The Motorcycle Diaries is a 2004 biographical coming-of-age road movie directed by Walter Salles from a screenplay by José Rivera, based on Che Guevara's 1995 memoir of the same name and Alberto Granado's memoir Che Guevara: The Making of a Revolutionary. The film recounts the 1952 expedition, initially by motorcycle, across South America by Guevara and Granado, observing the life of the impoverished indigenous peasantry. Through the trip both of them witness the social classes struggle in Latin America.
