses and gave Eisenstein the political support he needed to proceed with his Battleship Potemkin. Eisenstein, in turn, profoundly influenced leftist radicals like Che Guevara and Franz Fanon.
So you could say that, unwittingly, DW Griffith was the grandfather of left-wing propaganda films.
