In 1973, Billian directed
hardcore short-length
loops for the Swedish company
Venus Film. When the ban on hardcore pornography was lifted in Germany, he started to direct numerous short-length hardcore films there. In 1975, he directed the first German full-length hardcore feature film,
Bienenstich im Liebesnest (soft version known as
Im Gasthaus zum scharfen Hirschen, also known as
Zimmermädchen machen es gern). In 1976, he directed
Josefine Mutzenbacher...wie sie wirklich war? 1. Teil (
Sensational Janine) about the early life of
Viennese courtesan Josephine Mutzenbacher. The film that had the title role played by
Patricia Rhomberg who also had an intimate relationship with Billian was his greatest success. During this period, Billian continued to shoot loops, a number of which attracted particular attention such as
Massagesalon Elvira that featured Anne Magle, the Danish porn sensation of the '70s.
Josefine Mutzenbacher...wie sie wirklich war? 1. Teil was conceived by Billian as the first part of a Josefine Mutzenbacher series but when the producer Gunter Otto of
Herzog refused to finance a second part, Billian took the money from the production company
Starlight and directed
Die Beichte der Josefine Mutzenbacher (Josephine) in 1979. However, Otto who held the rights for the title released
Josefine Mutzenbacher...wie sie wirklich war? 2. Teil (Professional Janine) in 1980. Both films were unable to reach the success of the 1976 film, particularly due to absence of Rhomberg and lack of continuity with the first film. In 1981 (
Aus dem Tagebuch der Josefine Mutzenbacher ), 1987 (
Die Liebesschule der Josefine Mutzenbacher ) & 1991 Billian directed three further Josefine Mutzenbacher titles. Gunter Otto made consecutive Josefine movies (
Josefine Mutzenbacher – Wie sie wirklich war: 3,4,5,6. Teil) from 1982 to 1984. In the 1990s, he directed porn videos, especially for the producer
Tabu of
Bochum, but these videos fell far from the quality of his work in the 1970s. ==Selected filmography==
