Audio problem: When the burning USS Haynes is about to ram the disabled submarine, two Germans open fire on the destroyer with a deck-mounted Oerlikon autocannon. However, the sound of the cannon firing heard in the movie is far too slow to match the real thing, and in a segment where the cannon's muzzle flash is seen, it flickers far too quickly to accommodate the slower reports.

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.
