Víctor Manuel Mendoza as Don Rodrigo, the local god-father, a typical bullying macho.
Michèle Cordoue as Anna, Don Rodrigo's harsh and vulgar French wife.
André Toffel as Tom, a French tourist stopping to die of meningitis in Alvarado
Arturo Soto Rangel as the local priest.
Luis Buñuel as one of Don Rodrigo's gun-bearers. The realistic-satirical description of the plague, along with numerous local spicy private jokes in the abundant Spanish part of the dialogue certainly owes a lot to the guest-star's presence.
