When Quincy gets home, he removes his shoes. A minute later, the phone rings, and he rushes out the door, but he never puts his shoes back on.
In the scenes where the band is performing in the lounge, you can hear a (rhythm) guitar playing. However, if you look closely, both "guitarists" are actually playing bass guitars.
In watching this episode I figured out that it was most likely filmed in 2 separate hotels. One of those hotels is definately what is now the Hyatt Lake Tahoe Resort in Incline Village, NV. I could tell since I worked there back in 1988 and there were many scenes which kept me thinking this was filmed at the hotel prior to it becoming a Hyatt property. Prior to it being Hyatt it was the King's Inn. I also feel this was filmed at a Sheraton as well since there is one brief scene where paramedics are wheeling patients out of a guest room floor and into another room and you can see the Sheraton logo in reverse on one of the glass doors. Also, the Hyatt/King's Inn did not have a cabaret theater or a lower portion to the hotel. Since there are some scenes in a cabaret as well as people walking up from a downstairs scene I would assume that those were filmed at the Sheraton.
The proper term for a postmortem examination on an animal is "necropsy", yet Dr. Pines (with a medical degree from Harvard) and Dr. Quincy refer to the examination of Pines' dog Shaughnessy as an autopsy.
This episode marks the final appearance of Lee Potter, Quincy's first girlfriend in the show.
Quincy finds out that the murderer was able to convince the victim's father that his son was killed in Vietnam. The only problem, his son was killed in 1959, several years before the US got involved in Vietnam. [Editor's Note: According to the National Archives, the Vietnam Conflict for the U.S. began in 1956. The dates for the 'War' are given as between 1969 and the last U.S. troop withdrawal in April 1975. As the victim was described as enlisting in the Army (and not being drafted starting with the December 1969 draft lottery), he very well could have served and been killed in Vietnam at the time.]
The chalkboard in the classroom where Quince is teaching the pathology class at the university in Los Angeles (it has a list of words painted down the left hand side), can also been seen in the coroner's office in Lubbock, Texas later in the show.
When Quincy confronts the murderer in the hospital he tells the man that he has the bruise from the seat belt to prove he was driving. Quincy then pulls down the neck of the hospital gown to expose the man's right shoulder. Since he was driving, the bruise should be on the left shoulder.
The only episode in the whole show, in which Quincy does not appear.
Interestingly, there is no autopsy performed in this episode.
Goof: As race car driver Mark Hellman readies for his qualifying round (after promising Quincy to tell him all he knows afterwards), a close up shows him wearing a pair of white socks and white KSwiss leather lace-up sneakers / trainers. After his crash, as he's put into the ambulance he's now wearing a pair of black shoes with red trim.
As is mentioned in the episode itself, the method by which Dr. Astin and the Lieutentant use to match the bullet to the murder weapon has been dismissed as being scientifically unsound because the chemical composition of its particles can be matched directly to the other bullets in the same series and thus cause confusion as to which weapon is the murder gun.
I learned this from the TRUTH IN JUSTICE website.
2nd visit to garage Quincy has tie no sweater, he then arrives at sisters house with no tie and sweater.
Outside garage, Quincy is leaning on the detective with his medical gloves on. Next scene he moves away but gloves have gone!
When Dorrie Larkin (played by actress Jane Greer) appears on the talk show near the end of the episode, the host introduces her with a clip of one of her movie appearances. However, the clip is actually of Jane Greer's 1959 guest appearance on the television series Bonanza.
In this episode it is stated, that Quincy worked as a surgeon in the past, before becoming a coroner. But in the episode "A Star is Dead" from season 1, he says that he had a private practice in the past (or at least he says that he doesn't have it anymore). These two facts doesn't really seem to match, although it is possible that both are true.
Until this episode, we knew almost nothing about Quincy's past life or at least his life before the show started. In this episode we learn some maybe surprising facts about Quincy's past life. We learn that he was married once to a woman called Helen, that she wanted kids while he didn't want some, at least not "now". Later we learn, that Helen got a brain tumor and died of it, and that Quincy blames himself for the death of his wife, because he didn't have enough time for her and didn't see the symptoms of the fatal illness. People who see this episode maybe will see Quincy in a different light now. You could say that this is the first episode in the show, where Quincy is portrayed as a "normal" person with personal issues, and not (or at least, not through the whole episode, because he also solves a crime in it) as the kind of superhero, as which you could see him in most of the episodes of the show.
This episode marks the first appearance of Anita Gillette in the show, who plays Quincy's first wife, Helen, in some flashbacks during the episode. Ironically Gillette reappears in season 8, now as a main character, playing Quincy's girlfriend and later in the season his second wife, Dr. Emily Hanover. Ironically you could say that Quincy married the same person two times.
Charles Percini and Bob Anderson are listed twice in the closing credits.
The paramedics who responded to the cardiac case were from Station 44, but stock footage of the exterior of Station 51 was taken from the series Emergency!. R.A. Cinader, the executive producer of this episode, also created Emergency!
