Continuity mistake: Just after Rafe pops himself in the nose with the champagne cork, there is a bit of blood running down his right cheek. It disappears when the camera cuts back to him.
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 25 degrees from the catapult direction of the flight deck.
Continuity mistake: On the morning after the love scene with Evelyn and Danny, they are talking and she puts her head on his right shoulder and starts crying. The camera pulls back and she is still crying on his shoulder - but this time on his left shoulder, not his right.
Visible crew/equipment: In the scene where the Japanese planes are taking off, there is a shot where, in the upper left hand corner, you can get a glimpse of the helicopter that the crew used to film aerial shots.
Continuity mistake: During the Battle of Britain sequence, in the scene where Rafe gets shot down he can't open his canopy to bail out so he shoots holes in it with his pistol. In the wide shots of the plane the canopy is whole.
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.
Revealing mistake: In the scene where Rafe returns from England, Evie is busy with something. Camera slowly zooms out from Evie and moves right to show Rafe's reflection on the window. Look carefully. You can clearly see the red light of the camera reflecting back, not from the window that reflects Rafe, but the mirror on Evelyn's right.
Continuity mistake: In the scene in front of the hotel on the night before Rafe ships out to England, Evelyn puts a scarf around his neck. There is a camera shot from his back: no scarf; then another one from his front, and he's wearing the scarf again.
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.
