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: As the ambulance leaves the hotel, there is snow on top of the fenders and spare tire. Back at the truck, there is snow on the fenders, but not the spare. This would be impossible as at the speed driven, the snow would have blown off any horizontal surface.
Continuity mistake: When Hogan is talking to Kiegel, Hogan's eyes are level as he looks across the table at Kiegel. After Kiegel says "Not good enough!", the camera cuts to a close up of Hogan, and he's now looking up as if the Major is standing. A moment later, the Major stands and leaves.
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.
Continuity mistake: When the staff car with Leslie Smyth-Beddoes pulls in, Hogan opens the window to see who it is. As you look past Hogan, instead of a daytime backdrop, there is a black backdrop, and the wooden shutters are lit up as if it were daytime.
