Audio problem: In the scene in the banquet hall, where the bad-guy is eating a carrot, he throws it on the floor. Subsequently, while chewing on the little bits he has left in his mouth, there comes a sound which is not a chewing-small-pieces-of-carrot sound, but a biting-a-piece-off-a-carrot sound. That sound was way too loud to have been produced by some little piece he had left in his mouth. (00:47:45)
