They had the makings of a good movie here. A group of soldiers are taken out to a jungle camp for a rigorous P.O.W. survival course, but instead of a "controlled" experiment, they begin to suspect that the camp's commander has gone "over the edge" and is turning the experiment into a deadly reality. However, the premise is muddled by adding a female soldier to the mix, a choice which seems gimmicky and which throws off-balance the rest of the plot. (Ironically, the female angle is probably what "sold" the idea to the studio.) Some viewers may enjoy the male-bondage scenes but it's sad to read that the actor who plays Ripkin and is memorably shown tied bare-chested to a X-shaped cross committed suicide in 2001. Anthony Zerbe, America's answer to Frank Thring, is unimaginatively cast as the villain. And yes, the movie seriously weakens in the last 10 minutes.
