Factual error: Burkhalter refers to Jesse Owens winning the gold medals in the Berlin Olympics, and that Hitler left the stadium every time Owens was to be presented a medal. Truth was, Hitler left the stadium when another black man won the day before, and didn't snub Owens at all. In fact, Hitler wasn't in attendance the days Owens won.
Revealing mistake: During the main part of the plot, the guys are putting dynamite on each truck in the convoy as they fuel up at Stalag 13. It is supposed to be dark, (hence the reason the boys wear black) but there are shadows as if it were day. It's impossible for the driver in the following truck and the guard in The Tower to miss seeing the boys as they go back and forth to plant charges.
Visible crew/equipment: As Burkhalter is talking to Strauss and Klink in front of the office door, you can see the shadow of the boom mic moving over each as they talk.
Continuity mistake: When the man and woman from the underground meet Hogan at the Hoffbrau, they're taking off their outer coats. The man takes off a dark brown coat and drops it. Hogan picks it up, hands it to the guy who hangs it up. The man removes his dark brown overcoat revealing a tan coat. The next shot, he"s taking off the dark brown coat again, hangs it up and goes for beer.
Visible crew/equipment: As Hogan, Le Beau, Kinch, and Schultz talk at the car, the boom mic is reflected in the chrome and on the hood.
Factual error: In the rec hall where Klink is weightlifting, there is an advertisement poster for the Grindelwald region on the wall, which is in Switzerland. The German propaganda poured a lot of money into promoting the Reich's own recreational regions through the "Kraft durch Freude" program. With the war going badly, they especially wouldn't want a "Look how beautiful Switzerland is" poster in plain view of their troops every day.
Continuity mistake: When Klink sits down with Marlene, her hands alternate between being on his face to behind his neck and back between shots.
Plot hole: In his German uniform, Col. Hogan wears a number of decorations, among them the Iron Cross first and second class. When did he earn those if he has just been drafted for a suicide mission? After all he was not posing as a Wehrmacht soldier for a change but wore the uniform "officially". (00:17:00)
The Antique - S5-E12
Character mistake: Schultz states "In Hammelburg, they call me die Glitterzehe", which is a literal (but wrong) translation of the term "twinkle toes." That term does not exist in German, and even if it did, it would have to be GlitZerzehe, because the German word for twinkling is 'glitzern', the word 'glittern' does not exist.
Other mistake: The men are usually all wearing boots. When Carter goes up the ladder, it's clear that he has high-top sneakers on.
Continuity mistake: As Schultz marches in with the Kraut platoon, he reports to Klink. As he goes to stand at attention and report, the new tunnel section he's over collapses, and he completely disappears into the hole. The camera goes to a close up on Klink, then back to the hole, and you see Schultz standing in the hole and it's only chest deep.
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: All through the episode, we are in a snowy, wintry camp surrounded by hills and trees. The target Gen. Burkhalter points out however is a little shed on a flat-as-a-board prairie with not a flake of snow OR a single hill visible anywhere, and the brown grass of late summer. (Yes I noticed there are some mountains off in the distance. So not relevant for this mistake).
Other mistake: When the Heroes are outside talking, the camera focuses on Col. Hogan. Over his right shoulder you can see a hill with a baseball field's home plate fencing on top.
Other mistake: As Hogan and Kinchloe sit on the bunk to keep the trap door from opening, the secret switch to activate it is visible.
Continuity mistake: The whole operation is supposed to be at night, but when the original seven approach the gate to surrender, it's late afternoon, and very light.
Other mistake: As the boys are unloading the truck, one of the cases is WEIN (wine) , and marked with a 'Z' in the corner. In Season 4 Episode 22 "The Purchasing Plan", the boxes marked "Z" were boxes containing nitro glycerin for the underground.
Continuity mistake: In Klink's quarters, As Schultz and Klink talk, Klink asks a question and takes a bite of steak, and the fork is still up. After the angle change, the fork is suddenly missing.
