Continuity mistake: The commandos are in the river, at night and they are setting the charges on the bridge, the variety show is going on at the same time. Between the British soldiers heads and the roof of the auditorium, the Japanese soldiers are standing in bright sunlight.
Continuity mistake: When the commandos start placing the demolition charges, the roll of wire is a very bright white, but next morning the wire is black.
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.

Suggested correction: There actually two Japanese guards on the train, one near the front of the flat car containing the POWs near the locomotive and one at the rear of the car. That's why they look different.
