Other mistake: The Kommandant's building and the barracks appear to be only twenty to twenty-five feet apart, showing that this scene of Roll Call is in the studio. Otherwise, the outdoor shots are at the studio back lot.
Factual error: As the staff car comes up the street, there are a number of neon signs lit up, as well as store fronts. This is wrong as during the night in wartime Europe, such lighting would be dark to avoid night bombing.
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: At the end, Colonel Sitzer pushes Hogan away, calls for music, and puts his left hand over the microphone, with his right hand hanging by his side. A second later, his right hand is mid way up the stand.
When Klink is begging Hogan to trade places with him for fear of assassination, he says to him something like."I want to live til 80...all my family has lived til 80." Werner Klemperer, who played Klink, passed away in 2000 aged 80.
