Crittendon's Commandos - S5-E25
Character mistake: To have an excuse not to start up the truck motor, Schultz claims his driver's license has expired. German driver's licenses don't expire.
Continuity mistake: As in S5: Ep1 "Hogan Goes Hollywood", the bridge Hogan looks at through binoculars is vastly different than the one wired with explosives. When the bridge blows up, it is a re-use of the footage from earlier episodes.
Continuity mistake: Even though Carter pops his head out of the hatch to talk to Hogan, it isn't Carter that's seen in the window as the tank approaches Hogan's position.
Visible crew/equipment: As Klink and Schultz approach the barracks where Le Beau is "weightlifting", there is a cord or cable along the ground that would be for studio equipment.
Continuity mistake: As Schultz takes the balloons away from Hogan, Newkirk is nowhere to be seen. A second later, he witnesses the entire scene.
Continuity mistake: As Klink asks about the forecast, his hand is around the microphone end of the receiver, then a moment later it's around the handle.
Continuity mistake: As the men are lined up, Klink starts to grill Hogan. Klink has his pistol aimed directly at Hogan, then it's at a 35 degree angle toward and close to Hogan's face. A moment later it's about two feet away from his face.
Continuity mistake: In Room 210, Newkirk's sleeves are down to his wrists, but in the close up of his hands, the sleeves are totally missing.
Other mistake: As Schultz goes to stick a pin in the map, he supposedly hits his finger. But if you look closely, he actually stuck it in the map at the very tip of his finger. This is clear because he didn't move the pin at all.
Continuity mistake: In this episode, the Notausgang (Emergency Exit) sign is over the door. In other episodes, it is on the door.
Continuity mistake: The bridge Buckles and the boys put TNT on is significantly different than the one blown up. Also, the one destroyed is a re-used shot of a bridge being blown up.
Other mistake: As Buckles holds up the scale model of the Bismarck, the diagonal cut where it's supposed to "break" is visible.
Six Lessons from Madame LaGrange - S5-E22
Character mistake: The SS guard salutes Major Hochstetter with his palm out, in the British fashion. Firstly, German soldiers salute palm-down, secondly, by the Wehrmacht (and SS) military protocol, he should just click his heels and not salute at all when receiving an order.
Factual error: About 10 minutes into the show, Newkirk is using binoculars to watch Klink put the combination into his safe. He goes one direction for the first number, the opposite direction for the second number, then goes in the same direction for third number. Opposite for the fourth number. For the radial tumblers to set, it has to be alternating directions.
Continuity mistake: Col. Klink is eating lunch. The meat on his plate moves from the left side to the right. (00:16:00 - 00:17:00)
The Kommandant Dies at Dawn - S5-E6
Continuity mistake: As Schultz is eating from the tray he predominantly uses his left hand in each change of shot. When he takes the last piece, he has the toothpick in his left hand, when the shot changes he now has it in his right hand. (00:09:50)
Revealing mistake: The first shot of the train the view is normal. Then after Lebeau starts in reverse you can see the smoke trail going in the wrong direction. The final shot shows the train moving in reverse, but notice the smoke trail is going to the rear of the train instead of the front as it should be, since it's moving in reverse. (00:15:05 - 00:22:25)
Other mistake: As Schultz tries to find Flensheim on the wall map, what he's checking isn't a road map, but a city plan with a harbor on it.
Six Lessons from Madame LaGrange - S5-E22
Factual error: Hilda is writing with her left hand. At the time of the Third Reich, it was still the practice in Germany to force left-handed children to learn to write with their right hand.
The Sergeant's Analyst - S5-E23
Factual error: In this episode, the running gag is that Schultz keeps flattening Col. Hogan's pumpernickel loaves. In reality, pumpernickel is a very compact bread that contains virtually no air at all and is impossible to flatten in this way. The shape is also wrong: pumpernickel is almost always baked in rectangular baking pans. To avoid confusion: the original, German pumpernickel is quite different from what's sometimes referred to as pumpernickel in England and America.
