Other mistake: In the earlier part of the movie (at Corregidor Philippines) where Japanese warplanes are bombing the field camp, it can be seen that a warplane approaching its target can be seen with no bomb attached underneath, and yet an explosion takes place on a targeted machine gun position. The action scene is repeated minutes later, this time hitting the escaping and running soldiers.
Other mistake: After Jesus is taken down from the cross, he blinks for a moment.
