Audio problem: In the first fight Conan has in the pit, his opponent starts smashing him brutally, to which Conan first responds by moaning in pain, but his mouth doesn't open and his face doesn't show the corresponding pain.
Audio problem: When the wizard arrives with weapons and armour, he is about to trip and mumbles out loud, but his mouth doesn't move. Neither does Subotai's when he asks him, "Hey, old man, where did you get this stuff?" (01:45:25)
