Continuity mistake: After shooting the bridge with the tank, a cap at the end of the tank barrel is off.When carter says he is going to miss a captured film, the cap is on. In the next shot the cap is off again.
Suggested correction: There is no mistake. That was not the end of the gun barrel. Look closely.
Continuity mistake: As Major Tepple (Morrison) lays the deck of cards in Hogan's room on the table, the bottom card is not neatly in the deck. When the camera cuts to another angle, the deck is neatly stacked.
Visible crew/equipment: After Hogan goes down into the tunnel in Klink's quarters, the stove moves back in place. As it does, the wire on the floor pulling the stove back in place is visible.
Colonel Klink's Secret Weapon - S2-E28
Continuity mistake: When Franks turns in his report to be signed, Klink said "Kommandant's efficiency reports are six weeks behind." When he talks to Hogan later to get rid of Franks, he said the reports were six months behind.
A Klink, a Bomb and a Short Fuse - S2-E8
Visible crew/equipment: As Burkhalter and Klink walk toward the office, the shadows of the crew, camera and lighting appear on camera.
The Flame Grows Higher - S1-E31
Revealing mistake: As Hogan, Le Beau, and Newkirk help Schultz up the slope to the "forest fire", there is lumber stacked across a low spot in the top of the bank and covered with "snow" and grass. Probably meant as a path.
Continuity mistake: When Schultz comes out, he talks to the guard posted there. A moment later, the guard is gone.
Other mistake: The wooden steps in front of the office look to be one plank measuring 3" by 18", but in the collapse under Klink, they appear to be two pieces. Also, Le Beau sawed through the middle support, but neither Schultz or Klink step on it.
Revealing mistake: As Klink steps off the porch of his office, in the long shot you can tell it is his stunt double.
Continuity mistake: When Helga brings in Klink's dinner and sits it down, Klink takes off his monocle. In the close up, it's on and his hands are folded, then he points to a chess piece, contemplating a move. In the wide shot, he's holding his monocle, and puts it on.
Continuity mistake: The breast eagle on Schultz's uniform is sewn on backwards after the first season, and his belt buckle also changes from a Luftwaffe buckle to a different one.
Watch the Trains Go By - S4-E19
Continuity mistake: As Schultz is by the car, Hogan is behind the fire brigade equipment. When Klink calls Schultz, Hogan gets up from behind the equipment. A second later, in a closeup, he comes up from behind the equipment again.
Visible crew/equipment: Every time the boys use a flashlight to signal the planes, you can see the camera crew and equipment.
Factual error: While the show always made it winter time by having snow on everything (salt piles strewn about) and icicles on all the windows, this episode has an actual date of occurrence, June 6, 1944. They help to solve the snow on the set by taping the whole episode inside. However, the windows still all have the ice formations on them. It's late spring.
The Top Secret Top Coat - S2-E29
Factual error: In Klink's quarters, there's an (obviously fake) banana in the fruit bowl. Bananas were luxury items in Europe in the 1940s, and certainly so in war-torn Germany. The majority of Germans didn't have access to exotic fruit until the 1960s, and fake fruit of this type wasn't available then either.
German Bridge Is Falling Down - S1-E7
Character mistake: When counting the prisoners right at the beginning of the episode, Schultz counts to 15. However, including Hogan there are 19 men in formation.
German Bridge Is Falling Down - S1-E7
Continuity mistake: When we see the men lighting cigarettes, there are 25 people forming the arrow. When we are treated to an aerial view of it, there are 37 dots of light visible.
German Bridge Is Falling Down - S1-E7
Plot hole: We see Hogan's men empty out the gunpowder from a lot of cartridges inside the armoury. What did they do with their empties? It's not like a mound of empty cartridge cases on the ground wouldn't draw some suspicion is it? Yes, I am aware some options come to mind, e.g. putting the bullets back in and stuffing them back into the belts, but none of that is actually shown or talked about - LeBeau even chucks one cartridge over his shoulder, implying they are not very concerned about hiding their tracks.
Happy Birthday, Adolf - S1-E17
Character mistake: The artillery officer asks "Does headquarters expect a squad of infantry to replace experienced artillery men?" Hogan only offered "his detachment", and he's wearing a Luftwaffe uniform (and so is LeBeau). Why does the artillery officer get the idea that the "detachment" would be infantry, that is to say, ground forces (Heer) troops? To avoid confusion: Yes, the Luftwaffe did have infantry units, but those would be viewed by other branches as Luftwaffe guards primarily, not as infantry.
