Mary Ann Mobley was Miss America 1959. Submitted by Jim Kramer, July 09, 2008.
+ Mary Ann Mobley appeared in both Perry Mason and The New Adventures of Perry Mason (Episode #5, “TCOT Telltale Trunk”). There were only 15 episodes of The New Perry Mason, so it was quite rare for a performer to appear in both. Submitted by PaulDrake 33, 4 October 2009.

Isabel Randolph makes her last of 3 appearances on Perry here playing Madam Rosa Bruening. Not only would it be her last appearance on Perry, it was her final screen credit in a busy 25 year career. Mrs. Randolph is known for playing snooty society matrons, and was quite famous in the 40's for playing Mrs. Uppington on the highly popular Fibber McGee and Molly radio show. Submitted by PaulDrake 33, 15 June 2013.

Location: About 27 minutes into the episode, Perry walks from his car into the Stanley Mosk Courthouse in downtown Los Angeles. This exact clip of him along side his car has been used in multiple episodes. There is also a clip in which he closes the car door. Submitted by Eric Cooper, 13 October 2010.
+ That the shot of him entering the courthouse is a stock clip is obvious: en route to the courtroom, Perry loses his pocket square, briefcase, and gets a haircut! DOD 4/10/18

Location #2: At about 4 minutes in, the night street scene location with the Chinese or Japanese neon signs and the Fuji film sign makes its third appearance (at least). It was first used in a story that featured Asian actors (sorry, i cannot recall the episode name); it also appeared within the last coupe of episodes. Submitted by catyron, August 16th, 2018

Uncredited Actors: Though it’s difficult to be positive, it looks like Don Anderson was one of the uniformed policemen sent with Lt. Drumm to Duke’s hideout. Anderson is one of the two left at the checkpoint on the road, and he has to do some fancy footwork to avoid being run down when Rudy (Anthony Eisley) drives on through. Anderson might also have been used in the seige scene closer to the cabin. Drumm repositions some of his men, addressing one of them as “Don,” but the actor has his back to us making identification impossible. Submitted by FredK, 1/27/2012.

The policeman shooting the tear gas was not a very good shot. [Item moved to "Spoiler Alert" section.] Submitted by Perry Baby 1/30/14

Perry runs in this one, even though it is the short distance between the police car he arrives in at the cabin to the main one where Steve Drumm is positioned. Submitted by mesave31, 03/18/15.
+ Perry also runs from the main police car to the foot of the hill. jfh 16Apr2018.

Although everyone pronounces Carmody as "Car-ma-dy" Perry pronounces it "Car-mo-dy." Submitted by Wiseguy70005, 3/20/18.
+ Just as he did when way back in Episode # 73, when first introducing our beloved courtroom spectator, waitress, and nurse, Miss Car-MOH-dee.

This is the final of five PM appearances for Rita Lynn, who developed the use of one-act plays as therapy for psychiatric patients...MikeM. 4/16/2018

West Bend Thermo-Servs: The West Band Thermo-serv carafe and at least one mug is on display in the viewing booth at the studio where the White Snow ads are being rehearsed and filmed. Submitted by catyron, August 16th, 2018

The Staircase Goes to Seattle: The well-used staircase set is now at Fern's house in Seattle. Submitted by catyron, August 16th, 2018
Staircase in Seattle Hmmm, must be a movie there. Errm ... Submitted by Clothears 11th Ost 2020.

The Return of the Upside-Down Law Book: After a couple of seasons with no upside down law books, we see one in Perry's office in the closing scene. It is on the right side of the screen, near the giant urn-thing. Submitted by catyron, August 16th, 2018
+ Interesting that the book is aright on the shelf halfway through the episode. jfh 21Aug2018.

This is the 7th and last PM appearance for Don Dubbins, the last three of which were as Deputy D.A. Bill Vincent. Submitted by JazzBaby, 6/28/2019.
