Oil for the Lamps of Hogan - S1-E14
Other mistake: Anytime Hogan steals one of Klink's cigars from the back of the humidor, he takes the hinge pin out from the left of the box (camera's right). This time, he takes out the pin, got the cigar, and put the pin back in from just what looked like just left (camera's right) of center.
Happiness Is a Warm Sergeant - S1-E11
Continuity mistake: When accessing the tunnel entrance, usually the spot is in the middle of the side board that is tapped. Newkirk slaps the corner and post of the top bunk.
Top Hat, White Tie and Bomb Sights - S1-E10
Revealing mistake: When General Burkhalter has entered the camp and is stopped at the gate, the camera cuts to Hogan and the guys. Above the barracks, you can see the Desilu water tower. (00:15:30)
Top Hat, White Tie and Bomb Sights - S1-E10
Audio problem: When Schultz comes into Hogan's office with the pie plate, he starts talking about Klink. As Hogan puts his hand over Schultz's mouth to stop him talking, Schultz is cut off mid-word. The sound he made is heard there, and again at Klink's office, almost like an echo, when everything else said is heard in real time. (00:08:40)
Color the Luftwaffe Red - S4-E8
Revealing mistake: When the truck with Hogan and company pulls up to the Luftwaffe HQ, the camera pans to the right to look at Klink getting out of the side car. When the camera cuts back to Hogan and company, they shake as if the truck just stopped, but it can be seen that the truck was stationary.
Color the Luftwaffe Red - S4-E8
Other mistake: The telephone booth located by the Luftwaffe HQ appears to be one of the London police boxes.
Man's Best Friend Is Not His Dog - S4-E6
Other mistake: When referring to the barracks, usually Klink will refer to the buildings by their numbers (Barracks 2, barracks 3, etc.). In this episode, he calls the building "Building G".
LeBeau and the Little Old Lady - S3-E25
Continuity mistake: When Newkirk and Carter are playing Gin, Newkirk puts a card on his forehead so Carter can't get it. When he puts it on his head, it's about a quarter inch below his hairline. In the close up, the card is now at the hairline. In the wide shot, the card is again about a quarter inch lower.
What Time Does the Balloon Go Up? - S3-E24
Continuity mistake: When the British spy is trying to get to the camp, the area around him seems fairly lit, as at dusk, after the sun just set. When he glances toward the gates, the sky is black, suggesting night (the shot of the gate is stock footage). When the shot goes back to the spy, it's dusk again.
Continuity mistake: When Klink goes to leave his quarters to meet the plane, he doesn't have his familiar outer coat in his arm or on him. When he gets to the rendezvous point, he has it on.
Other mistake: When the head counterfeiter comes in, there is a sign on the barracks behind him that says "BARRACK 3." Two problems with this. First, Hogan and company are housed in Barrack 3. Second, there is not a Barrack building between Hogan's building and Klink's office building.
Nights in Shining Armor - S3-E8
Other mistake: In the end, Schultz tests the faucets, and they work correctly. When Klink goes to touch the faucets, watch the drain. The high pressure jet of water comes from it just when Klink is over it.
The Witness - S4-E23
Continuity mistake: In the beginning, the guys are listening in on Klink's office. The cup in front of Newkirk has four pencils in it. The colors from left to right are yellow, red, blue, and orange. After the camera cuts to Hogan and Kinch, the wide shot shows five pencils arranged yellow, black, blue, red, and orange.
Will the Real Colonel Klink Please Stand Up Against the Wall? - S4-E13
Audio problem: When Carter, dressed as Klink, approaches the staff car, Bruno the dog starts barking at him. Watch the dog's mouth. It doesn't match the noises at all.
Will the Real Colonel Klink Please Stand Up Against the Wall? - S4-E13
Visible crew/equipment: When Hogan opens the window, there is a reflection of the studio lighting on the top pane.
Revealing mistake: When Schultz is on the way out after giving the guys the news about the inspections and roll calls, you can plainly see that the background behind him is a matte painting. This is easy to spot because the building in the distance is lighter in color, and there are ripples in the fabric used.
Watch the Trains Go By - S4-E19
Visible crew/equipment: When Klink is by the fence acting busy and talking to Schultz, twice you can see the shadow of the camera on Klink's overcoat.
I Look Better in Basic Black - S1-E28
Revealing mistake: When Hogan, Newkirk and Lebeau are dressed as the three women captured by the Gestapo, demand the truck be stopped, the wide shot shows that the truck is already stopped, and shaken to simulate it stopping.
The Informer - S1-E1
Continuity mistake: In this episode, the doghouse that disguises an entrance to the underground is flipped up on end, and the separate floor is flipped up in the opposite direction. In all of the following episodes, the doghouse, and the floor, are one piece.
The Informer - S1-E1
Continuity mistake: In this episode, Burkhalter holds the rank of Colonel, Carter is a Lieutenant. In subsequent episodes, Burkhalter is a General, and Carter is a Sergeant.
