¡Que viva México! is a film project begun in 1930 by the Russian avant-garde director Sergei Eisenstein (1898–1948) under contract to socialist author Upton Sinclair and other supporters in the United States. It would have been an episodic portrayal of Mexican culture and politics from pre-Conquest civilization to the Mexican Revolution. Production was beset by difficulties and was eventually abandoned. Jay Leyda and Zina Voynow call it Eisentein's "greatest film plan and his greatest personal tragedy".
