October: Ten Days That Shook the World (1928) IMDb
It misrepresents the Bolshevik coup as being both more(!) violent and more popular than it really was, while dehumanizing the democrats. By the time it was made, Stalin was already in power, firmly on the track of tearing down almost everything positive about the takeover(s), hence Trotsky (already purged) was excised from the film. The interesting form does little to distract me from this historical position.
