Continuity mistake: When the Japanese ship is about to be torpedoed, there are no numbers or letters on its side. In the next shot, when the ship explodes, a large white "265" is visible on the port side of the ship.
Continuity mistake: When Charlie Allnut grabs a bottle of gin from the box, all the bottles in it are wrapped with paper for transport. But when Rose Sayer takes the bottles out of the box to empty them into the river, the paper is gone (from the movements of her hand/wrist, you can tell that she doesn't unwrap the paper from the bottles).
Continuity mistake: During combat a pilot is shown to be wounded in his right leg. As he is coming in to land, two further shots of him in the cockpit now show him to be wounded in his left leg. Some blood stain patterns on his gear, also the position of his helmet chin strap, also change position from left to right.
Continuity mistake: When the Sutherland engages the four French ships, her masts are shot to doll rags, with the upper masts and fighting tops plunging to the deck. However, the lower shrouds and ratlines, which are attached to the tops, remain intact.
Continuity mistake: Henry has his paisley bandana on his head when charging but loses it along the charge, but it reappears on his head during the conclusion of the battle charge. (01:08:55)
