The title refers to a party game, Cadavres Exquis (Exquisite Corpses) invented by the French Surrealists. Each person in turn would be handed a piece of paper folded accordion fashion so that only one narrow horizontal strip showed at a time. The person would draw a section of a human body but would not know what other people had previously drawn. At the end the paper would be unfolded to show the entire body, which would be a mixture of fat and thin, young and old, male and female, etc. The title therefore means that one is not able to use what happens as any guide to what will happen next.
Renato Salvatori and Marcel Bozzuffi played the thugs in the political conspiracy of Z, l'orgia del potere (1969).
