La planche du diable

In a 2018 interview, star Elizabeth Lambert talked about shooting the nude scenes: "I was a bit nervous because [it] being an R-rated film, I knew that there would be a few nude scenes, which are never fun for me, and even though it wasn't my first rodeo, I still dreaded them. I think it's always a little harder for the woman because usually it's a male director with the male DP and most of the crew is male! You're lucky if you have maybe one or two females around... Of course, they made it a closed set, very few people, only the essentials that were necessary: either holding a light or a boom but no stragglers. And believe me, I always make sure there are no creepers hanging around just to watch! Cuz they do!"
