Revealing mistake: As Sharsted enters Gingold's apartment, he enters directly from the sunlit outdoors. The interior shot of Gingold's does not show the outdoors when the door opens, but a darkened interior movie set.
Night Gallery (1970)
1 revealing mistake in Camera Obscura - chronological order
Starring: Joanna Pettet, Rod Serling, Larry Watson, Matt Pelto
The Cemetery - S1-E1
Continuity mistake: From the inside view of the window the Hendricks gravestone and the family name is visible on it. From the outside view of the window the gravestone and the Hendricks are facing away from the window.
Rod Serling: Good evening, and welcome to a private showing of three paintings, displayed here for the first time. Each is a collectors' item in its own way - not because of any special artistic quality, but because each captures on a canvas, and suspends in time and space, a frozen moment of a nightmare.
Trivia: The scene of the spooky castle on the rocky shore was used in episodes of "Gilligan's Island" featuring Vito Scotti as mad scientist Boris Balinkoff.
