The story
Founded by Preben Philipsen and Waldfried Barthel on Apr 1, 1950, in Frankfurt.1
Constantin Filmverleih GmbH was founded in West Germany on 1 April 1950 by Preben Philipsen and Waldfried Barthel, who would later become the head of publicity for the company. It was originally the country's national distributor of films produced by Columbia Pictures and United Artists. Throughout the 1950s, Constantin distributed both popular and art-house films from several nations as well as medium-budgeted domestic films.
Constantin's popularity grew through the late 1950s to the 1960s by not only distributing popular films but creating its own in-house talent roster of contract players (Joachim Fuchsberger, Heinz Drache), directors and producers (Wolf C. Hartwig), as well as co-financing international co-production films shot in Italy, such as the Clint Eastwood spaghetti westerns, the films of Harry Alan Towers and others using their own stable of stars. Constantin also had great success with their Jerry Cotton film series, though projected film series of Sherlock Holmes, Jules Maigret and Perry Rhodan only had one entry.
Constantin Filmverleih was renamed to Constantin Film GmbH on 21 September 1964, and on 1 July 1965, Bertelsmann Publishing became the majority shareholder of Constantin. They attempted to increase output without increasing investment that resulted in the demise of many of the studio's popular film series, investment in sex films, and a stronger emphasis on releasing films from other nations rather than shooting their own. Bertelsmann sold its shares in 1969. The "old" Constantin Film GmbH was eventually declared bankrupt in October 1977.
