Wolf C. Hartwig (born September 8, 1919,Düsseldorf, Germany), sometimes credited as Wolfgang C. Hartwig and Wolfgang Hartwig, is a German film producer working in exploitation genres.
After acting as a film distributor, Hartwig's first film as a producer was the then controversial documentary Bis fünf nach zwölf – Adolf Hitler und das 3. Reich (1953). Seeing the value of notorious publicity, Hartwig began producing a series of exploitation films called "Sittenfilme" or "vice films" for his film production company Rapid Films. His first 15 films from 1957 to 1962 were economically based on original screenplays and did not use a major distributor.
Hartwig began the next phase of his career in 1962 with Hong Kong Hot Harbor. Hartwig not only found it cheaper to film in Near Eastern and Oriental locations but his films received international co-production funding from other European nations. His films were released by two major German film companies Gloria Film and Constantin Film, who were attracted by Hartwig's subjects of adventure, Eurospy films and works by popular German authors such as a film based on the adventures of the pre-World War II pulp fiction hero Rolf Torring that was reprinted in paperback after the war, and Westerns based on the works of Friedrich Gerstäcker.
In the late 1960s Hartwig moved to sex films such as the Schulmädchen-Report film series that initiated the Sex report film genre.
In 1977 Hartwig decided to film a large budget World War II film shot in Yugoslavia from the German point of view and engaged Sam Peckinpah to direct Cross of Iron. The film lead to a sequel Breakthrough (1979) directed by Andrew V. MacLaglen. His last film was Palace directed by Édouard Molinaro.
