Continuity mistake: Near the beginning of the film when the sherrif is smoking a cigar and talking on the bridge, the cigar changes position every time the camera cuts between a close-up of him and a wider shot.
Continuity mistake: When the wishmaster freezes the cop, he's frozen to the point he can't move. Yet when the other officers arrive and are speaking to wishmaster, you can see him moving around in the background.
Continuity mistake: During the scene when they are trying to bring Mr. Leniog into the rear of the door we hear them trying to open the door from the inside, shaking it rather violently. From the outside shots we hear the door rattling but it's not moving at all like it is from the inside shots.
