Continuity mistake: In the preparation for the big battle in the village, the Americans count up on equipment left useable for the impending fight. A soldier lists what's left including two .30 caliber machine guns. In the preparation for the ambush of the Germans you see two .30 calibers being prepped for action by the American officers up the church tower and in the rubble, and then a third is carried past by an extra.
Continuity mistake: When discovering that 3 of the 4 brothers were killed, it's stated that they were all in the same company until they were split after the Juneau was sunk. We also see a few shots later when the Army car is pulling up to the mother's house that there is a picture of all 4 of them together in uniform. When Miller and Ryan are talking about Ryan's memory of his brother towards the end of the movie, he states that the last time the 4 of them were together was the night of the barn accident before Dan went to basic. (00:29:30)
Continuity mistake: When Miller's men and the other captain's men find the French family hiding in a partly destroyed house, Caparzo goes up to get the kid and gives her his necklace, but in the following shot he's giving it to her again. In the shot after it's gone from the kids hand, then reappears again when he is walking towards Miller. (00:50:00)
Continuity mistake: When the two infantries are waiting for the enemy, Upham, Reiben and Horvath are sitting on some steps outside a building listening to music. In the wide shot Reiben is looking at his fingers but in the following shot his hands are crossed and is holding his arms. (01:56:25)
Continuity mistake: When Miller's men reach the town where the first Ryan is (the wrong one), Miller tells Ryan the bad news about his brothers. When Ryan starts to cry and leans over to his captain the captain's hand is on Ryan's head, but in the following shot it is on the top of his back. (00:59:25)
Continuity mistake: When Mellish is in the house with the other soldier, and the other soldier shoots at the wall, just after this shot, the camera pans back to the two soldiers, if you look at the fireplace and chair, it looks like they are covered with dust and dirt, but in the overhead shot of the two soldiers, the fireplace and chair look brand new. (02:16:50)
Continuity mistake: In the beach scene, a GI takes a shot in the helmet, removes his helmet while he collects his sense, and is promptly shot in the head. As he falls back, his head lolls back, yet when the camera angle changes, his chin is tucked down in his chest. (00:17:40)
Continuity mistake: In the scene where the two infantries are waiting by the bridge for the enemy, when Reiben, Upham and Horvath are on some steps, Fish walks up and sits down in front of Reiben. Fish is taking a puff of his cigarette holding it in his right hand, but in the following shot the cigarette is now in his left hand. (01:57:05)
Continuity mistake: In the final battle in the French Village, the Americans are attacked by two Tiger tanks, two Panzer tanks, etc. The Americans use a sticky bomb to turn the first Tiger into a roadblock. If you look at the roadwheels of the tank when the troops are attaching the sticky bombs, you can see that one of them has a large chunk of rubber missing. Later on, when Capt. Miller is staring down the second Tiger as it crosses the bridge, you can see that it too has a large chunk of rubber missing from the same roadwheel - same tank.
Continuity mistake: During the beach scene, Miller is kneeling at the rear of a Belgian fence talking about the beach being pre-sighted. There is a soldier in front of the fence who gets shot three or four times. If you look the first scene, he gets shot in the upper leg area, then when Miller moves out from behind the obstacle, the bullet wound has magically disappeared. (00:11:15)
Continuity mistake: Just before the church steeple gets blown up at the end, we see through the window looking down, and the front of the tank starts to turn. The sniper fires some shots and the tank starts to make the same turn again, but we can see more of it this time.
Continuity mistake: In the first town the group comes to (the one where Caparzo is killed) they meet up with the Airborne troops and the Airborne Sergeant. They then move through the town to find the Airborne Captain. Right after they start this move the Airborne Sgt. stops and drops to a knee before moving on. When he gets up and moves, the coiled up rope (that all the Airborne carry) falls out of the left side of his back-pack. No-one notices it and they all keep moving. A couple of seconds later they show him with Miller, and the rope is back in his back-pack like it magically reappeared.
Continuity mistake: During the Omaha Beach scene where Captain Miller is at the front of the concrete bunker and calls upon Jackson to get into one of the impact craters, Miller moves behind Jackson. When Miller makes the move for the diversion he puts his hand on Jackson's right shoulder but in the following shot Miller is at least 2 to 3 feet away from Jackson. (00:20:20)
Continuity mistake: When Miller's men are about to take the bunker under the radar tower, they are kneeling on the ground behind some bushes discussing their flanking moves and Jackson is about two feet away from Reiben to his left, but when it cuts Jackson is now behind Reiben. (01:22:35)
Continuity mistake: In the scene near the end, when two soldiers are in a row boat packing a bag with explosives, in the overhead shot the guy at the back of the boat puts the oar into the water to his right, but in the following shot from behind the oar is on the other side of the boat. (01:51:40)
Continuity mistake: After Caparzo has died from the sniper bullet, when Miller's men are grouped around Caparzo's body, Horvath is holding his gun in his right hand pointing it to the ground with his left arm by his side, but in the following shot, when Miller walks up, he is holding his weapon at waist height. (00:54:25)
Continuity mistake: When Miller has just explained to Ryan that his comrades came to take him back, Miller talks to Horvath alone. While Horvath is talking over his shoulder, you clearly see him moving his hands in the next shot, from an angle just past Miller, his hands are held tight to his gun. (01:48:40)
