+ Are any of the actual Perry Mason cars around Today? Mike Bedard 4.16.15

Sightings: Distinguished Gentleman #1 plays the court reporter again. Submitted by Kenmore, 10/3/10.

The Pencil Mustache Man does double duty in this episode. He appears firstly as a court officer (standing and then sitting by the window—well, it’s been a long day) and later as a bystander at the lockers behind Addison Doyle. He may even be speaking with Distinguished Gentleman #1. Submitted by evelyne, 18 February 2011.

"Sasha Magaloff" appears in court on Perry's side wearing glasses, Submitted by BigBill767, Nov 11, 2016.
+ "Sasha Magaloff" is now known to be the actor Mitchell Rhein. Submitted by catyron, November 16, 2020.

The uncredited detective who discovers the ice pick appears to be Jeffrey Sayre, a bit player and background extra in many TV and film projects of the time. Sayre has three uncredited Perry Mason listings in IMDb, TCOT Shoplifter's Shoe (department store customer), TCOT Weary Watchdog (party guest), and TCOT Clumsy Clown (courtroom spectator). Here he has dialogue and appears in two scenes (he also helps unload the deep freezer), but is not credited nor listed in IMDb. Submitted by alan_sings, 8/4/2012.

Robin Hughes would later play the devil himself (and the title character) on The Twilight Zone episode "The Howling Man" (1960). Submitted by Wiseguy70005, 7/14/12.

Possible Goof: When Burger calls Ned Bain to the stand the judge asks "Is there a physician in attendance?" The judge's voice seems muffled as if he doesn't have a microphone and his voice is only picked up from William Talman's microphone. Submitted by Wiseguy70005, 7/14/12.
+ Actors at that time did not wear body microphones, especially in the studio where a large "Boom" microphone would be used instead. It appears here that the Boom mike was above Talman when the judge made his statement and they didn't bother to either re-do on camera or ADR (additional dialogue replacement) the judge's statement later on. The large microphone on the judge's desk is just for show as most props on a set. Submitted by Kenmore 8/5/2012
++ Sorry I wasn't clear, but that's what I meant, that the boom microphone wasn't on the judge. I know they didn't wear mikes and certainly didn't think the judge's desk mike was operational. Submitted by Wiseguy70005, 8/05/12.

Another possible goof: At 2057 on the DVD Harriet Bain's car (and license plate) are seen in a taxi driver's rearview mirror. However, the image is not reversed as it should be. Submitted by D. Tlougan 5/1/15.
Yet one more possible goof: When Perry enters JJ's apartment for the first time, he places a handkerchief over his right hand so as to not leave prints on the doorknob, yet when he enters the kitchen, he reaches crossbody with his unprotected left hand to switch on the light; as he leaves the kitchen, once again he uses his bare left hand to switch off the light. jfh 30May2019.
+ If you look close you can see Perry has his handkerchief in the hand used to turn the switch on and off. Kilo 6/13/2020.

Syndicated cuts: Mason and Harriet go to the Bain house and are met by Sylvia and Mason's introduction to Addison; Addison tells Mason about being charming and Mason warns him not to become involved with Sylvia; Mason asks Paul [actually, Della] about Dr. Gross's Criminal Investigations and Paul [Della] says [s]he sent for a copy; Burger's examination of Tragg on the stand; the taxi driver Miller's testimony.
+Additional Hallmark cuts: Part of Della and Harriet's conversation concerning Addison's attraction to Sylvia and her description of Sylvia being everything Harriet wasn't; a brief section of West trying to play the tape after Mason has erased it; Mason's first objection during West's testimony concerning best evidence and Burger's reply that he will introduce the tape after laying proper foundation. Submitted by Wiseguy70005, 7/14/12.
++ Additional MeTV cut: I had the closed-captioning turned on (Comcast) and the final visual scene ended with Della telling Perry that Harriet was leaving for London in a plane "in a hour", at which time the closing credits immediately began. Interestingly, as the closing credits began, the closed-captioning indicated an additional line spoken by Perry, asking if Harriet's plane was taking the polar route to London. [personal observation: It seems to me that MeTV is making a few here-and-there cuts not noticed before, up til now the cuts seemed to have been cutting fade-ins and fade-outs, making scene changes and commercial breaks more abrupt.] jfh 30May2019

+++ Many syndicated cuts omit a key scene about halfway into the episode that takes place in Doyle's apartment. Perry discovers a clue there (referenced in the wrap-up) that helps identify the murderer. Third_Generation_Fan 12/26/2020

Christian Nyby, the director of this episode, is famous for directing the 1954 Howard Hawks production of the science-fiction classic "The Thing." Submitted by Rev. Susie the Floozie, 10/18/12.

It's for you, Mr. Mason: A good secretary always knows where the boss is. This time Della reaches him at the Bain residence. Submitted by francis, 6/05/14.
+ This was only the second time in the first twenty episodes Della called Perry while he was away from the office. The first time was episode 13 when she called him at Paul's office. Of the 10 phone calls Perry received up to this story 4 were from Paul and two from Della. Added by H. Mason 10/2/14

Recycled newspaper: The copy of Los Angeles Chronicle being read by Arthur Best in the lobby of the Gilbert Hotel came from episode 8 TCOT Crimson Kiss. Submitted by H. Mason 10/2/14

Sponsored Items: I watched this episode on MeTV and was surprised to see the pictures of FOUR sponsored items show up during the closing credits (like in episode 7 and 240). The same FOUR items pictured at the end in episode 7 show up here. As I stated in episode 7, I could not figure out the First one shown, but Wiseguy70005 stated on 4/14/15 that the first one is actually "Sweetheart Soap" (I NEVER would have guessed that one, so thanks for the info! To me, the first letter looked like a "G" as in the word "Gourmet" and the product looked like a "bun"!). The Second was "New Blue Dutch Cleanser". The Third was "trend" (with a lower case "T"). The Fourth was "Beads-O'-Bleach". Submitted by mesave31, 04/19/15.

Hughes' story of having his orders changed was the subject of the episode "Signal Received" from the series "One Step Beyond". Hughes appears with series host John Newland in the final scene and talks more about his experiences. Submitted by Kenmore 6/04/2021.

This is the only PM appearance for Tina Carver who starred in the 1957 sci-fi horror film "From Hell It Came" playing the role of Dr. TERRY MASON...MikeM. 5/18/2018
