Factual error: In the scene where Admiral Kimmel is inspecting the crew of the battleship an aide comes up with a message to send some ships to the Atlantic. Admiral Kimmel starts complaining about the orders. No Admiral would ever do this especially in front of enlisted men. In fact he was placed in charge of the Pacific fleet when his predecessor complained about moving the fleet from San Diego to Pearl Harbor.
Factual error: For some reason, Danny believes Rafe's story that he's been officially assigned to an RAF Eagle Squadron for "combat training." While almost 7,000 Americans did volunteer to fly for England before Pearl Harbor, these were either as civilians or Americans who joined the Royal Canadian Air Force. It was against the law for any citizen to fight for a belligerent power while America was neutral, so Rafe's superiors couldn't have ordered him to fight for Britain, and Danny would have known that.
Continuity mistake: In the scene where Rafe is fighting for Britain his plane gets hit. As it goes down into the water, it is day. Later when they show him swimming out of the plane and to the surface, it is night. (00:41:30 - 01:10:10)
Visible crew/equipment: When Dorie Miller is in the hall of the ship, he is holding a tea or coffee set, on the left side of the screen you can see the hands of the camera focus puller and the wireless focus controller for a brief moment.
Factual error: In the scene where the nurses walk among the flag-draped coffins after the attack, the nurses are in stylish civilian outfits. Those nurses are all Naval personnel, and once war was declared they were ordered to be in uniform at all times, except when in the privacy of their quarters.
Continuity mistake: When Rafe and Evelyn go to the Queen Mary ship and they are rising on the platform, and kissing, one camera shot shows them rising and when they stop the camera does a close up and you can see they are still at the red painted water line indicator. The next shot shows them above it again.
Factual error: The nurses are wearing far too much make up when on duty: bright red lipstick, eyeliner, mascara and blusher expertly applied. Military medical nurses are allowed subtle skin tone make up and surgical nurses none at all. It's always been that way, right back to the 1890s when the British Army first hired nurses.
Factual error: Towards the end of the Special Edition DVD there are shots of various ships being blown up. One of these ships is a 1960's British Leander Class frigate being used as a missile target. It's painted a very light grey and has cross markings all along the ship's side.
Factual error: The P-40s depicted in the movie were later models that were not around during Pearl Harbor. The ones used in filming were probably either P-40Ks, P-40Ms, or P-40Ns instead of the historically correct P-40Bs or P-40Cs that were around at the time of the attack. This is noticeable because the planes in the movie have three guns mounted on each wing while a correct P-40 would have two mounted on each wing and two on the engine cowling.
Factual error: When they show the whole fleet sailing, there is clearly a nuclear submarine out front. It is easily distinguished by its teardrop shaped hull.
Continuity mistake: The hangar used in the "Mitchell" Field scene is the same one used later in the film as Clark Field, with the world "Mitchell" removed, leaving only the word "Field."
Factual error: In the beginning of the film, there are scenes at "Mitchell Field" on Long Island, New York. The actual spelling is "Mitchel Field." (00:04:50)
Factual error: When Eveleyn and Rafe are going to the Queen Mary, you can see to the left the modern buildings for the actual New York. (00:24:25)
Factual error: When the MPs drive on to the golf course to alert the commander of the attack, the Jeep they're driving is a Korean War era M-38. (01:24:00)
Factual error: In the control tower scene after the stunt flying, look closely in the background and you will see the shapes of E-2 Hawkeyes. The E-2 wasn't in service until the early 60's.
