Erwin C. Dietrich was involved in every aspect of film production, distribution, and exhibition. In certain stages of his career he was considered Europe's biggest film producer with an annual output of sometimes more than 10 films. From early on, Dietrich, a trained actor, recognized the potential of the "sexual revolution" of the seventies and started producing and directing erotic movies which were enjoying huge success at the box office. In his heydays, Dietrich employed some of Europe's finest exploitation directors such as Jesus Franco or Antonio Margheriti who were provided excellent working conditions, reasonable budgets and name actors. In the eighties the focus shifted to action movies such as Geheimcode: Wildgänse (1984) with Klaus Kinski and to Comedies such as Ein Schweizer namens Nötzli (1988). Dietrich also owns an independent film distribution company and movie theaters in Zurich, Switzerland.
