Audio problem: After the part where Johnny Depp finds his bookstore friend dead, he gets back in the cab. After driving for a while, he tells the cab driver to pull over to the phone booth. The cab driver says "No problem, sir" but you can see the cab driver's lips in the rear view mirror, and they never move.
Audio problem: Right after Max and Tom watch the two fake snuff films, Max mentions the record company's lack of interest. At one point his lip movements don't seem to match his words. (00:50:35)
Audio problem: Near the end of the movie, when Ichabod gives the horseman his head back, in one shot, the horseman has his sword in one hand, and in the next shot he puts his head on with both hands; yet we do not hear any sound of him either dropping his sword or re-sheathing it.
Audio problem: When Paul goes to Moore's house after Moore is released, it is implied that classical music is playing really loudly in Moore's house. When Paul breaks the door down, the music is still playing and the turntable is spinning in the foreground, but the needle is already at the end of the record.
Audio problem: During the scene right after Anton runs into the scarecrows in his house only to find out they are his deceased mom and dad, you see him run out to his porch and begin throwing up into his bushes. You can hear the sounds of liquid hitting the bushes, but you see nothing coming out of his mouth (there is enough light in the film to determine this).
