Location: The early scene where Perry and Paul walk down a ramp to a dock on their way to the Blue Nymph sailboat was filmed near the Alamitos Bay Marine Bureau building. See here. Submitted by D. A Supernaw, 3/17/2005.

Sightings: In the middle of the courtroom gallery sits Quiet Old Man #1. Submitted by gracenote, 3/25/2011.
+ Distinguished Gentleman #1 peeks in between a blonde lady and Pancho Morado as they make a bet. He moves aside and continues to stand next to her as the two gamblers play. The Gentleman shouts, “He got ’em! Got ’em all!” Then he says, “Come on, pay up, Pancho!” And he laughs with another spectator. This may be the first time we ever hear him speak!!! Submitted by gracenote, 3/25/2011.
++ Actually, no -- we have heard DG1 speak before, and we even know his name, from TCOT Wintry Wife, #112, where he played a sales clerk and got a credit as Rudolph Salinger. (Thanks to Bill767 for this discovery.) There may be another instance, arguably and sort of, where we get a glimpse of someone who looks like DG1 from behind, and is laughing at a joke in a bar during TCOT Melancholy Marksman. JohnK, 26 January 2018
+++ Rudolph “Rudy” Salinger (Distinguished Gentleman #1) is listed at IMdb. He deserves a listing here s "uncredited actor," a step above "sightings." But since he had a speaking part in this episode, he should have received a credit. Submitted by catyron, DG#1's #1 Fan, September 13th, 2021.

Star Trek Alert: Three actors in this episode will appear in Star Trek roles. Stanley Adams was the sketchy, but loveable interplanetary trader, Cyrano Jones, who famously introduced tribbles onto the Enterprise and into our cultural universe. Dick Geary appeared as a red shirt, an Andorian, and a stunt man in three Trek episodes. Garland Thompson appeared in two original series episodes, "The Enemy Within" and "Charlie X." Submitted by MyFavoritePolarBear, 11/23/22.

Uncredited Actors: Don Anderson plays another (silent) double role in this episode. In the final courtroom scene, he is a spectator in the front row of the gallery, and in the last scene at the La Playa Bar & Motel, he is a background bartender. Submitted by gracenote, 3/25/2011.

The new season starts off with Ray Collins in the credits, but his character, Lt. Tragg, is absent again. Submitted by gracenote, 3/25/2011.

Through that remarkable transformation of the time-space continuum known as Daily Syndication we have David Macklin appearing less than two weeks after his last performance (Simple Simon), whereas in reality the appearances were separated by almost six months. Further testing our faith in the illusion of theatre is the fact that - at just eighteen* - he's actually younger than his character is probably intended to be...a novelty for PM (or many shows of the period). Submitted by Notcom, 041916.*IMDB has since upgraded his age to 23 in 1964 (who knows where it will end up, but like General Franco, he's still dead.) edited 072121

David Macklin seems miscast as a lobster trapper with the clean cut looks. Submitted by Perry Baby, 10.17.16

Location: About 19 minutes in there is a quick shot of the historic Hall of Justice on the corner of Temple and Broadway in Downtown Los Angeles. It was badly damaged in the 1994 Northridge Earthquake. Submitted by Eric Cooper, 12 August 2011
+ Closed for repairs after sustaining extensive damage in the earthquake, the Hall of Justice reopened in October 2014 following a $233 million renovation. Check out this story on the renovation, and this one to find out more of the building's history. OLEF641 7/21/21
++ If Harwell Pitkin had been an architect: Among the participating architects were Octavius Morgan, Reginald Johnson, Edwin Bergstrom, David C. Allison, Myron Hunt, Elmer Grey, Sumner Hunt, and Sumner Spaulding. Yes, this building just has ESG's imprint all over it!! Notcom, 072121.

