In early 1991, a Season 5 episode had two female characters, Abby, played by Michele Greene and the newcomer C.J., played by Amanda Donohoe kissing each other. The scene was recognized as the first kiss between two women in a prime time American series and was considered quite controversial.
William M. Finkelstein became executive producer of "L.A. Law" shortly after his series Civil Wars (1991) was canceled. Finkelstein transferred two "Civil Wars" characters from their New York law firm to "L.A. Law": attorney "Eli Levinson" (Alan Rosenberg) and his secretary, "Denise Ianello" (Debi Mazar).
Series creator Steven Bochco was so taken with the show being parodied on the cover of the October 1987 issue of Mad Magazine that he staged a photo shoot with the show's actors in the exact same positions that their caricatures had appeared on the magazine's cover.

Series co-creator Terry Louise Fisher, former deputy district attorney for Los Angeles County, former entertainment lawyer for 20th Century Fox, and producer-writer for Cagney & Lacey (1981), composed a form letter she was thinking of sending to lawyers who complained about the show: "Dear So-and-so: If I were a good lawyer, I'd still be practicing law. Instead, I'm stuck in Hollywood, making 10 times as much money. I hope you are as conscientious about your clients as you are about our show. Thank for your writing."
The license plate in the beginning of the opening credits was during the first seven seasons mounted on the rear of a Jaguar, but for the final season it changed to being mounted on a Bentley Continental R - a car which was mentioned in several episodes of the eighth season when Arnie Becker was thinking of buying one. He finally received one as a gift in episode 3 of the same season.
The series ended their last day of shooting their final episode the morning of May 10, 1994. Actor Corbin Bernsen called into the Howard Stern Show about a half hour before they wrapped for the last time.
