Second attempt to create a feature film out of the 200,000-plus feet of film which Soviet film-maker Sergei Eisenstein shot during 1931-32 in Mexico for American socialist author Upton Sinclair, his wife and a small company of investors. The projected film, to be called "Que Viva Mexico", was never completed due to exhaustion of funds and Stalin's demand that Eisenstein return to the USSR (he had been absent since 1929). The first attempt at editing the footage, in the USA, resulted in "Thunder Over Mexico", released in 1934. In 1940, Marie Seton, from the UK, acquired some of the footage from the Sinclairs in an attempt to make a better cutting according to Eisenstein's skeletal outline for the proposed film. This film has apparently been lost.
