Rarely has a journey into madness so convincingly and so brilliantly been filmed. Luis Buñuel's directing and the playing of the actors, Arturo de Córdova and Delia Garcés, are simply magnificent, as was his crew, with Gabriel Figueroa as primus inter pares.
The obsessions (jealousy, suspicion, greed) of the main character of the movie burst into plain paranoia in one of the most hilarious/dramatic sequences ever shot in the history of the motion picture. The end comes as a shock when the main character appears in a most unexpected disguise. Luis Buñuel used shocks (an eminent trick of the surrealists) time and again in many of his movies in order to derange and provoke the spectators.
Of course, the main intrigue of the movie is a variation on the age old male nightmare of raising unknowingly the offspring of other men.
This bright movie is a must see for all movie buffs.
