Final movie of Luis García Berlanga.
During a conversation, Gaby, the character played by Javier Gurruchaga, asks Michel if he has ever heard of Luis Buñuel and he answers that he has not. In real life, Michel Piccoli worked with Buñuel on several films.
Concha Velasco lobbied heavily for her role on the movie, as she wanted to work with Luis García Berlanga for years.
"I had to conquer Berlanga through his wife, María Jesús [Manrique]", she said. "It was she who told me that he liked the color fuchsia and that I had to put that color on me even on my pubic hair. I told my children that I wanted to work with Berlanga, but that the first thing he was going to ask me was to undress. And my children told me: 'With Berlanga, whatever!' So I went to the casting with my hair, nails and even pubic hair dyed fuchsia. I stripped completely and, since I knew Berlanga didn't like people who had plastic surgery, I told him, 'Touch, touch (my tits), they are hard as a rock!' Then I showed him my pussy and so he took me," Velasco recalled.
Joaquín Oristrell collaborated on the screenplay with Luis García-Berlanga for over a month.
Luis García Berlanga didn't like Concha Velasco's ass enough for the poster and put up Fedra Lorente's one instead. But the director later said that "The last breasts that look great are the ones I saw on Concha Velasco in the film Paris-Timbuktu, although here the ass was also beautiful. She is an artist who has worked with me a lot and I love her.
