Visible crew/equipment: An angry aspiring home buyer tosses a tomato inside the office of Fakrash and Ventimore, but the rancid veggie boomerangs on him when the genie summoning his powers reverses the flow of time causing the tomato to fly where it came from. Well, that's the idea, while in fact you can see a literal stagehand actually throwing the tomato in the actor's face. (01:17:55)
Continuity mistake: In the padded cell, the shadows cast by both characters keep changing position depending on the camera angle. (01:20:00)
Continuity mistake: At the hearing, Fakrash starts flying around the room (with a terrible special effect). The men at the prosecution table lean forward to look at what is happening; their arm position changes between shots. (01:23:15)
Continuity mistake: When the genie waves his hand and shrinks the inquiring committee, the pens on the table change position. (01:24:25)
Revealing mistake: When the genie (Burl Ives) moves the fire plug you can see a bracket holding it up and running down to a track beneath it.
Factual error: Fakrash is a genie who served under King Solomon and he himself says that he's been imprisoned for 3'000 years. Yet the whole aesthetics of his clothes, decoration, architecture is the stereotypical Arabian Nights one, which would be several centuries posterior to his times and almost as foreign to him as the present day one.
Other mistake: Mrs Kenton and Sylvia can't get into the study where Mr. Kenton is; there is no reason why the door would be locked. A mule can't lock it with a key and there is no debris or furniture to block the door. Harold opens it just fine from the inside without operating any particular kind of lock.
