Continuity mistake: When the B-26 bombers from Midway attack (aside from being to many as mentioned in another posted mistake) the overhead view of the formation shows the B-26 in the back, middle of the formation hit. Both engines erupt in flames and the bomber starts to drop from the formation. The scene then cuts to the Japanese gunners' perspective, showing the B-26 formation from below. The bomber in the back, middle of the formation is no longer on fire and moments later the B-26 just forward and to the left is hit and the engines start to burn. If this was intended to show an overlap in time of the same scene, as simultaneously viewed from two different perspectives, then the visual effects of the flames, from the Japanese perspective, was applied to the wrong bomber in the formation.
Continuity mistake: The injury Schofield suffers to his neck is healed by the time that he gets to the front line.
Continuity mistake: During their first night at the camp, Jojo and his friend are talking while they play with their knives. During the scene the knives change position between cuts (blatant especially when they mention the brussels sprouts or when he rolls to the other side to sleep). (00:08:40)
