Behind the scenes
When Nils Malmros called Gitte Iben Andersen and told her that she had become the chosen one, she noticed that there was also a nudity scene. She was therefore refusing - but nevertheless said yes, when the film director added in a slight way that all other girls had said yes - without knowing that he had used the same trick towards the other girls.
