Continuity mistake: As the Doolittle Raiders are taking off from the aircraft carrier there are several sweeping views of the carrier task force as the planes fly off. The decks of the carriers are obviously modern US carriers with the landing portion of the flight deck angled out about 10° from the catapult direction of the flight deck.
Continuity mistake: In the scene when Danny and Evelyn are at the restaurant after they hear the news about Rafe's death, as the camera comes in on them from outside her milkshake is full to the point of overflowing but when they switch angles to show them from the inside the milkshake is half gone.
Continuity mistake: When one of the pilots of the "pride of the pacific" crew is painting a woman on the side of his airplane, he is brushing it on with his right hand, but in the following closeup, he is now brushing it on with his left, then back to his right in the wider shot.
Continuity mistake: In another scene when Danny and Evelyn are at the Black Cat diner after leaving the cinema she gets up to leave first, but when she gets up there is no hankie on the table. After the camera shows her walking out the door, it cuts back to Danny who picks up the hankie, which was not there a second ago.
