Visible crew/equipment: During the scene when Lou Costello is reading the narrative on Count Dracula we see the coffin door open and the candle on top of the box starts to descend. By the angle of the coffin door the candle would have easily fallen to the ground. If you look carefully you can see a thin black cord attached to the candle.
Visible crew/equipment: During the movie whenever Bob Hope is pulled off the wagon by his team of horses you can see a board leaning against the wagon that was used to help the stunt man when he was pulled off the wagon.
