Q: Tour de Force for William Holden . This is movie is an excellent WWII prisoner of war film. I was enamored immediately and for the entire length of this film. William Holden is perfect as an American POW caught in the middle between a mission dreamed up by his British companions and desire to sit the war out. Director David Lean is the master.
A:
POS
