This episode reunites Wendell Corey with fellow Rear Window alumnus Raymond Burr. Submitted by billp, 15 November 2009.

Wendell Corey, whose later acting career was marred by alcoholism, seems to be in a constant state of inebriation (e.g. slurring of words, bleary-eyed expression) through the course of his appearance. He still manages to turn in a good performance, however, as a despicable murder victim candidate. Submitted by BobH, 21 December 2015.

Gloria Talbott, who makes her final of four appearances here on Perry playing Minna Rohan, will forever be known to sci-fi fans as the woman who Married A Monster From Outer Space in the 1958 movie. Submitted by PaulDrake 33, 16 December 2009.

Paul Brinegar makes the second of his two Mason appearances, the first being the very minor role of Tom Sackett in the 1958 episode, TCOT Sun Bather’s Diary (#17). In the intervening years, he appeared as trail cook George Washington Wishbone on Rawhide (1959–65). His characterization of Jason Rohan is pretty much a reprise of the Wishbone persona.

+ Brinegar coincidentally happened to be in the Alfred Hitchcock Presents episode that aired last night - he was in three of the latter, so there are six possible combinations - and while, by itself, this is just an interesting bit of trivia, that he is just one of several persons for whom this has happened illustrates well the type of peformer the made PM "work": character actors who filled up the background of 50-60's television. Notcom, 101922.

If Wikipedia has their birth dates right, Paul Brinegar was only 10 years older than Hal Lynch, who plays his son, Matt. That's rather precocious fatherhood indeed! I was motivated to check their respective ages by how mature Matt looked. Submitted by JazzBaby, 6/27/2019.
+ Adding to the absurdity, at one point he remarks on "our thirty years of marriage": Gloria Talbott was all of 35 years old here...and didn't look a day older. Notcom 100521.
++Actually, he said "our two years of marriage." Apofisu 3/7/2023

Perry once again gets his coveted on-street parking space right in front of the courthouse! ;-> Submitted by mesave31, 03/12/15.

And, once again, enroute to the courtroom he loses his pocket square and gets a haircut! Oh, and what happened to his Lincoln? DOD 05/07/20

This is the only PM appearance for Danielle De Metz, who was born in Paris in 1938...MikeM. 4/6/2017

When Harry Lannon asks Della, at Klee's dinner party, whether she's enjoying her glimpse of the hoi polloi, is that a joke or ignorance on the part of the scriptwriters? Hoi polloi (no 'the' needed, as hoi is the determiner in Greek) means the common people, the unwashed masses. By the way, could that dinner party be any more unpleasant? Submitted by JazzBaby, 6/27/2019.
+ I have to empathize with the writers getting that wrong. It was decades before I found out what hoi polloi really meant; I can only guess that I associated it with "hoity toity"? To this day I have to make a conscious effort to remind myself that it means the opposite of what first comes to my mind. OLEF641 10/5/21
