In a 2016 interview, Susanne Schulze (now Susanne Fienhold Sheen), talked about the casting and the filming of this movie when she was 11 years old. She remembered one day of filming in Ketzin/Havel in particular. "The Ketzin fire department was on set that day because they had to make it rain for a scene," she laughed. "And then it got serious. In front of the whole crew and the firefighters, I had to take off my bathrobe while jumping and ended up naked in the water - this was perhaps embarrassing for me then so close to puberty."
