CARS: 1957* Ford Skyliner retractable, black, top up (Mason) *stock footage from prior season. From The Cars by Greg Cockerill.

Speaking of cars, when Perry pulls his Ford Skyliner into the studio gate, if you watch closely, you see that a VW Beetle passes by, a rare sight in 1959. Submitted by PaulDrake 33, 21 July 2008.
+ This happens a little past 21:30 into the episode. Submitted by Raja99, 5/7/2009.
+ There appears to be a large black cloth covering the signage on the building Perry stops at as he enters the studio (Fidelity Studio). I presume this building is supposed to be the security guard shack. However, as Perry proceeds, a sign that says Police Dept. can be seen above the door on the rear of the building. That makes me wonder what that black cloth is covering up. Submitted by Kilo 4/18/2018.

He enters the hotel bar and talks to a couple of friends, just after Perry, Della, and Paul come out into the lobby, and just prior to the first courtroom scene. Later, he is another spectator in court, as are “Miss Carmody”, Quiet Old Man #2, and Don Anderson. Submitted by alan_sings, 16 Oct 2010.
+ Not to be left out, Distinguished Gentleman #2 is sitting in an aisle seat, back row. Submitted by gracenote, 5/2/2011.
+Distinguished Lady #4 joins the courtroom scene on Perry's side. submitted by Bigbill767, 2/4/17.

Actor Jerome Cowan (Royce) once had the unenviable task of prosecuting Santa Claus. Submitted by MikeM, 11/01/2012.
+ Cowan also played the first murder victim in The Maltese Falcon. He was Miles Archer, the somewhat sleazy partner of Sam Spade (Humphrey Bogart). He was shot dead with "ten thousand insurance, no children, and a wife that didn't like him." Vladimir Estragon 022524.

Cold case / old case Perry also solved the murder of Rick Volponi - killed twelve years earlier. Submitted by H. Mason 9/28/14
Volpone was the name of a play by Ben Jonson, first produced in 1605-06 about a man who spreads a rumor that he's at death's door in order to test the reactions of his greedy acquaintances. The play was also the basis of a 1967 movie, "The Honey Pot" starring Rex Harrison, and that movie paid an homage to Perry Mason by having an episode of the show playing (in Italian) in the background of a scene, about which the Police Inspector comments, "A great genius. If it were not for Signor Perry Mason, every week, in America, an innocent person would be convicted of murder". Since the clip also shows Dee Hartford, it must be from TCOT Accosted Accountant, TCOT Missing Button, or TCOT Baffling Bug. jfh 12Jul2022

TCOT Loud Dress: One thing I love about the show is the production sound -- what you hear, absent the odd dubbed line, is the sound recorded on set. The crinoline Katharine Bard wears in the scene where she puts slippers on her husband makes quite the racket! OldDave 8/11/20
