Nøglehullet (1974)

Mette & Soren are young lovers. Mette's father hires Soren (not knowing he is his daughter's boyfriend) to write a script for a 'realistic' porn movie. Soren discusses this with Mette, arguing that if realistic it would be boring as it would be about ordinary people. Mette convinces him that ordinary people don't have boring sex lives - her family and their friends for instance. She spies on her father, his business partner and her mother, and gets a job in a massage parlor for research. Soren photographs two girls and a guy in a porn shoot. Mette and Soren also spend a lot of time together while Soren works on the script. When Soren presents the finished script, it is rejected as 'too unbelievable' by the very people it is about.
