Factual error: The tank used in the episode is not a tiger tank but an American M7.
Request Permission to Escape - S1-E32
Continuity mistake: While Carter and Klink's secretary are conversing, the waste basket Carter holds switches positions from up to down and back again.
Continuity mistake: Hogan and company use red painted gold bricks to replace the wooden stairs that they sabotaged. The steps after this episode should have been brick, but they went back to being wooden.
Suggested correction: This is technically correct; however, the series was set up to allow the episodes to be aired in any order; this is why it is always winter and some episodes do refer to other storylines and actual events/dates for episode storylines, e.g., Hogan's D-Day, which took place in June, not wintertime.
Reservations Are Required - S1-E15
Continuity mistake: Hogan dumps a bucket of water on Barnes and Davis each, to make it look like they were the ones who hid in the tanker. They get big wet patches on their uniforms from it, but aren't completely wet through and through - which is to be expected, after all it's just a small bucket of water each. After the next cut however, they are completely soaked like they went swimming.
Anchors Aweigh, Men of Stalag 13 - S1-E16
Revealing mistake: When the "Boat" is loaded on a "trailer", you can see that it has very little ground clearance. The wheels of the "trailer" actually are hidden behind the boards like on a parade wagon. The boat has no keel and no hull below its freeboard. Besides the question of how the boat got onto the trailer if it is practically built around it, there remains the question of how it is supposed to stay afloat without a keel or a bottom.
I Look Better in Basic Black - S1-E28
Factual error: When the SS guard is calling Sergeant Shultz after seeing the burning fuse, he addresses Shultz as "Sergeant", rather than the proper German word for Shultz's rank, "Feldwebel."
Suggested correction: "Hogan's Heroes" is an American television show produced for an English speaking audience. The whole show is shot in English! Did you expect Schultz and Klink to speak German and LeBeau to speak French?
I have seen MANY instances in the show where German characters are speaking actual German phrases (many quite accurately, by the way) and ranks of fellow German soldiers. When the German characters are addressing English-speaking characters in this American-made show, you do expect them to speak German-accented English, however, when German-speaking characters speak German to each other, one expects them to use the proper address and vernacular Germans would use and not mix in other languages. In this case, the SS guard did not know a lick of English when he was questioning some prisoners who were out their barracks, but addresses Sergeant Schultz as "Sergeant" rather than "Feldwebel." Furthermore, why aren't little things like buckets of water used in the show are labeled, "Water" rather than the German "Wasser"? Why isn't the list of rules tacked onto the barracks say "Forbidden" rather than "Verboten"?
The point is that when German characters are speaking to each other, it is assumed by the audience that they are speaking German and we are hearing an English translation for our convenience. In the world of the show, they are using the German term, but we hear the English equivalent.
Factual error: The guard outside Klink's office and the two Gestapo soldiers guarding the gold truck have MP38/40 and a Thompson submachine gun, but carry rifle ammunition pouches instead of the long ammo pouches that carried the 30-round magazines used by the MP38/40.
The Safecracker Suite - S1-E27
Continuity mistake: As Günther leaves the room, Klink touches his forehead and begins to sit down (or his knees are buckling, not relevant). After the next cut, he sinks down into a chair in a closeup. That same chair was behind Hogan before the cut.
I Look Better in Basic Black - S1-E28
Other mistake: When Hogan asked the girls if they wanted to try to escape to England, the one in "basic black" said that anything is better than being booked in a German prison camp for three years. How did she know when the war would be over?
The Flame Grows Higher - S1-E31
Visible crew/equipment: Toward the end of the episode, after the two women are taken out by the Gestapo, Shultz, Hogan, Lebeau, and Newkirk are standing having a drink. The camera goes in for a close-up on Shultz, there is a noticeable shadow of the camera on Shultz's coat, and right arm.
The 43rd, a Moving Story - S1-E23
Character mistake: When Klink explains the route of the trucks carrying the red cross packages to Kühn, he for once uses a map actually showing Germany. Unfortunately, the places he points to start near Luxemburg and track all across Germany. The spot he places Hammelburg at would be near Poznan in Poland.
I Look Better in Basic Black - S1-E28
Factual error: The American women the SS brings into camp claim to be entertainers having performed for troops. The series is allegedly set in 1942. Before June 6th, 1944 there were no allied troop concentrations in central Europe, certainly not in Germany, and very certainly none of a size and security rating the USO (or probably rather its predecessor organization, since the USO was founded in 1941 and would not have been fully operational yet) would send a troupe of female entertainers to.
Revealing mistake: When Le Beau holds up the gold painted brick and the "gold" brick, the ends reveal that they appear to be pieces of lumber. The ends seem to have grains consistent with lumber.
Request Permission to Escape - S1-E32
Character mistake: When ordering Schultz to finish cleaning his car, Klink salutes Schultz, his returning the salute with the garden hose in his hand leads to Klink being soaked. A salute is, except in rare circumstances, always initiated by the lower-ranking individual and returned by his superior, not the other way round. This rule is broken especially by Klink in several other places as well.
Movies Are Your Best Escape - S1-E8
Revealing mistake: When Schultz is talking to Hogan and Le Beau, the guard outside walks past. As he does, you can see three shadows from him revealing the studio lighting, rather than him really being outside.
Revealing mistake: In the close ups of Maj. Zolle, it can be seen that the spectacles that he has on have no lenses.
Other mistake: When the man goes to close the door, Newkirk gets a piece of plastic in between the door and the jamb to prevent the lock from engaging. But if you look closely, the plastic is above the lock, not stopping anything.
The Late Inspector General - S1-E4
Plot hole: At the beginning, the Inspector General instantly pegs the incidents Hogan's men enact as staged to defame Klink, and takes it as proof Klink is the right man to be put in charge of all POW camps in the Reich. Later, as Klink and he do their "final inspection", much less severe - and frankly, much less believable - incidents cause him to completely revise his assessment of Klink. Him believing Klink would be a pickpocket and compulsive kleptomaniac simply doesn't make sense.
Continuity mistake: When Hogan and the crew first see the silent airplane overhead, it has a twin tail. When shown up close in later scenes it has a single tail.
Top Hat, White Tie and Bomb Sights - S1-E10
Audio problem: As Schultz is complaining about Klink, Hogan puts his hand over Schultz's mouth, and you start to hear the canned laughter. When the camera looks at Klink, the sound Schultz made with the canned laughter behind it is repeated.
Suggested correction: I think that the tank in question is actually an M3 Lee.
It is an M-7 Priest, armed with a 105mm howitzer, not an M-3 Lee.
