Plot hole: Near the end of the Tokyo raid, Col. Doolittle orders his radio operator to "break radio silence" so he can address the rest of the planes. For the duration of the raid, though, intelligence officers had been listening to radio transmissions back at Pearl (other users have already commented that this in itself is a historical error). If these transmissions were being heard at Pearl, there was obviously no radio silence to begin with.
Continuity mistake: When one of the Men are speaking to the President about the boys having to take the airplanes off the carrier too soon, you can see there's a ring on his left pinky finger, but no wedding ring.
Factual error: As the RAF aircrew are running for their aircraft during the scramble sequence, one of the Spitfires can be seen showing a serial of 'AR4474' briefly. This is incorrect not only for a wartime Spitfire, but is completely out of sequence for any UK military aircraft. All four flying Spitfires used during filming had similar inaccurate serials. (00:38:20)
Factual error: During the attack on Pearl Harbor Danny and Rafe take off from an airfield and then fly to defend battleship row. As they fly over the harbor there are several Newport Class LSTs shown at anchor. This type of ship did not exist until 1966.
Factual error: When Ben Affleck is about to ditch his B-25 in China, and yells that the #1 engine is out, the port engine is shown spinning to a stop, with the propeller already feathered. A perfectly functioning engine would not have its propeller feathered; the pilot would feather it only after the engine stopped, to reduce drag.
Other mistake: In the scene where Danny and Evelyn are flying in a plane to watch the sunset their hairs don't move an inch and stay brushed and perfect all the time, even after the plane makes a 360ยบ turn.
Factual error: In the RAF squadron scene, the lined up Spitfires are the wrong mark for the period. For early 1941, the correct mark would have been a mark V. The Spitfires are later, as they have six exhaust outlets per side, and several have four-bladed propellers, neither feature being present on mark V Spitfires.
Continuity mistake: At the start of the attack, the Japanese fly past a baseball court with some kids playing baseball. In one shot we see perhaps two or three kids in the batting cage. If you look to the far left you can see a woman. In the following shot she is now suddenly where the batter was. (01:23:10)
Continuity mistake: When Rafe and Evelyn go to the Queen Mary and are rising on the boat is one sweeping camera shot. Look to the right as their boat goes up and you can see the film crew going up on a platform. Note that the next shot of them on the boat is filmed from that platform.
Continuity mistake: When the cook uses the mounted gun it has two ammo cases and then during the scene it changes between one and two cases and the right hand one is even open at one stage. (01:36:40 - 01:37:15)
Continuity mistake: When Rafe comes back for the first time after supposedly being dead and you see his reflection in the glass before meeting his lover, as the camera pans across the room you can see a green light moving on the wall as the camera moves. I'm not sure what it is but it could be the light to indicate the camera is on.
Continuity mistake: When Danny & Rafe take off from the sattellite airfield their landing gear is (obviously) down. You see a shot of them from behind like this. Two seconds later they just clear a building, in the heat of a combat takeoff,and both sets of landing gear are fully retracted.
Continuity mistake: When Rafe returns and is having a drink with his friends in the beach club, if you watch Rafe's fingers on the glass of whiskey, they change from being held over the top of the glass to being held at the side of the glass between shots. (01:13:55)
Continuity mistake: When Rafe's Spitfire crashes into the water, the preceding shot shows it to be diving nose first, In the next shot however, it lands virtually flat.
Continuity mistake: After Rafe hits himself with the cork, Evelyn puts snow on it. She then is seen removing it, but when the camera angle changes, the snow is back on his nose.
Continuity mistake: As the bombs land and chaos ensues in Pearl Harbor, in a scene where some classic cars are parked on the beach, you can clearly see the card-board squares that the cars' wheels are parked on (presumably to keep them from digging in to the sand.)
Continuity mistake: When Evelyn and Danny are having a drink in a cafe going over the good times with Rafe, we see the camera pan down from a height, in this shot we see Danny holding onto a cup in his right hand which is sitting on a saucer on the table, but in the following shot he is just putting it down on the table. (00:52:45)
Other mistake: During take off from the carrier, 600 miles at sea, trees and a shoreline are in the distance.
Continuity mistake: When Rafe's girlfriend is looking for him at the train station there's a train behind her that says "Silver Horizon." But when the camera shows Rafe looking at his girlfriend the words on the train are gone.
Character mistake: When threatening Evelyn with jail, the Army Signals officer says "Brig" which would be a Navy jail. In the Army the appropriate threat of incarceration would be the stockade.
Answer: He is in the scene where the smaller air-base is being attacked by the Japanese. You have to look really closely but he is the driver of one of the jeeps right before the Japanese bomb drops (the one that seems to be a dud and then explodes). Also, Matt seems to be one of the gunners on one of the first ships at Pearl Harbor to return fire (this is not verified but in slo-mo, one of the gunners seems to be him).
