Sightings: A trio of regulars makes an appearence in this episode. As Hamilton Burger has Mr. Grant on the stand, we can see the Distinguished Gentleman #1 sitting next to the guard by the main entrance. And a subsequent close-up of Bert Nichols looking on shows both Pencil Mustache Man and Little Old Lady #1 sitting behind him. Submitted by Kenmore, 9/12/2010.
+ Quiet Old Man #2 is also in the gallery on the defendant’s side, while “Miss Carmody” and “Sasha Magaloff” are sitting together on the prosecutor’s side. The elusive Distinguished Lady #1 also appears on the prosecutor’s side in some shots (but not others), along with Little Old Lady #2. Quite a collection of favorites from the Who Is That? page!

+ "Sasha Magaloff" is now known to be the actor Mitchell Rhein. Submitted by catyron, November 16, 2020.
+ Distinguished Gentleman #1 makes an even earlier appearance. At then end of the workday, as Bert Nickels comes out of Fallon Paints, the Gentleman, sporting a hat, scurries down the stairs behind him—obviously anxious to get home. Submitted by gracenote, 6/3/2011.

Location: About 4:15 minutes into the episode Paul pulls his convertible around to Fallon Paints. What he is actually doing is driving around the studio where Perry Mason is being shot. In reality, Paul enters the scene from 1000 N. Seward and hangs a right onto 6600 Romaine. If you compare the Google street view to the episode you will see the exact same windows, 4 grooves in cement between the windows. You can even see the exact window pattern on the Seward Street building behind him that has the giveaway “Studio” signage. The square block Hollywood Center Studio still exists, and its history is covered in other episodes on this wonderful website. Lastly, the tarp over the building by the entrance was probably to cover studio signage they couldn’t remove. Submitted by Eric Cooper, 20 May 2011.

Character Names: We learn early on that Mrs. Temple’s first name is Agnes. Submitted by gracenote, 6/3/2011.

Uncredited Actors: When Ray Collins answers the door at the crime scene, Sgt. Brice (Lee Miller) and a uniformed police officer (Robert Wegner) are busily working and conferring in the background. Submitted by gracenote, 6/3/2011.

In the final scene Perry states he believes in what Judge Learned Hand (1872-1961) called the “eventual supremacy of reason.” Judge Hand stated, “I believe that the community is already in process of dissolution where each man begins to eye his neighbor as a possible enemy, where non-conformity with the accepted creed, political as well as religious, is a mark of disaffection; where denunciation, without specification or backing, takes the place of evidence, where orthodoxy chokes freedom of dissent; where faith in the eventual supremacy of reason has become so timid that we dare not enter our convictions in the open lists, to win or lose.” Submitted by Steve Fox, 4/18/2020
