Chuck Hamilton, as the Postal Inspector, makes his first of four appearances on Perry in this episode. Even though Mr. Hamilton made four appearances, this is the only one in which his name appears in the credits. Mr. Hamilton was born in 1903, and of this date is yet alive. Mr. Hamilton holds the present record for oldest alumni of the Perry show at 106 years of age. Submitted by PaulDrake 33, 6 August 2009.
+ NOTE: Chuck Hamilton died the day before Christmas, 1978, at age 75. Submitted by cgraul, 11/3/2011.
+ NOTE: According to the IMDb web site Mr. Hamilton appeared uncredited in nine PM episodes. The last one was TCOT Scarlet Scandal in 1966.

Stuart Erwin makes his first of four appearances here playing Austin Durrant. From 1950 until 1955 Mr. Erwin starred in his own sitcom The Stu Erwin Show aka The Trouble With Father. Stuart Erwin was a long time actor who, believe it or not, was nominated in 1937 for an Academy Award in the supporting actor category [The movie for which he was nominated was Pigskin Parade. jfh 19Oct2018]. He lost out to Walter Brennan for Come and Get It. Mr. Brennan was also the star of an early television sitcom The Real McCoys. Submitted by PaulDrake 33, 24 November 2009.

Sightings: Once again, the Little Old Lady in a Hat appears. As Hamilton Burger questions Lt. Anderson, we see her sitting in the back row during a cutaway of David (Gerd Helm) & Austin Durrant (Stuart Erwin) as they watch from the gallery. Submitted by Kenmore 9/13/2010.
+ Distinguished Gentleman #1 is also observing in the courtroom today. Read more about him and other regulars on the Who Is That? page. Submitted by gracep 12/1/2010.

This episode makes the fourth appearance of Karl Held as David Gideon—which he will repeat another five times, for a total of nine. Submitted by gracep, 11/22/2010.

Character Names: Clint Miller’s middle name is Robert. Submitted by gracep, 12/1/2010.

Location: Durrant Art Gallery building was at 23732 Malibu Road near the intersection of Webb Way and PCH, which was down the hill just a couple of hundred yards from where Raymond Burr lived at the time. Its currently Pritchett Rapf Reality. Posted by Eric Cooper, 10 April 2010.

When Hutchings slams the door at the end of the scene where Paul and David interview him outside his apartment, the entire wall behind him (look closely) vibrates. Shoddy construction I guess. Submitted by daveb, 4/14/2011.

Location: About 6 minutes in, there is an exterior shot of Malibu Road and then, as the guy enters, “24246” is visible on the gate where Jack Culross is painting. All this makes perfect sense. The house still exists and is just a few houses south of where Raymond Burr lived at the time making the shoot very easy for him to make his call time. Submitted by Eric Cooper, 23 May 2011. Some pictures here.
+ Since Raymond Burr didn't appear in that scene, he didn't have to be there at all. Submitted by Wiseguy70005, 2/23/15.

While Edna tells Perry her story, on the desk sit a cup and saucer from the Curious Coffee Set. Submitted by gracenote, 6/21/2011.

Once again, there is no Lt. Tragg even though Ray Collins receives credit for playing him. Submitted by gracenote, 6/21/2011.

CARS. (1) 1959 Buick Invicta Convertible, medium color w/similar color top, Lic No VBZ 553, Jack & Edna Culross. Seen several times, top up or down, with three different drivers. Invicta badge on fender forward of front wheel can be seen at 24:14. Invicta was the mid-range Buick series from 1959-63. It had a higher trim level and larger engine than LeSabre.

The two Sheriff's Deputies are wearing LA County shoulder badges but yet again have incorrect Cap Badges (#'s 2336 & 6358). They should be wearing the LA County badge that Gordon Jones wore in Ep#113. Another improperly dressed Deputy was in Ep#106. Added by Gary Woloski, 1/30/13.

Magic Hyphen: When Jack started to write his note there was a dash behind the name Edna. When he attached the note to the steering wheel it was gone. When the man (who folded the note) handed it to the police the mark was back. Submitted by H. Mason 11/13/14
+ Actually, three different notes were involved. The two with the hyphen are also different. In the first one, the horizontal lines of the 'E' are not parallel to the top of the page, the letters are taller and the hyphen is shorter and extends from the center of the 'A'; in the note the man hands to the police the letters are shorter, the hyphen is longer and extends from the bottom of the 'A.' Submitted by Wiseguy70005, 2/23/15.
+ More to the point, when he's writing the note, he holds the notepad in landscape orientation and writes in landscape orientation too. When he is clipping the note to the steering wheel, it's in portrait orientation as is the writing. Submitted by Clothears 05-Oct-2021.

Another inaccuracy from "two of [Perry Mason's] greatest fans" in the description of this episode. The book states that Edna "got wise" to the fake suicide from seeing the finished painting. Actually, she thought the painting was a fake, as she later tells Perry Mason in his office. [And don't say the book was written before the episode could have easily been viewed by the writers. VCRs were available (though expensive) during the time the book was written and "two of his greatest fans" certainly should have been familiar with an episode which had been in syndication for the previous 20 years.] Submitted by Wiseguy70005, 2/23/15.

Size Matters: When the search party of Perry, Paul and David are in the gallery parking lot (at about 23:45 on the DVD), Paul notes traces of a small caliber gun having been recently fired. But we've see the gun, at 21:00, and it's anything but small -- a Colt 1911 .45 automatic, if I'm not mistaken. JohnK, 13 October 2015
