The Balcony (1963)

Shelley Winters is the madame of a house where customers play out their erotic fantasies, oblivious to a revolution which is sweeping the country. When her old friend, the chief of police (Peter Falk), asks her to impersonate the missing queen in order to reassure the people and halt the revolution, she offers instead three of her customers to play the general, bishop and chief justice, all of whom have died in the revolution.