Location: The finale takes place around historic Echo Park. It has been a favorite film location starting with Laurel and Hardy and Our Gang. Chinatown, Kentucky Fried Movie and even Gilligan's Island shot scenes there. Perry and crew drive around the lake in his sweet ride then take the nearby onramp onto the Hollywood Freeway when Della spots the missing girl. Submitted by Eric Cooper, 12 August 2011
+ Pretty lucky that Della has super-sharp eyesight. Submitted by catyron, June 15th, 2018

Names 1: This was the ninth time actor Charles Irving appeared as a judge and called Judge Blanchard. In episode 173 TCOT Golden Oranges he was given the name Judge Stanley. Submitted by H. Mason 4/4/15

Props It appears the model used for the murder reenactment is the Eldon Racing Sloop a popular toy of the period ("Popular", in this case meaning I had - and still have - one.) Brought into court by Notcom, 041916.

This is the only PM appearance for Claire Wilcox who, like Raymond Burr, was born in Canada...MikeM. 1/23/2017 Young Claire Wilcox had a fairly auspicious start as and actress in the Tony Curtis-Suzanne Pleshette movie 40 POUNDS OF TROUBLE in 1961. Unfortunately, her career did not last beyond her mid teens. Steven Blackwood 05/18/2022.

This is the first of three PM directing credits for director/producer Richard Donner, who went on to direct Superman and Superman II, and also Lethal Weapon 1 thru 4. He is married to producer Lauren Shuler and they run The Donners' Company...MikeM. 1/27/2018

Correction Richard Lester, of Help and A Hard Day's Night fame, took over direction of Superman II when Donner fell out with the producers. Donner's footage was later released on DVD as Superman: The Richard Donner Cut. Lester also directed Superman III. Personal note: I met Lester at the DC premiere of Superman II. Submitted by JazzBaby, 05/10/2019.

In "The Perry Mason Book" author Jim Davidson lists 111 North June Street as the filming location of the Blake residence. If you Google search this address, you will find that it's a Los Angeles historic landmark known as the Wolff-Fifield House. It is located about four miles directly west of Echo Park, where Perry and his passengers start their search for the child and the lady who took her...MikeM. 6/4/2018

Both Otto Kruger and Mike Mazurki appeared prominently in the 1944 film noir classic "Murder, My Sweet," starring Dick Powell as Philip Marlowe and arguably the best of the many movie adaptations of Raymond Chandler's Marlowe novels. The first shot of Mazurki, as reflected in Marlowe's dingy office window, is particularly memorable. Submitted by BobH, 7 June 2018
+ I just watched "Murder, My Sweet" (May 2019) and learned from Wikipedia that Mike Mazurki earned a law degree and practiced law, but gave it up to earn ten times more as a professional wrestler. He also played pro football and basketball. JohnK, 14 May 2019

This is the only PM appearance for Stanley Adams, who is quite famous to Star Trek fans as Cyrano Jones from "The Trouble With Tribbles". TriviaSleuth, 8/30/2019

When Perry and company are entering the 101 freeway on-ramp near the end of the episode, I think they are driving on the northbound ramp from Alvarado St. and then look up at the Rosemont Ave. overcrossing. However, when Della gets out of Perry’s Lincoln convertible to save Button, I believe they moved the shot down to Bonnie Brae St. which also crosses over the 101 and ends at Bellevue Ave. The large background houses on Bellevue are still there, but largely obscured by trees now. As for the reference by someone to Button’s large Tudor style house shown at the beginning and end of the episode of 111 N. June St., I believe that is correct. When I first saw the property, I guessed it was in Hancock Park and indeed it is. It looks much the same today and well maintained. MikeH 03/23/22

Julie Adams and Mike Mazurki also appeared in TCOT Deadly Verdict. Submitted by Steve Fox, 2/5/2023

Ed Nelson and Alan Baxter also appeared in TCOT Left-Handed Liar. Submitted by Steve Fox, 1/6/2024

Mind the Gap Otto Kruger was almost 79 here. While that is not the oldest appearance by a performer, nor even by a male - Francis Bushman and Estelle Winwood were both born in 1883; he would appear in 1964 (81), she in 1966 (83) - I believe it is the widest disparity in age between performers...almost 70 years seperated him from Claire Wilcox (and lest one wonder, Sara Taft was only 69 in TCOT Borrowed Baby).
