I suppose the fact that this movie was made during the dictatorship of General Franco, when Spain did not register on any international cultural radars, accounts for the fact that it remains relatively unknown. In my opinion, this is not only the best film ever made by a Spanish director, but one of the best European films ever, and a masterpiece of dark comedy. It is a powerful indictment of the death penalty anywhere, and the scene in which proud and retiring executioner Amadeo sticks prospective son-in-law José Luis' fingers in the lamp fixture, thereby giving him a mild electric shock, remains an all-time classic ("You think that's bad? That's only 125 volts! The Americans are worse, with their electric chairs...")
This movie is stronger, deeper and funnier than any recent comedies by the likes of Pedro Almodóvar and other Berlanga-influenced Spanish directors, due to the bleaker political reality against which it was made. There is more directorial talent involved and the performances are stronger, with the glorious José Isbert stealing the show as always.
Times have improved in Spain, and filmmakers may have more freedom, but nothing as corrosive as this has been made since.
