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
Starring: Joanna Pettet, Rod Serling, Larry Watson, Matt Pelto
Continuity mistake: The shots of Doran from his left rear shows him a couple feet away from the wall while frontal shots show him backed up against the wall.
Rod Serling: For those of you who've never met me, you might call me the under-nourished Alfred Hitchcock.
Trivia: The closing scenes were shot through green-gold filters to give the streets a drab, hellish appearance. An appalled film lab technician tried to dye the sequence pink, and defied the director's order to "leave it green." NBC, the lab tech argued, would never accept those scenes because this was supposed to be color television. After demanding several re-dos, the director won the shouting match, the green prevailed, and NBC, apparently, never noticed.
