This is the eleventh and final of eleven appearances Joseph Crehan makes in the series, each time playing a different character.
Given an uncredited bit part as a reporter in this show, Charlie Picerni is perhaps better known in the industry for his work as a stunt coordinator/director, as well as performing stunts and acting as stunt doubles for other actors. His work in Die Hard (1988) and the franchise that followed made him a star in the field of movie stunts. The actor who plays Lee Hobson in The Untouchables (1959) is in real life his brother.
This is the only appearance Wendell Corey makes in the series, playing a character in a political role. When he died in 1968, unlike the corrupt politician in this episode, he had put acting behind him and was serving as a distinguished and uncorrupted member of the Santa Monica, CA, city council.
This is the first of two appearances Carroll O'Connor makes in the series, each time playing a different character. His other appearance occurs in Bird in the Hand (1962). He is perhaps best known as Archie Bunker in the long-running '70s sitcom All in the Family (1971).
