There have been movies about Che Guevara, including a very bad right wing hit movie entitled “Che” in which Omar Sharif played Castro and was contractually forced to utter lines like “the revolutionary and the peasant are like the flower and the bee – neither can propogate without the other.”
There was a movie about Rosa Luxembourg. One about John Reed. Lenin has been depicted, including a very nuanced depiction in the old BBC series The Life of Reilly (the real life character upon which James Bond is loosely based). There was a sympathetic depiction of Trostky in Frida. But nothing, positive or negative, about Marx – not even by CP/fellow travellor movie makers cranking out agit prop films like Salt of the Earth or Burn!.
There have been plenty of depiction of Hitler. I can only think of one depiction of Stalin in Children of the Revolution. Oh, actually there was a depiction in The Life of Reilly – not so nuanced, but then he wasn’t very nuanced in real life.
Wikipedia has an entry re Marx in film, but it’s mostly documentary, though there’s apparently something which may be in the works - Haitian director Raoul Peck has apparently been working on a bio-film since 2007.
But whatever your views on the person, he is a fascinating character – much drama in his life – and for better or worse has had a profound impact on the whole planet and its course of history. Why the absence of treatment?
