Continuity mistake: In this scene we see John Wayne and others milking goats. The goats then get startled by a baby elephant and Wayne falls backwards on to the ground and you can see he takes the bowl with his right hand and the milk is thrown out of the bowl. In the next shot of him close up the bowl is on his head like a helmet when the bowl never even went on his head as he fell backwards. (01:09:20)
Factual error: The U.S. Paratrooper uses his "clicker", and the German answers with a "double" click-click - click-click. The Paratrooper stands up, and the German soldier shoots twice with his Mauser K98 without pulling back the bolt between shots, which is impossible.
Suggested correction: There could have been another German soldier present who fired as well.
Continuity mistake: The shadows in the scene with Lawrence sleeping on his camel are short because it's the middle of the day. In the next shot you see long shadows on the sand. When Ali wakes up Lawrence they are short again. (01:01:41)
Continuity mistake: Early in the courtroom scene there is a shot of Gregory Peck that is reversed. The part in his hair is not on the same side of his head that it is in the rest of the film.
Revealing mistake: The professor has a blowout, but all four tires on the car are fine. (02:04:30)
Factual error: Raymond is equipped with what is described as a high-power Soviet sniper rifle. However, the rifle he uses is actually a Japanese carbine.
Continuity mistake: In the scene where they ride to the top of a hill on horseback, you can see a white van and power lines in the distance.
Audio problem: When John Wayne has his back turned and tells the newspaper man "print that and he will kill you sure as hell", you can tell by the side of John Wayne's face that he isn't really saying anything.
Continuity mistake: Partway through the film, the car the principal characters are driving changes brand, between Peugeot and Mercedes.
Plot hole: When Annie Sullivan, as Helen Keller's teacher, gives Helen a doll that makes a sound, when they are alone in the small house, Helen upends the basket that holds all her dolls, but when the doll makes a sound, Helen grabs the doll and makes the sound the doll makes; but Helen is deaf, so how could she have learnt to imitate it?
Continuity mistake: The little motor boat that G. Peck uses appears to have lost its windshield from the time he is driving it to when it is tied up.
Continuity mistake: Approximately 46 minutes into the film, Robert Preston is testing a new bullwhip. The whip is in his left hand as he brings his arm back and cracks the whip. He brings the left arm back for a second crack, and the shot changes to a closer angle just as he brings the whip down, only now it is suddenly in his right hand and not the left. The editing, the sound effect, the arm swing all seem perfectly coordinated, except that the whip changed hands between camera set-ups.
Continuity mistake: Don Murray goes into the bathroom wearing a T-shirt under his shirt and tie (it clearly shows through the shirt). When he comes out he still has the shirt and tie on but the T-shirt has mysteriously disappeared.
Continuity mistake: Jane always pulls into her garage forward rear of car facing out. However, whenever Jane is seen pulling out of garage front of car is facing out.
