Corrected entry: When LeBeau goes to get out under the wire, he raises an entire section of the wire on the inner and outer fences to do so. It can be seen that there is a bar on the bottom of the sections that he raises that suggests the sections are totally framed for the purpose.
Corrected entry: In the very beginning, the prisoners are all in formation for a count. Shultz completes the count at 15, reports it, and Klink calls Hogan over to talk. This leaves 14 in formation. Hogan says "Smoke if you have them". Unbeknownst to Klink, the men are in an arrow formation to point the way to the bridge for the bombers. The aerial shot from the planes shows at least 25 lighters lit. Where did the other 11 guys come from? With Hogan, his barracks only had 15 men who would've been in on it.
Corrected entry: When the Inspector General walks toward Klink's office, he falls into a fake tunnel section. As he goes down, he has his outer coat over his shoulders. When the shot cuts to him in the hole, the coat is missing without having fallen off. After he is out, the coat is returned.
