Communism, violent camerawork and surreal landscapes.

I am Cuba
"The movie's acrobatic tracking shots and idiosyncratic mise en scene prompted Hollywood directors like Martin Scorsese to begin a campaign to restore the movie in the early 1990s."

It's a shame that the Soviets didn't save a copy of the film in its original language. It might be the unfamiliarity with the Russian language, but contrasted with the overdubbed romantic sounds of my native tongue the unenthusiastic voice acting done by no more than two actors sounded harsh and only appropriate when the characters were angry. The film had a constant sense of visual surreality--most memorably in the apocalyptic scene featuring a recently disenfranchised farmer of Don Quixote quality burning his plantation and belongings in defiance towards the businessmen destroying his Cuba. The film explores the different levels of Cuban life which the film-makers perceived were being tainted through the proto-globalization of the time: morality, education, business... There were a few occasions in which native characters were depicted as a more civilized variation of the noble savage, but for the most part the film stayed away from caricaturing either side of the struggle of the valiant proletariat against the bloated bourgeoisie. 
Like many of their great works (I'm looking at you Upton Sinclair,) the film contains a pretty heavy anti-capitalist message.
