Crew or equipment visible: The ending credits of the "pygmillion" episode, shows a man's right arm (with short sleeved shirt) as he is walking on the driveway toward the camera, and then it/he is jerked out of the picture as he gets close to the camera.
Continuity: In a number of season one and season two episodes, location/establisher footage showed Jane Hathaway's first car, a 1962 Plymouth convertible, but in some cases the scene would immediate cut to a close up of her arriving in a 1963 or '64 Dodge.
