King Rat (1965) Part 1 of 3

When Singapore surrendered to the Japanese in 1942, the Allied P.O.W.s, mostly British, but including a few Americans, were incarcerated in Changi prison. This was a P.O.W. camp like no other. There were no walls or barbed-wire fences, for the simple reason that there was no place for the prisoners to which to escape. Included among the prisoners is the American Corporal King (George Segal), a wheeler-dealer who has managed to established a pretty good life for himself in the camp. While most of the prisoners are near starvation and have uniforms that are in tatters, King eats well and and has crisp clean clothes to wear every day. His nemesis is Lieutenant Robin Grey (Sir Tom Courtenay), the camp Provost who attempts to keep good order and discipline. He knows that King is breaking camp rules by bartering with the Japanese, but can't quite get the evidence he needs to stop him. King soon forms a friendship with Lieutenant Peter Marlowe (James Fox), an upper class British officer who is fascinated with King's style and no-rules approach to life. As the story develops, it reveals the hypocrisy of the British class system and for King, the fact that his position in Changi's "society" is tenuous as best.

From IMDB:

Great POW Movie
I had never heard of this movie. It came on late one night on cable and I watched it. I was very impressed. The performances in the movie are Oscar caliber. George Segal gave probably the best performance of his career. He plays an American stuck in a Japanese POW camp who manages to always make some dough on the side. He is manipulative and arrogant but his performance is credible and appealing. Also, the way the camp itself is projected as a miserable, fly-infested, hot and godawful hellhole is hard to forget.

James Fox also gives an outstanding performance as Segal's British counterpart who come under Segal's spell and begins to do alot of his dirty work for him. This is a movie you will not soon forget. Now, keep in mind that since this movie was made in 1965, it is tame in terms of its depiction of violence but that does not take away from its overall message. Great movie!
