For many years (and still), published and unpublished reports have circulated that Buñuel had used a dead goat's eye, or that of a dead sheep, or of a dead donkey, or other animal, in the notorious eyeball-slicing scene. However, in an interview in 1975 or '76, Buñuel claimed that he had used a dead calf's eye. Through the use of intense lighting, and bleaching of the calf's skin, Buñuel attempted to make the furred face of the animal appear as human skin.
