Continuity mistake: Klink comes out with the "insurance policies" in his hand. They are lying beside each other, with a little space between them, and tilted in one position in his hand. When the camera goes into a close up, they are touching, and in a different position.
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)
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 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.
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.
Continuity mistake: In the tunnel, Hogan lays out the plan. The arms of the man next to him goes from crossed to by his side between angles.
Six Lessons from Madame LaGrange - S5-E22
Continuity mistake: When Hogan is talking with Lily Frankel before the double agent comes over, Hogan is lifting his beer. When the camera goes to close up, he's lifting it again. Also, in the long shot, the beer is down about three quarters of an inch from the rim. In the close up, the beer is nearly full.
Continuity mistake: When Klink sits down with Marlene, her hands alternate between being on his face to behind his neck and back between shots.
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: When Klink is "taken hostage" in the barracks, he is in his tunic only. Later in the car he has his overcoat on. He was supposed to be kidnapped, he could hardly ask Hogan to let him slip into his office for his coat.
