After John Larroquette won the Emmy for Best Supporting Actor in a Comedy Series four years in a row, he asked that his name be taken out of consideration. He was also offered a spin-off series based around the character of Dan Fielding, but he turned it down.
According to Series Creator Reinhold Weege on the Season 1 DVD commentary, when it is mentioned in the first episode that Harry Stone is a Mel Tormé fan, friends and relatives of the famed jazz and pop singer called Tormé to tell him about the reference. Tormé was so flattered by the reference that when the series later contacted him about appearing on the show, he was more than happy to do so. Tormé has also stated that largely due to the "Night Court" references, he noticed that his audience at concerts started to get younger and younger and that his newfound resurgence was because of the show.
There's a scene where Dan Fielding (John Larroquette) is trapped in a motel room with a psychotic woman who acts out movie roles. While watching television, an announcer says, "We'll return to 'The Texas Chain Saw Massacre'", to which Larroquette says, "Seen that already." Larroquette was the voice of the Narrator in The Texas Chain Saw Massacre (1974) and the 2003 remake.
This show became part of NBC's semi-legendary "Must See Thursday", which opened with The Cosby Show (1984), followed by Family Ties (1982) (and later A Different World (1987)) then Cheers (1982), and then this show.
Harry was 34 when he was appointed to the bench. He was appointed because he was the only candidate on the list to have answered the phone on the Mayor's last Sunday in office. He was the last name on the list. As he says, he got to be a judge "because I was home."
After Selma Diamond passed away following the completion of Seson 2, she was replaced by Florence Halop, due largely to the fact that she had comedy timing and mannerisms similar to Selma. However, when Florence passed away after completing just one season (Season 3), it was decided by the producers to hire a younger actress for the role, and Marsha Warfield was hired as Roz.
According to series creator Reinhold Weege on the Season 1 DVD commentary, many of the hookers and pimps are named after his friends. He comments that the references are his way of saying "hello" to these people.
Near the beginning of Season 7, Markie Post found that she was pregnant. The writers quickly came up with a story arc that included Christine's romance and marriage to Detective Tony Giuliano (Ray Abruzzo) and her following pregnancy. That way they did not have to try to hide it.
According to Reinhold Weege on the Season 1 DVD commentary, Harry Stone's appointment to the bench is loosely based on a real-life incident in Los Angeles. According to Weege, the Mayor, in an effort to hurt his replacement (a bitter political rival), filled the last remaining judicial posts with under-qualified candidates. Harry Stone was appointed to the bench, despite having barely enough experience practicing law.
The series was notorious for "recycling" actors and actresses in different roles. For example, Jack Riley appeared as Emil Dutton, Warren Wilson, Dr. Flick, Beepo the Clown, Mr. FrouFrou, and Jim Wimberly. Judy Landers appeared as an unnamed girl (Dan's date), Maj. Roberta Savage, and Vickie Guyer.
Bull was originally written as a towering intimidating hulk with a superior intellect. As the character developed, however, he grew into a dim but cuddly soul, whose intellect was limited to useless trivia.
Season eight was to be the last. Harry and Christine were to marry, Dan becoming a priest, among other big cast shake-ups. At the last minute, NBC renewed the show for one more season, and the Harry and Christine romance never came to fruition, with Dan going after Christine in the series finale instead.
John Larroquette was approached during Season 6 about starring in Madhouse (1990). However, executive producer Reinhold Weege would not allow him the time off to make the film. Because of delays in the film, Larroquette was approached again during Season 7. This time Weege and the film's producers worked out a schedule that would allow Larroquette to work on both projects simultaneously. Mondays to Thursdays Larroquette would rehearse for the series during the day and work on the film all night. On Friday nights the series would tape its episodes. As soon as taping finished, he would go to the film's set and work all weekend.
The series was originally set to debut at the start of the 1983-84 season. NBC, concerned about Harry Anderson's lack of acting experience, decided to delay the show. NBC ended up cancelling every new series that premiered that September, and the show was picked up as a mid-season replacement.
It is mentioned several times that Dan's real first name is "Reinhold", a name everyone else finds very unappealing. This is a reference to series creator Reinhold Weege. A possible continuity issue arose with the character of Dan's mother, who always referred to her son as "Danny". Whether this meant Dan actually was his name, or that she was simply calling him by his preferred name, was unclear.
The deaths of Selma Diamond and Florence Halop resulted in beliefs and urban legends about a curse on the parts. Some have even believed this was a reason as to why the much younger Marsha Warfield was cast as Roz.
