La trastienda

The film is famous because it featured María José Cantudo in the first full frontal nude scene showing pubic hair in the history of Spanish cinema after the Ministry of Information and Tourism relaxed in February of that same year the prohibition of nudity in films, allowing it "according to the needs of the director." Reportedly, the nude scene wasn't in the script but once nudity restrictions were lifted, the director asked Cantudo to do it. She had been topless onscreen before but didn't want to go fully nude, but he finally talked her into it. He initially wanted to film her walking around nude in a longer scene, but she refused. So they compromised and just showed her briefly reflected in a mirror. Yet, she was incredibly embarrassed doing it. Even though she is only seen for a few seconds on screen, she had to spend considerable time fully nude on set in front of the all male crew while filming it, and the director made her shoot it several times.
