This is one of those movies that made the German cinema of the 1960ies and early 1970ies infamous. Knowing the person of writer/director Rolf Olsen, he was a master in his class giving the audience exactly the movies the wanted or - in this case - deserved. It is a pity you don't see Olsen as an actor here, because his intended overacting gives most of his movies a touch of an vaudeville act. Nevertheless most of this movie is not worth to mention, but compared to today's teenager-aimed uhm... comedies this one stands at least for some laughs, thanks to the performances of Gunther Philipp, Ruth Stephan and (Dr.) Kurt Nachmann. Besides that, Hansi Kraus is once again Hansi Kraus, and the rest is not worth mentioning.
The story itself is a weird mish-mash and has neither point nor punchline, but obviously the movie did its job in its days.
Besides all that it's an interesting fact that the movie - although set in Upper Bavaria - was shot entirely in Carinthia/Austria.
