When the Gods Fall Asleep (Portuguese: Quando os Deuses Adormecem) is a 1972 Brazilian film directed by José Mojica Marins. Marins is best known for the Zé do Caixão (Coffin Joe) film series. The film is a sequel to Marins' 1971 film The End of Man (Finis Hominis), in which the character of Finis Hominis, an influential, messianic culture figure turns out to be an escaped mental patient. Rather than the horror themes which Marins was noted for, the film, like its predecessor, is low budget black humored social satire.

In this film, Finis Hominis (after returning to the asylum) again feels the need to escape the asylum in order to put right the world's increasing social unrest that he sees in the news.
