This WWII prison camp drama set in the steaming Burmese jungle is a metaphor for the horrors of World War II and features what is easily George Segal's best dramatic performance, an even better one by James Fox, and lean, taut direction from Bryan Forbes. It also offers many insights on the British class system and takes a very grimly pessimistic view of the human condition. There is some humor but it is darkly sardonic and somewhat sadistic in nature. Segal's con artist extrodinaire Sergeant King is the dark side of Segeant Bilko and he employs bitter cynicism as opposed to the wisecracking humor of Phil Silvers. It is based on a novel by James Clavell, and is a better film, if not more entertaining, than the author's "The Great Escape," which was released a couple of years prior to "Rat." With the exception of Segal, the British cast members greatly outshine their American counterparts. Tom Courtenay, the always wonderful Denholm Elliott, John Mills, Gerald Sim, Leonard Rossiter, and Alan Webb all contribute memorable characterizations, but by far the best is James Donald as the compassionate, humane camp doctor, practically reprising his role of eight years earlier in "Bridge on the Rver Kwai' also set in a Burmese prison camp.
