While Che is idolised, the reality of his activism is often lost behind the icon. Dindo’s film gives substance to the legend. In 1961 Guevara became a minister in Castro’s government. In this capacity, in Algiers in 1965, he delivered a powerful speech indicting socialist powers for exploiting the Third World and, in effect, colluding with US imperialism. Soon he was to resign and leave Cuba forever. In 1966, with 16 comrades, he entered Bolivia to conduct a guerilla war but in less than a year later he would be dead, his wide-eyed corpse [and his diary] on display for the world to see.

Based on this very diary and the memories of those who met him, this moving portrait lends substance to the man on the T-shirt.
