Prolific producer & writer Harry Alan Towers concocted the story for this lightly entertaining, eminently forgettable action-thriller set in South Africa. Lex Barker ("The Torture Chamber of Dr. Sadism") stars as "Steve Martin" (!), an American private eye hired by copper mine owner Wexler (Walter Rilla, "The Scarlet Pimpernel") to find out who murdered his valet, and why. It turns out that the crime has a connection to the men in a key photograph left by the victims' body.
The main novelty here is the Cape Town setting. It's very attractively photographed by Nicolas Roeg, and the scenery is often breathtaking. The story is enjoyable enough, but nothing special. It doesn't help that the ending is kind of clumsy, as the antagonist basically reveals themselves in a rather abrupt manner.
Still, the second unit work is first-rate. Those scenes of driving by the sea are excellent, and the film actually stops cold for about three or four minutes for a major underwater sequence that, much like the scenes on land, is very well photographed. The jazzy score by Johnny Douglas is jaunty and fun to listen to.
The cast is enjoyable to watch. Barker is a charismatic hero who of course always has time for the ladies. But then, so does jovial police inspector Lean (Ronald Fraser, "Fathom"). Fraser and French babe Veronique Vendell ("Barbarella") are most amusing, with the latter playing Wexlers' hot-to-trot stepdaughter who practically throws herself at Steve. Danish beauty Ann Smyrner ("Reptilicus") is appealing as Wexlers' secretary. Dietmar Schonherr (who also acted for director Robert Lynn in "Mozambique") and Gert van den Bergh ("The Naked Prey") also co-star.
All in all, this is the kind of non-challenging, easygoing, amiable entertainment that you throw on if you just want to relax for an hour and a half.
Six out of 10.
