For Isabelle Blais, accepting the lead role in this movie required a total surrender of self. A nakedness, literally and figuratively. At worst, a masked modesty. Isabelle Blais did not disappoint. Not without shyness and anguish. "The striptease scene was the worst of the shoot for me, but I don't really remember it," says Blais. Because to dive, I had to go into an unconscious state. I didn't have to think."
It is with Jean-Hugues Anglade that Isabelle Blais shot the most daring scenes in this film. "I had never met Jean-Hugues Anglade before Borderline. I only knew his films, including Betty Blue (1986), which I also saw again before the D-Day. We had dinner together the day before the shooting. And then the next day, hop, naked! We were playing the rawest scene in the movie, the one in the hotel. In this context, the only thing to do is to dive in, hoping that the person in front of you will respect you and not make inappropriate gestures. I was very lucky. Jean-Hugues is a very simple, kind, funny person, who, without being an exhibitionist, turns out to be very comfortable with nudity," Blais said.
