Wendell Muse does his magic fire act twice and the same audience reel is played both times.
When Sabrina is first tied to the chair, she is wearing open-toed sandals. Later, when the fire starts, she's wearing closed shoes. When she's rescued, she is wearing sandals again.
When Kelly, Kris and Bosley leave the The Magic Castle to rescue Sabrina, the occupants of Kelly's car are clearly two male stand-ins with lots of facial hair.
When Bosley is performing at the Magic Castle as Zolton, Kris is his aide. When she holds Thomas Romero's driver's license up to the camera, the photo of him was taken outdoors in sunlight.
When the conceited magician performs the glass wine trick for Kelly at the restaurant, when he tries to distract her with the red foulard, it is very obvious from the chosen camera angle, that he put his right hand inside his hunter green suede jacket pocket to retrieve the filled glass wine.
