Visible crew/equipment: At the beginning of the episode, Jeannie is talking on the phone by the stairs and her sister is hiding behind the banister. Her sister stands up for a moment and shows her full face, revealing that it is actually Barbara Eden's stand-in wearing the green costume.
Visible crew/equipment: When Jeannie is swinging outside on Major Nelson's patio, the top of the soundstage and the ropes holding up the backdrop are visible when the camera switches to a low angle. A moment later, it is visible again, but only for a second. (00:09:40)
