Locations: This episode opens with Perry and Della taking Angels Flight the Funicular railroad (more information here) in downtown Los Angeles. About halfway through this episode Perry and Steve go to Los Angeles County Hospital (some pictures here) and then a few minutes later Paul Drake gives chase through historic Olvera Street, one of the oldest areas of downtown. A tourist stop, Olvera Street is still there and looks basically the same. Posted by Eric Cooper, 25 September 2009.
+ It was a real treat to see the Angel's Flight railroad in action ... but the use of Olvera Street as a location simply confused me. I recognized it as once, and figured Paul was running around in Los Angeles, so i was very slow on the uptake when Paul began talking about the young man being a U.S. citizen -- it was well into the dialogue between Paul and Donna Reales before i realized that the entire Olvera Street scene was supposed to be taking place in Mexico!

This episode is the *only* episode of Perry Mason filmed in color. This "experimental" color episode is episode #262. Coincidentally, in Nazi Germany, their first experimental jet fighter (built my Messerschmitt) was the ME-262. Submitted by Charles Richmond, 9/14/2013.
+ "How Hitler Lost The War" is a great documentary that looks at Nazi "Wonder Weapons" like the 262 & the V1/V2 Rockets that led to the US Space Program & Perry Space-oriented episodes. Mike Bedard 3.8.15.

That's a good way to remember "262" and it was missing on MeTV's lineup. Found a nearly complete YouTube version: This was uploaded last month (12/2016) and although I watched it on a UHD TV it seemed formatted for a SmartPhone in ‘Portrait’ mode. It’s missing first and last few seconds, credits and edges of the picture and the audio has a "Donald Duck" quality. Submitted by pilotart 01/21/2017.

Curious Coffee: Ben Huggins serves coffee to Donna Reales using cups from the Curious Coffee Set. More info here. Submitted by daveb, 12/30/2010.
+ As in episode 243, The Case Of The Fatal Fortune, there appears to be a graphic design of some sort inside the rim of the cup. jfh 18May2018.
+ + I see no graphic design inside the curious coffee cups (served by a silver-plate carafe with matching creamer and sugar) -- they look like the same cups to me that they have always been for almost 200 episodes. What appears black in the b&w episodes is a very dark green. Also, the transferware cups seen frequently at Clay's Grill, with the image of a cabin-style building on them, are red-on-white, and the cup interiors are also covered with a transferware pattern.

+ Distinguished Gentleman #1 plays a yellow-clad waiter at Clay’s Grill in at least two scenes. “Miss Carmody” turns up among the courtroom spectators. More about these folks on the “Who Is That?” page. Submitted by gracenote, 6/5/2011.
+ + The Pencil Mustache Man also appears at the crime seen of Lennie's dead girlfriend. He's standing in the back wearing what look's like a cabbie's hat. Submitted by Kenmore, 10/3/2011

Harry Holcombe Judged 3 Perrys & appeared in 2 others as Mr. Big & a Senator [IMDb]. Mike Bedard 3.5.15.

Viewers will remember Victor Buono as King Tut in the Batman series of the mid sixties. Seems like he acts and dresses like he was previewing his character in that series here in this episode. Submitted by HamBurger, 07/02/2017
