Continuity mistake: In the middle of the film just after the Japanese start attacking Pearl Harbor, Cuba Gooding Jr sees the captain injured. If you watch closely, the captain is pointing at Cuba but doesn't touch his arm, yet in some shots you can see that his hand is touching his arm. (01:30:05)
Continuity mistake: In the scene where Danny, Rafe and Jimmy Doolittle are on the deck of the Hornet talking about "returning" the friendship medals before the attack on Tokyo, you can see what appears to be a radar dish covered with a grey tarpaulin. The scene cuts back to Doolittle, Danny and Rafe talking some more, and then back to a wide shot of Doolittle walking away. The mysterious tarped object is completely gone now.
Continuity mistake: When Rafe and Evelyn go to the Queen Mary ship and they are rising on the platform, and kissing, one sweeping camera shot shows the handle of the elevator controls going straight up. This would mean that they had stopped, yet they are still moving up. A couple of seconds later, a close up of the handle shows that it is now in the position to move the elevator up.
Continuity mistake: When we see the Navy Department's "vacant sea map", there is a guy holding a cane and explaining what it means. He walks around the globe in the middle of the room holding onto the side of the globe with his left hand, but in the following shot his left hand is on the cane. (01:05:05)
Continuity mistake: In the scene where Rafe is burning his love letters on the beach after learning Evelyn is pregnant with Danny's child, when Danny and Rafe are talking there is a modern "dune fence" meant to keep people from walking on sensitive dune plants clearly visible in the background.
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. (00:55:10)
Continuity mistake: When Evelyn says goodbye to Rafe before the last raid, the angle in which Rafe is holding his head head changes between back and forth twice between clips.
Continuity mistake: When Rafe is taking Evelyn to the boat in the beginning of the movie to sit on the lighted platform, they clearly pass the same platform about 2 or 3 times before they get onto it.
Continuity mistake: On the island with Pearl Harbor when the girl and Ralf is sitting in the old car on the beach you can see the camera wagon in the bumper on the car.
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.
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)
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).
