Anomaly: Walter Burke, listed as “Man,” is called Mr. Adams. Contributed by Tom Rankin, posted by daveb, 12/21/2007.
+ This is the fifth, and obviously last, Perry appearance for Walter Burke. jfh 13May2020.
++ Burke, along with H.M. Wynant, has the distinction of having played suspects and prosecutors in various episodes. DOD 05/13/20
+++ If Walter Burke had been 6’3” he would have been a major star. A wonderful actor. (I may have made a similar comment on another PM episode page. If so, well, I mean it twice.) Submitted by Rickapolis 06/28/23
Goof: As Lola Stanley gets in her car in the Globe News parking lot, a sticker with the CBS Eye logo is clearly visible on her windshield. (However, when she parks in front of a print shop, it is gone; perhaps someone caught the mistake.) Submitted by gracenote, 6/16/2011.
+ Something is still in the corner of the windshield. Perhaps the darker lighting makes it more difficult to see, or perhaps someone did obscure the logo. But why does Lola need to go to the printing-duplicating company to get copies of the documents? The people there are using just a small desktop copier to make the copies. By 1963, Xerox (per its history) for example was selling desktop copiers, so why wouldn't an international organization like Globe News have one accessible to a secretary like Lola in its Los Angeles office?

The Copy Shop set again: The copy shop (interior set) is a redress of the San Carlos Camera Shop from TCOT Positive Negative (or vice versa) down to the mailbox on the right and a boxing poster on the wall next to the shop. They were saving time and money. Submitted by Perry Baby 2/13/17
+ Good observation, PB. JohnK, 27 February 2018
+ + Dang, they didn't even wait a week! I transcribed what i could decipher of the words on the boxing poster on last week's episode. Submitted by catyron, August 18th, 2018

The House and Staircase Set: Also, and this is no surprise, the rich house seems to have not changed at all from TCOT Positive Negative. With the series coming to an end they must have been in a rush. JohnK, 27 February 2018
+ Other than Perry's office, that house set, with its distinctive staircase, is the most used set in the series, appearing in dozens of episodes over the years. DOD 4/12/18

The Menorah Mailbox is still affixed to the outside wall of the house. See details about this unexpected piece of Jewish decor in TCOT Positive Negative and TCOT Fanciful Frail. Submitted by catyron, August 18th, 2018

Sightings: The ever-present Pencil Mustache Man listens with rapt attention to the opening statement of the D.A. during the trial. Submitted by gracenote, 6/16/2011.
+ The young brunette also seems to be in gallery sitting near the Pencil Mustache man. Submitted by Perry Baby 2/5/14

Perry once again gets a coveted on-street parking space right in front of the courthouse...BUT this one is different than the one I am used to seeing as it has no traffic jam in front (pretty much clear streets are shown, a novelty I'd imagine <LOL!>!) AND Perry goes up the court house steps walking "away" from the camera. Submitted by mesave31, 03/18/15.
+ And, once again, he loses his pocket square en route to the courtroom. DOD 05/13/20

This is the last of 23 PM appearances for "Judge" Willis Bouchey, who was one of movie director John Ford's stock players. In a 1962 John Ford classic western, Willis Bouchey delivered the final line... "Nothing's too good for the man who shot Liberty Valance."...MikeM. 4/18/2018

West Bend Thermo-Serv: the West Bend Thermo-Serv carafe and one cup can be seen in Perry's office. Submitted by catyron, August 18th, 2018

Della comes thru in the clutch and with it !! Yes, she had her dinner ruined by a drunken boor, and then had to help render first aid, but when the time came to fetch some ice, she still had the presence of mind to take her purse with her to the kitchen...That's our girl !! Notcom, 051819.

Steve Drumm's Mysterious Filing System: Apparently, in Steve's alternate universe alphabet, file cabinet drawer S-T comes right after U-V and immediately before W-X. See last scene. With that kind of record keeping, no wonder he keeps arresting the wrong guy. OldDave, filed 5/21/20

The same cabinets appear in Shine’s office, and in seemingly random order. DOD 05/27/21

Location: The Globe Syndicate exterior shot is the old First Federal Savings & Loan Building at Hollywood and Highland. This handsome midcentury building didn't make it to 30 years old. It was built in 1959 and demolished in 1998. The Hollywood and Highland Center was later built on this site. From 1902 to 1956 it was the site of the legendary Hollywood Hotel.

A Bad Week: Pat Priest (aka Marilyn Munster) had a week in which the last episode of The Munsters aired on Thursday (12 May 1966) and her last appearance on Perry Mason aired the following Sunday (15 May 1966) in the show's penultimate episode. Her acting jobs were mostly TV guest spots after that, and by 1976, her show business career was limited to the nostalgia circuit. And Marilyn never did get a boyfriend. Submitted by Vladimir Estragon, 1 September 2020.
+ Just reading the Wikipedia article about Pat Priest and discovered that Pat's mother "Ivy Baker Priest (September 7, 1905 – June 23, 1975) was an American politician who served as Treasurer of the United States from 1953 to 1961 and California State Treasurer from 1967 to 1975." jfh 27May2021
