The South African landscapes are by far the most interesting feature of "The Rutanga Tapes", also known as "Killer Instinct." The story of a chemical weapons plant hidden in the African jungle, posing as a fertilizer factory, is both murky and confusing. Not until three quarters of the movie has run do things somewhat crystalize after David Dukes carefully explains to Susan Anspach what is going on. Acting by anyone not named Dukes is simply awful. In fact the Bushman, who speaks in his own language shows better acting skills than everyone else. Arnold Vosloo is about as believable as an Arab as he would be as Santa Claus. Susan Anspach gives a performance that screams she would rather be anywhere else than in the oppressive African desert. Unless you are completely enamored with one of the actors, this is one to skip.
