In this movie Yordanka Ariosa has sex scenes with Maykol David Tortoló, who was only sixteen at the time of filming: "That was one of the hardest things I've ever had to do. I'm not so modest when it comes to undressing, but having rough, almost animal sex, additionally with a boy who is half my age , was very complicated," Ariosa said.
Agustí Villaronga revealed that in Maykol David Tortoló's nude scenes, his penis was digitally enlarged.
Maykol David Tortoló said he hadn't problems being nude and having sex scenes with Yordanka Ariosa, but he would be more comfortable being alone with her. "I felt strange in the first scenes in which we shot the first nudes, the sex scenes, with the film crew who have to be there watching, which is their job," he said. "So I imagined that Yordanka and I were alone having sex, and I believe that it helped me to get out of that shell. I had to forget that all those people were there, and get much deeper into the scene, into the character."
According to his official twitter account (TortoloMaykolKH), Maykol David Tortoló was born on 10 December, 1998, so he was only 16 during filming.
