Barney Rosenzweig (the show co-creator and producer) makes a cameo appearance (uncredited). He can be seen in the foreground as Cagney and Lacey walk down the stairs of the court house.
Petrie and Isbecki spend most of the episode trying to figure out what Coleman's first name is. It turns out to be Ronald, which means the desk sergeant has the same name as a Hollywood idol from the thirties, which he finds slightly embarrassing.
Goof: In the final scene the actor playing the corpse clearly blink his eyes.
Possibly because the story takes place over the weekend, the background score is classical chamber music.
It is mentioned that Christine Cagney is 38 years old.
Cagney mentions a niece in the baby clothes store. Up until a few episodes ago she hadn't had any contact with her only sibling for years. Something must have happened since the end of 'Matinee'.
In this episode we learn that Christine Cagney grew up in Westchester. She lived in a large mansion with her mother, grandmother and brother. Her mother died when Christine was 19 (and out of the country) and Christine hasn't talked to her brother since then.
The Lacey bedroom in the opening of the episode is shown backwards, typically in every other episode of the series, Mary Beth is shown on the right side of the bed, while in this episode she wakes on the left.
Mary Beth is on the phone with the Operator and states that she is Badge #340. In the opening credits, their shield numbers are #730 and #763 respectively.
