Soundtrack
Modern prints of the film feature a soundtrack consisting of excerpts from Richard Wagner's "Liebestod," the concert version of the finale to his opera "Tristan und Isolde," and a recording of a tango sometimes mistakenly referred to as "Olé guapa." This is the same soundtrack that Buñuel chose and played live on a phonograph during the original 1929 screening in Paris. They were first added to a print of the film in 1960 under Buñuel's supervision.
