In keeping with his idea of Jesus Christ as the greatest revolutionary of all time, Pier Paolo Pasolini considered casting Jack Kerouac or Allen Ginsberg in the role. He changed his mind when he met Enrique Irazoqui, a Spanish student of literature, who has written a thesis about Pasolini's novel "Ragazzi di vita" and was very curious to meet him.
Pier Paolo Pasolini used non-professional actors and cast local peasants, shopkeepers, factory workers, and truck drivers. For Mary at the time of the Crucifixion, he cast his own mother Susanna Pasolini.
