This was the first Argentine film to show full nudity.
Debut of actress Isabel Sarli and first career nude scenes. She was a model who was discovered by filmmaker Armando Bo when he spotted a series of ads with her photos. He cast her in this film and she appeared in most of his following films. They also became lovers after he divorced his wife. Her several nude scenes were highly criticized and condemned in Argentina. In spite of censorship and persecution, she became an international star and sex symbol, filming in Brazil, Uruguay, Paraguay, Mexico, Panama and Venezuela.
After casting first-time actress and former Miss Argentina Isabel Sarli, director Armando Bo took her to see an Ingmar Bergman film that included a nude scene and told her he wanted to do something similar by having her skinny dip in a pond. She was shocked and refused. But she finally agreed after he promised she could wear a nude-colored swimsuit. Yet on the day of filming the scene in the middle of the Paraguayan jungle, Bo told her they forgot the swimsuit. She was angry, but he managed to talk her into swimming fully nude by telling her no one would notice that she was naked because they would film from a great distance up on a hill. But, without her knowing, he filmed her with a telephoto lens that captured even the smallest detail of her naked body. When Sarli saw the film at the premiere with a theater of people, she was enraged and embarrassed. She confronted Bo the next day but he calmed her down by convincing her it would help make the film a success and her a big star. He even talked her into posing for nude promotional photos for men's magazines. Sarli went on to perform nude in most of the films she made for Bo during her career.
Director Armando Bo and actress Isabel Sarli worked together through most of her career and became lovers.
Censorship in Argentina delayed the film's release. In Paraguay, they didn't want to release it because General Stroessner, who was in charge of the government at the time, said that human exploitation would not occur in his country. We had to add a legend, at the beginning of the film, stating that human exploitation was part of Paraguay's past.
