Alexis Nativel revealed that the scene in the auditorium (where he's completely naked in front of a lot of people) was shot at the very end of their shoot week, so he had time to get used to the crew, the people, the atmosphere. "I was mentally ready, once I'm in the moment, I tell myself that I can't go back anyway. But I remember that at the beginning we shot this scene in shorts so that people could adapt a little bit and I tried to make the gallery laugh to relax everyone and put everyone at ease and gradually everyone was quiet," he recalled.
Alexis Nativel wasn't 18 yet during filming. "We had a lot of trouble finding a school that would accept to have a naked minor in their establishment," director Rony Tanios said. "It was very complicated, we had many refusals. We also had to find people who were open to the idea of the film, because otherwise, when they find out what's going on, they can immediately ask to stop the shooting, but in the end we managed."
