Audio problem: In the scene where the Prince meets up with Leonardo da Vinci for the first time and notices that his guards have found him, he says 'Oh, I can't believe this'. His mouth isn't in sync with what he's saying.
Suggested correction: Firstly, the closed captioning reads, "God, I don't believe this." Second, Henry actually says it twice - the first time his mouth IS in sync with what we hear, but then he mouths under his breath "I don't believe this," again, in annoyance with the situation.
I am watching the scene right now, and his mouth really isn't in sync. In order for him to say the word "believe" (even in mumbled form), he would have to move his mouth to form the "b" sound, and he does not at that point.
Audio problem: When Bud is yelling at his sister in the school hallway by her locker, she complains about girls not being happy in poodle skirts and sweater sets. When the camera's point of view switches, her mouth is still moving even though she's stopped talking. (00:37:00)
Audio problem: In the Middle-Age, when Jacqouille is stealing clothes in the tailor shop, the saleswoman says to Jean-Pierre, with the voice of Jacquouille "Qui es-tu, demoiselle?" (Who are you, miss?).
