In reference to the lesbian scene with Christiane Paul, Maria Ehrich said to BILD: "I had never kissed a woman before. For Christiane Paul and me, it was the first time. I wasn't shy. On the contrary. I think when two women shoot a love scene, it's even easier than with a man and a woman. Two women among themselves know better how it should look and feel." (IMDb)
