During Hitchcock's closing remarks at the end of the show, he's advanced on by a slender figure, in tights, with a very strange head. The head is an unused design for the aliens in "It Came from Outer Space." This seems to be its only appearance on screen.
Christopher Lee later admitted coming to Hollywood with the wrong impression that he would be directed by Alfred Hitchcock himself. Though he was never even properly introduced to Hitchcock during the filming of this episode, he felt very satisfied by the experience.
