Lara Wendel was only 13 during filming. In a 1979 interview at Italian magazine 'Oggi', she was asked if she was embarrassed doing her nude scenes, including the one where she masturbates in bed next to Franco Nero, who plays her father. "No, not at all. I often walk around the house naked even when my older brother is there. That other thing, then, I didn't do it but a stunt double," she said.
