The film producer Wolf C. HARTWIG was the godfather of West German adventure films in the 1960s with his RAPID film. The protagonist of a new series was to be introduced with the German actor Thomas ALDER (1932-1968) as private detective Rolf Torring. However, the film, shot in Thailand, was not successful enough at the box office (at least 1,088,000 admissions in CONSTANTIN's distribution) for a sequel.
The plot is not particularly original, but offers exciting entertainment for fans of German adventure flicks. The internationally successful actors Peter CARSTEN and Horst FRANK also appear in other roles. Serge NUBRET (1938-2011) from France is there as a muscle man. And what's also interesting is that the Thai actress Chitra RATANA essentially completed a very early jungle test in a scene with 1000 spiders.
