Continuity mistake: In the very beginning of the movie a Japanese prisoner train is being filmed from the roof view with a Japanese soldier at a machine gun with a tripod riding on the roof. The Japanese soldier has his legs resting up on a wooden pallet type platform. When the train car approaches a few seconds later toward British soldiers a working on the train track the Japanese soldier's legs are now on the train car roof and no wooden pallet structure is visible.
