This movie may have come out sometime around 10-20 years ago, but I’m not certain. I only saw the beginning.
It was a POW camp with US (or probably some WW2 allied nations) prisoners. There was a US soldier who was being crucified, or at least tied up on a post as punishment. I think it was a Japanese POW camp.
An imprisoned soldier goes over and frees the guy tied up. I don’t know if the war ended, or what exactly.
Thats all I remember.
