Revealing mistake: In the scene where the medic gets shot, watch the shot where Upham brings the bags up to the injured medic. The next shot there is some fog which then reveals the injured medic. In this shot, watch carefully as the cast rips away the medic's shirt. If you look near the neck, you can see the fake stomach vest he is wearing for a split second - when the actor realizes he ripped too far up, he quickly covers it back up.
Continuity mistake: When they go to find Private Ryan there are eight of them, when they go to a French town and a solider picks up the little girl and he gets killed there are seven, right? Wrong. A few scenes later, the camera shows all eight of them marching on to the next town, only in a far away camera shot so it's hard to see.
Factual error: In the Ryan farmhouse scene, the camera pans across the room. You see a telephone hanging on the wall. That type of phone did not appear until at least the 1950s.
Continuity mistake: When Miller is collecting Upham from the group of translators and map readers, Upham is so confused and clumsy that he knocks everything off the table onto the floor (e.g. typewriter and helmets). Told by Miller to leave everything except his helmet, Upham picks up a German one by mistake. When sent back to the table to get his own, everything has miraculously jumped off the floor back onto the table.
Continuity mistake: In the scene in the Pentagon between several officers and General Marshall, when the camera pans over Marshall's left shoulder towards the officers, you can see that the colonel, who was missing his left arm in earlier scenes, has it again; it's missing again in the next shot. It may be just that his sleeve's rolled down in the middle shot, but that's still an error.
Revealing mistake: Just before the two American soldiers slap their grease coated "sticky bombs" on the passing German Tiger tank, you can clearly see two identically shaped grease stains on the first two wheels. Presumably nobody remembered to wipe off the wheels of the tank after a rehearsal or previous take of the scene.
Factual error: The Tiger tanks portrayed in the movie are actually Soviet T-34s. You could tell by looking at their wheels. Real Tigers had interleaved wheels. These Tigers had the T-34 suspension. Obviously, Tigers were so rare that another tank had to be substituted. But an excellent job was done to make the T-34s look like Tigers.
Revealing mistake: In the scene where the American soldiers are in the village listening to the French music on the record player, take a look at the stone pillars at either side of the doorway. The bullet patterns are all the same on each stone block. No doubt the same mould was used.
Revealing mistake: In the opening sequence Cpt Miller is wading through the sea with another man. You can see an odd looking square-shaped object clearly through his wet uniform. It may come as no surprise that a second later he is shot dead centre of the pocket. The object was obviously a charge.
Continuity mistake: After the taking of the beaches, and Miller returns for revised orders, the fleet in the background appears/disappears.
Continuity mistake: When Jackson has been given the dog tags to search through he looks for a place to sit. In this scene you see a black box with two yellow boxes at either side in the background. In the next scene the yellow box on the left has magically jumped up onto the black box in order for Jackson to kick it off and sit on it.
Revealing mistake: In the last battle in the village, a 20mm cannon killed the occupants on the tank. The camera zooms in to show the cannon ejecting spent shell casings, but if you slow it down you see that it is ejecting unfired rounds, or possibly spent blank rounds.
Factual error: In the end scene, after the final battle, Reiben is seen calling for a medic to assist Miller. When he gets up to go and find a medic, he picks up his BAR by the barrel. Having just fought in a fairly long action with a high rate of fire, his BAR barrel would be far too hot to touch, let alone pick the rifle up by. It would take 15 or 20 mins for it to cool down enough to handle. He should have picked it up by the foregrip (The wooden bit under the barrel).
Continuity mistake: At the start of the film in the telegraph scene, a Captain goes into the Colonel's office to tell him about the Ryan brothers. He is holding a folder which he puts on the Colonel's desk, but we don't see him pick it back up in all the following shots, yet it suddenly appears back in his hands.
Continuity mistake: In the Belltower in Ramelle where Jackson and Parker are shooting away, there is one scene where you see Parker running out of .30 caliber ammunition. One second the MG uses a belt with ammunition, in the close up, you see the more modern disintegrating link.
Continuity mistake: At the end when Tom Hanks has just died, there is a distant shot of Ryan standing there in disbelief. By Tom Hanks left leg is a helmet, upside down. The next shot is from above and the helmet has flipped over.
Continuity mistake: In the scene where Mellish is in the fight to the death with the German. Mellish pulls out his bayonet with an underhand grip. In the next shot he has it with an overhand grip.
Continuity mistake: In the scene where the American soldiers are about to ambush the Tiger tank, look at the empty belt on the right side of CPL Henderson's machine gun. Its length changes from shot to shot before he opens fire.
Revealing mistake: In the scene where the American goes to sit down and hits a block of wood that hits a wall the wall falls down and there are German soldiers. In the next shot they are screaming, notice the man standing in front of the table the camera makes a close of his face he is the one without a helmet. In the next shot all of them get shot right? Well look closely at that man in front of the table he gets shot and goes to sit down on the table and misses the table. He quickly sits back on the table. Look closely and you'll see it.
Revealing mistake: In the closing battle of the film we see one of the American soldiers with an ammunition belt around his neck. The striker marks on the primers indicate that the belt is made up of fired (ie. useless) cases which have had bullets put back into them so they look normal.
