In the introduction, when Alfred Hitchcock as the 'convict' in the police lineup tells the chief detective, "Wait a minute, sir. You've got the wrong man.", it's a nod to the title and plot of Hitchcock's recent film, The Wrong Man (1956), which had just been released less than two months earlier in December 1956 before the episode which was broadcast in February 1957.
One of the few episodes in which Alfred Hitchcock appears with other people in during the opening presentation.
The old man prisoner says during the lineup that he's age 49. The actor, Russell Collins, was 59 at the time.
