Prosthetic penises are used in the sex scenes, except the one in which Federica Tommasi performs a fellatio on Andrea Nobili.
At the audition, Tinto Brass, after asking Raffaella Ponzo to undress completely in front of him, pointed to her breasts. "He said, 'Are those boobs real?' I replied, 'Sure, would you check...' And I have to say he checked in a very.... professional way, like a real doctor!" - Ponzo recalled.
The scene in which Virginia Barrett, while bathing, runs a foot over Raffaella Ponzo's body and puts it on her lips was conceived by the two actresses themselves. Ponzo said she is a foot fetishist in real life: "It's a passion that was passed on to me by Franco Saudelli, my partner, a fetish cartoonist and photographer. While we were shooting the scene in the bathroom, Brass said to me, 'Suck her big toe, otherwise what does Saudelli say?'"
Early in his career and confused about which path to take, Marco Bocci decided to audition for this film but he was passed over.
