Its a 1960 British movie based on a play by the same name.
ok, one more:
Seven men who are thrown into the centre of a war filled Malaysian jungle find refuge in a hut. Two are war hardened veterans while the others are inexperienced to the cruel reality of war. Their only contact with the outside world is a fading radio transmitter. The realness of their situation doesn’t first sink in and they banter along contentedly. But when they capture one of the enemies, tempers are flared, relationships are built and crumble, authority is questioned and accusations fly to form a disturbing climax.
