In real life, Lee Marvin is a Marine that received a purple heart after being shot in the buttox during the battle for Saipan. Now here he is afterwards making movies where he is confronting his adversary and being the representative for the American side of the WWII GI psyche. His opposite is a Japanese soldier who equally does a splendid job to bring one up to speed with his culture. Both different and somehow the same. United together by a common goal of survival, yet on a hair trigger to let their warrior spirit flare. Interesting concept for a movie. Well done, appropriately cast.
