Other mistake: When Conan gathers flowers to "take to the girl", the flowers that he is holding as he mounts his camel, are very long-stemmed, and dark purple in color. In the next scene he is riding the camel and the flowers he is holding are not only very changing color as another post indicated, but they are also very fake plastic / fabric flowers. In the same scene, Conan is then seen wearing a strong of flowers around his neck, those too are very fake flowers. (01:05:00)
Other mistake: The scene where Robin Ignico mentions Annie's new dog Sandy "but there's no bite in him," Lucy Stewart can be seen re-mouthing Robin's line.
Other mistake: When Sid committed suicide, the coroner brought him out of the office...not his room.
Other mistake: In the Ring Game, Flynn throws a shot that Crom catches and returns. When the shot hits Flynn's rings, it takes out the third and fourth ring. Problem is that any other time, the impact only takes out the ring that it hit. Close inspection shows a solid hit on the fourth ring only. The only explanation is that since Flynn continues and jumps the "gap" in the rings, this was a deliberate set up to bring the end to this sequence and move the movie forward.
Other mistake: When the hunter throws his cross-x at the witch's backside, the witch screams a second before it even makes a strike sound. And when he goes to pull the cross-x out in the far shot, there is nothing in her back.
