“"When Night Falls on the Reeperbahn" is a somewhat glossy production that bears some of the signs of its times, the sixties. This was when spy movies and spoofs were big sellers. It was when movies turned quirky or humorous with sixties humor. This appears in several sequences here. It comes in during a mud wrestling sequence in a club featuring female wrestlers, and it appears during several fights. It's sort of how the television Batman was done. Although for the most part the story is serious, it still maintains this underlying tone of being jocular.
        The story is narrated at times by a reporter, played by Erik Schumann. His narration and his role are cynical and humorous in that way. He moves in and out of the action. Hamburg has a new racket. Everyone involved is seemingly respectable, well-dressed and not impoverished. There is a group of young men, well-dressed who supply girls looking for sex and thrills and some money with LSD. They then cavort with the respectable but leering, lecherous and horny businessmen of Hamburg. Schumann is out to uncover this ring because one of the girls has had a bad trip and been killed in an auto accident. Schumann's helped out by Heinz Reincke, a minor pimp who likes to brawl. One of the gang members wants out because he's fallen in love with an innocent girl, and she's fodder for being given an LSD cocktail without her knowing it. The whole business turns murderous when one of the girls might talk.
        The movie is quite well done with nice camera work, good acting and color. It moves right along. It's not low budget. It exploits the LSD craze of the times, as this drug was introduced and became known at that time. Not at all a bad film for what it is.”
