Recalling the filming of this movie, Katja Bienert said, "This was an outstanding experience, cause the stuff was already cult when we worked on No 13: All the later well-known actors denied later on in their careers that they worked in those reports that were based on real schoolgirls' (and -boys') experiences: Compared to nowadays charming, stupid and harmless. I enjoyed working with the production and playing a Greek schoolgirl with a religious background and her own thoughts on strict virginity was fun. I looked great in those days and I remember whenever I had to shoot a love scene the producer Wolf C.Hartwig showed up on the set"
Despite her two full nude scenes and fully developed body, actress Katja Bienert (DoB 09.01.66) was either 12 or 13 when filming and only 13 when the film was released.
One of at least two films promoted in the United States with advertising and posters showing the title as "Making Out" and identifying the lead actresses as Jessie St. Clair, Nona Phillips, Sandra Gayle, and Brigette Lee, none of which are the names of cast members in this film. Another film released with the same advertising campaign and posters was Excitation au soleil (1978).
