The shot of the police arriving in the cul-de-sac appears to be a clip from five or more years before the rest of this episode was filmed, as none of the cars look newer than early 1950s. Submitted by Tony, 4/5/2019.

Sightings: At least one of the individuals in the lineup with looks like one of the courtroom spectators (behind Burger and Tragg) in the “Style P” opening credits used in episodes 40-69. Perhaps he was a crew member or a regular extra. Submitted by Alex Blackwell, 4/25/08. Posted by daveb.
+ He turns up again in the courtroom gallery, behind Burger. Submitted by gracep, 10/3/2010.
++ Now that he is included among our favorite frequent faces as Distinguished Gentleman #2, read more about him and other regulars here. See also additional sightings below. Submitted by gracep, 11/5/2010.
+++ Distinguished Lady #4 and Little Old Lady #2 join the courtroom scene on Perry's side. Submitted by BigBill767, 12/9/16.

Patrica Taylor, a.k.a. “The Terrified Typist,” is played by Joanna Moore, wife of Ryan O’Neal and mother of Tatum O’Neal. Posted by PaulDrake33.

Hank Patterson, who 7 years later would appear as Mr. Ziffel on "Green Acres", makes a short appearance as Jack Gilly, the man in the boat. Patterson had 190 film credits, a huge amount considering I don't remember anything but "Green Acres"! submitted by 7539 May 2017
+ I was kind of hoping Arnold would confess from the gallery in the last scene. OldDave, submitted 7/8/2020

One of the few episodes where Perry’s client actually takes the witness stand. As you may know, the District Attorney is prohibited from calling the defendant to testify, so in order to testify, the defendant must be called by his own attorney. In this episode, Perry does not reveal the name of the murderer until Burger has rested his case and Perry has began to present his side of the case. Submitted by PaulDrake 33, 6/18/2009.

Goof: After questioning a prosecution witness, Burger turns to Perry and says "Your re-direct." Re-direct is something the prosecutor does. Perry would cross examine. Submitted by Ben B, posted by daveb, 12/18/10.
+ Jefferson/Kincaid was called as a witness by Mason, so his first examination is the direct, Burger's is the cross-examination, and any further questions by Mason are re-direct. I believe that Burger's remark is correct. Submitted by FredK 12 July 2012.
++ Burger says it after his cross-examination of Patricia Taylor not Duane Jefferson. Submitted by Wiseguy70005, 2/15/14.
+++ Wiseguy is correct, Mrs. Taylor was the witness following Kincaid on the stand. But since she was also Mason's witness, Burger is still correct. Submitted by FredK 28 April 2014.

Sightings: You can see the man first spotted by PaulDrake33 in #48, TCOT Purple Woman, in this episode—a dark-complected man with a pencil-thin mustache who resembles Leo Carrillo. There is a really close shot of this Pencil Mustache Man in a cut to Patricia Taylor sitting in the courtroom gallery. “Miss Carmody” sits in the back row during the hearing for a motion for a new trial. Submitted by gracep, 10/3/2010.
+ She certainly looks similar, but I believe this is a different lady. alan_sings, 16 Oct 2010.
++ I agree with alan_sings. This was not Miss Carmody. Freeze frame plus zooming in showed her to be very similar, however. Submitted by Clothears, 17-Jan-2021.

Location: Just short of 10 minutes in we see an exterior shot of Parker Center at night. There are many daytime shots but this is the only nighttime one I've seen. Submitted by Eric Cooper, 13 January 2011.

Location: Almost 15 minutes into the episode Paul and Perry drive to Senator Taylor's estate which in reality is what is known as Greenacres. It is the lavish estate comedian Harold Lloyd built. It was known for its 15 acres of amazing gardens. It remained intact until 1975. It remains on 5 or so acres and is owned by supermarket magnate Ron Burkle. Submitted by Eric Cooper, 13 January 2011.

Another TV lawyer appeared 3 years later with the name George Baxter on the series Hazel played by Don DeFore. In the Terrified Typist novel the character's name is "Munroe Baxter." Submitted by Wiseguy70005, 2/15/14.
+ Munroe Baxter becomes George Baxter. The Pitkin Principle (See Episode 18) at work again. Submitted by BobH, 12 April 2016.
++ And the actress who played George Baxter's wife on Hazel appeared in the episode previous to this one. Submitted by 65tosspowertrap, 4-28-2014.

Scenes of screen tests of Raymond Burr (and William Hopper!) as Perry Mason from the novel The Case of the Terrified Typist are included in the Perry Mason 50th Anniversary Edition DVD set. These scenes, however, are with a character (Yvonne Manco) that wasn't written into the TV version so one can't compare the two screen tests with the final version. Submitted by Wiseguy70005, 2/15/14.

Brent Building: In this story we learn of two more businesses in the Brent Building: South African Diamond Co and Crawford Jewelry.

More Brent Building tenants are revealed in episodes 68, 97, 149, 238 and 264. Submitted by H. Mason 10/10/14
