This German-Italian co-production, a low budget spy thriller, was shot in South Africa by the director team Wolfgang Schleif (German version) and Alfredo Medori (Italian version). "In the Nest of the Yellow Viper" tells the story of two agents (Hellmut Lange and Peer Schmidt) fighting a murderous bunch of rogues known as the "Yellow Viper". The agents are determined to uncover the Viper's leader, but he communicates with the gang members only via radio, so nobody knows who he is.
Well cast in other roles with Moira Orfei, Massimo Serato and Gérard Landry, the film is passable, but modest entertainment. I liked some ideas of the script, for example one killer who discovers his conscience and changes sides, or the clever disguise of Peer Schmidt who poses as a hopeless alcoholic so nobody will take him seriously as an agent.
