Audio problem: Landa enters the farmer's house and talks to the girls but a side angle shows his mouth not moving, despite sound coming out. It only starts moving when he says the word 'Monsieur'.
Audio problem: When Guido knocks the flower pot from the window sill and it breaks on Rodolfo's head it looks and disintegrates like wood but sounds like terracotta. (00:09:30)
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Audio problem: In the scene where James "forgot [his] gloves down there", the sound from the detonation just before that is incorrectly in sync with the explosion. Given that they are a distance away from the blast itself, what should happen is you see the blast first, then hear it say about a second or more later (based on the estimated distance). (00:48:50)
Audio problem: After Gabriel shoots Tavington, he walks over to finish him off with his knife. He tosses it up in order to change his grip. When he does so, we hear metal scraping against metal, but he tossed the knife through the air, so it could not possibly have made that sound. (02:08:05)
Audio problem: When Sydney is listening to an American radio report during dinner, he says "I can't eat," but his lips aren't in sync with the words. (00:30:15)
Audio problem: When Pavlov is speaking with the doctor, we hear him finishing a sentence with "say, a doctor, perhaps" but his motionless mouth and jaw show he isn't speaking at all in the side shot. (00:19:00)
Audio problem: Strasser arrives at Rick's and a woman is playing a guitar while the band behind plays all kinds of instruments, but just the piano is heard. It looks quite ridiculous. (01:09:29)
Audio problem: When Strong is running away from Norah he passes the Sgt. The screams he is making are overdubbed as his mouth isn't moving. (00:57:45)
Audio problem: When Norm tells the crew about the SS Battalion, Coon throws his wrench into the mud. However, a metallic sound like a wrench hitting concrete is heard. (01:29:10)
Audio problem: The Sergeant is calling "Sunrise 6" on his radio hand mic, then tucks away the mic to scan the mountain with binoculars, but his voice is still calling Sunrise 6.
Audio problem: Towards the end Fraulein Rahm sends a child towards the Americans after pulling the pin on a grenade attached to him. He runs offscreen but no explosion is ever heard.
Suggested correction: So the grenade was (thankfully) a dud. Considering they were wearing paper uniforms, it isn't unreasonable to assume they didn't have the highest quality equipment.
Audio problem: When the movie begins and the choir sings, they're out of sync. After the shot of the Asian women on the benches the audio and the song are now out of control. Check the second boy to the left of Jim. He's absent minded and moves his mouth without control.
Audio problem: When Tristan returns the second time he is driving horses along, shouting loudly, but without moving his mouth. (01:19:35)
