Luis Buñuel has publicly stated that he considers the film a failure and that if he had shot it later in Paris, he would have gone more extreme with it (cannibalism).
The title was taken from a friend of Luis Buñuel, José Bergamín, who was writing a play with that title but never finished it. When Buñuel wanted to title his film, he asked for the rights of the title from his friend, but he answered that there was no trouble, because it was taken from the Bible, the Book of Revelation.
Luis Buñuel expressed frustration in regards to the film's low budget and the lack of amenities available on set in Mexico. As an example of these hardships, Buñuel recalled that the film operated on such an austere budget that he could not even afford to purchase fine table napkins for the dinner party scenes, nor could such napkins be easily obtained in Mexico at the time. He was only able to procure one such cloth napkin for a close-up shot of the dinner table when the film's makeup artist brought one from her home.
Was banned in Russia because the idea of people not being allowed to "leave a party" was considered offensive and anti-government.
Luis Buñuel has claimed the film contains over twenty pieces of repetition in it. The film actually contains 27 instances of repetition.
