Mar Flores revealed that, despite having a body double to bathe in Valsaín, with the water at about five degrees, she jumped in, and five times, "to give the film more quality".
In September 1997, the Spanish magazine "La Revista' (El Mundo) included Dafne Fernández, who in this film plays the puberty of the main character, in a report dedicated to the Lolita of Spanish cinema. Fernandez, who was 11 or 12 years old during filming, is given only about a minute and a half of screen time to illustrate Maria's childhood days, yet packed into that brief time she is given a fully nude bath scene that has a moment where she stands displaying her wet pubescent body at close range. Her genital cleft and undeveloped breasts are some of the few things that can be seen in full intimate detail at that time.
