At the very beginning, Schultz lights a cigarette for Carter. Schultz is standing right in front of the barracks door. When the camera changes to show people running out the door, Schultz is standing a few feet to the right of the door. Update: This sequence is shot in two passes, using cameras at two different angles. At the start, the angle is almost straight-on, facing the barracks, with the camera located to the left of the door. In the second pass, the camera is to the right of the door, at a much more extreme angle relative to the barracks. There are four cuts in the whole sequence (five segments), alternating the point of view. Segment one starts with Schultz approaching the door, and Carter coming out. Segment two is Schultz calling, "Halt!", and Cater sidling over to his left to draw Schultz away from the door. Segment three is Schultz searching for a match and lighting Carter's cigarette (Carter waves to the door to signal the other prisoners). Here, suddenly, Schultz is in front of the door. Segment four is Carter completing the wave, and the prisoners leaving the barracks. Now Schultz is back to the right of the door. Segment five is Carter handing the gun back to Schultz, going inside, and slamming the door to cause the snowfall. Here, Schultz is more correctly positioned to the right of the door when the segment starts.
The picture of Hitler on the wall giving the speech has no microphone hole in it, as there were in earlier and later episodes.
When the 'Happy Birthday Adolph' came out of the guns, there was one gun (number 6) that had a muzzle brake with round holes in it. All of the other guns did not have a muzzle brake.
Like the party banner which misspells Adolf Hitler's first name, the flags displayed when the gun crews attempt to fire at the Allied planes also incorrectly read "Happy Birthday Adolph".
When Major Keitel gave the range to the aircraft, he gave it as '1500 yards'. Germany was on the metric system at that time; he should have used meters instead of yards.
It appears that the 'phone line' that Kinchloe and Newkirk have tapped into above Newkirk's head is actually a power line. The 'phone line' above Newkirk's head is secured to the support on the pole by a glass insulator. The glass insulator is only necessary for uninsulated power lines. Telephone wires are insulated to prevent short circuits and crosstalk, and thus would not need a glass insulator.
One of the trucks has the steering wheel on the right. Normal German trucks would have the steering wheel on the left.
The stock footage of the American cargo planes that deliver the paratroopers are, in select spots, painted "International Orange." Tactical airplanes in wartime would not be painted as such.
In the scene where Hogan and Helga were kissing in Klink's office, there were shadows on the walls from 2 different angles. These were strong shadows from the production lights. There was a shadow from Hogan on the wall on the left, and a shadow from Helga on the wall on the right.
Major Keitel gave the range of the aircraft as '1500 yards'. This is 4500 feet. Heavy bombers, such as the B-17s shown, would not be attacking this type of target from such a low altitude.
The timing for the whole mission/raid is unworkable. First, Mama Bear requests intelligence on the German defenses in the area of a probing raid scheduled in 48 hours. Radio silence will start at 1500 hours (3:00 PM) the following day. LeBeau does the reconnaissance, but gets back almost two hours after radio silence (about 5:00 PM). That ends the first day. On day two, Hogan sets up the plan to disable the gun battery, and visits Major Keitel (commander of the gun battery). Hogan gets back from visiting the Major, and has Helga get the girls for a party the following night. Major Keitel calls Hogan and requests a prisoner work detail to clean up his base. On day three, Hogan and the work crew clean up the base and prepare for the party (and disable the guns). The raid occurs during the party. Based on the initial communication, the raid should have occurred at the end of day two, not day three.
Germany didn't have Palm Date Trees which bare the delicious fruit. Yet, behind Barracks 2 can be seen a huge Palm Tree. Spanish Catholic Missions and Missionaries brought these palms that originated from Egypt to California back in 1763.
One scene shows paratroopers jumping from C-119 cargo aircraft. The C-119 did not become operational until 1947.
When Klink is about to sit on the hat, the camera moves in for a closer look. You can see a shadow of the camera man at the bottom of the screen on the chair and Klink's pants leg.
In some scenes, there is a reflection in Klink's monocle from production lights.
At one point, it was said that there were 12 guns at the location. When the 'Happy Birthday Adolph' flags came out, only 6 were shown. No guns were heard firing. What happened to the other 6 guns was not stated.
The sign at the party says, "Happy Birthday, Adolph", spelling Hitler's first name incorrectly (Adolf).
After LeBeau gets back from his reconnaissance mission, it is too late to make their report, since Mama Bear went off the air at 1500 hours. It is highly doubtful that they would have proceeded with the probing raid without the information from Hogan, since they have no intelligence on the German defenses in the area.
Major Keitel never questions why Captain Hoganburg and his men are gone when the raid occurs, when he was supposed to be manning the guns in place of the Major's staff.
In the opening sequence, where Carter distracts Schultz, and Hogan, LeBeau, Kinchloe, and Newkirk leave the barracks, Carter waves to the door to signal they can leave. However, the door is not cracked open so it would be impossible for Hogan to see the wave.
In the opening sequence, when Carter distracts Schultz, and Hogan, LeBeau, Kinchloe, and Newkirk leave the barracks, Hogan makes so much noise when opening the door, that Schultz would have heard it. Newkirk at least closes it quietly, so as not to alert Schultz.
