Walerian Borowczyk revealed that Olivia Pascal was replaced by a double in the masturbation scene. "We did that later. The producer wanted me to do a very explicit scene, and he got it. The nun who does it, by the way, is a very beautiful German actress, Olivia Pascal. Well, we used a body double for those inserts. However, the sequence was filmed by me and Tovoli ! - Borowczyk said.
