This movie was made to help the director, Saenz de Heredia, recover from a terrible economic period, and except for Juanjo Menendez, all the stars who appeared did their work completely for free.
Due to a mistake, direction is attributed to Antonio Ozores in the film, but the real director is Mariano Ozores. Mariano confirmed it himself, and the name Mariano Ozores appears on the poster.
