This is the only episode in which Sam Lane was played by Denis Arndt. In all of the character's subsequent appearances, he was played by Harve Presnell.
Traditionally, in the comics and most adaptations, Lois' father, Sam Lane, is a general in the U.S. military.
At the poker game, Lois calls "Seven card stud. High-low. First and last cards down. One-eyed Jack's and Deuces wild." Perry gives her a pained look. Old school serious poker players really detest unnecessary elaborations like high-low split pots or wild cards; some don't even approve of stud instead of draw. Lois, calling for an elaborate variant but failing to even declare openers, proved herself an amateur poker player.
Episode title is "Requiem for a Superhero". In 1956 Rod Serling's "Requiem for a Heavyweight" aired on TV and won both an Emmy and a Peabody Award. This helped Serling sell CBS on his idea for "The Twilight Zone".
According to the promotional poster that is briefly seen pinned to the side of one of the lockers in the fighters' locker room, the boxing event is titled "The Maulings in Metropolis".
