* CastTheExpert: Robert Mandan had lots of actual SoapOpera experience on shows like ''Series/SearchForTomorrow'' and ''The Doctors'' in the years before he was cast as Chester Tate.
* CowboyBebopAtHisComputer:
** Before the show had even aired, ''Newsweek'' reported that ''Soap'' was a sex farce which contained a scene of a priest being seduced inside a confessional. While the "sex farce" descriptor wasn't ''entirely'' off base, that specific scene never happened.[[note]]The closest thing to something like that happening was when Corrine reveals her identity to her ex-boyfriend, Father Flotsky, in a confessional, and then tries to woo him ''outside'' the confessional, with nothing physical happening whatsoever.[[/note]] A boycott of the show by religious groups ensued, advertisers and affiliates got nervous, and some of the show's producers believe the show never fully recovered.
** Gordon Jump (Chief of Police Tinkler) originally refused to take the part because he'd heard the rumors that the show was lewd and immoral, only to realize he was wrong when the producers actually showed him some episodes.
* TheDanza: Creator/IngaSwenson as Ingrid Svenson.
* ExecutiveMeddling: A rather strange example that was ultimately averted involved ABC requesting the Campbells' last name be changed to avoid confusion with the similarly-named soup company.
* FollowTheLeader:
** ''Soap'' was a clear influence on ''Series/ArrestedDevelopment''.
** ''Soap'' itself was the primetime answer to the previous season's hit ''Series/MaryHartmanMaryHartman'', a daytime soap opera parody from Harris's former boss Creator/NormanLear.
* FriendshipOnTheSet: Creator/KatherineHelmond was well-liked on the set and became friends with virtually everyone in the cast, particularly Creator/RichardMulligan and Creator/RobertGuillaume.
* HostilityOnTheSet: A subversion occurred with Cathryn Damon. Since she lived on the other side of the country from where filming occurred, the stress of flying back and forth between both places left her drained and withdrawn to the point where she couldn't bond with the majority of the cast (save for her onscreen husband, Richard Mulligan).
* MarathonRunning: Beginning at Midnight, 1/1/93 Creator/ComedyCentral kicked off a run of the show with the marathon ''All the Soap in the World'' which aired every episode in order non-stop over a three day period. When it then entered the regular line-up, episodes aired at 7:30 Mon-Sat, with a mini-marathon of all 6 episodes repeating Sunday afternoons under the title ''Soap Block''.
* RealLifeWritesThePlot: Not exactly, but a perceived coincidence. Catherine Damon passed away in 1987 from cancer, and a year later, her on-screen husband Richard Mulligan starred in a new series, also created by Susan Harris, [[Series/EmptyNest about a man who's wife died recently.]]
* ScrewedByTheNetwork: According to co-producer Tony Thomas, the reason why the show was abruptly cancelled at the end of season four was because ABC was sick and tired of the angry letters from MoralGuardians over the content of the show.
* WhatCouldHaveBeen:
** Originally, Chuck was to be a ''much'' darker character and would have been revealed to be [[spoiler:the actual murderer of his brother Peter Campbell, due to jealousy]]. This storyline was scrapped when Chuck (and Bob) proved to be popular with viewers, resulting in [[spoiler:Chester being revealed as the murderer]].
** Susan Harris had created a five-season story arc for the show prior to it even airing. The show was canceled after four seasons, leaving the fates of several main characters undetermined and many plot threads never to be resolved.
** Father Timothy Flotsky was originally intended to be a less traditional priest; one planned joke involved replacing the traditional communion wafers with Oreos. [[ExecutiveMeddling ABC was not amused.]]
** According to Rod Roddy's fellow game show announcer Randy West, the producers' first choice for the announcing gig was Creator/CaseyKasem. Kasem, however, felt that the material was too controversial; he only announced the very first episode before Roddy replaced him.
** In an interview Jay Johnson once discussed the scene in which Jodie stashes Bob in the refrigerator, saying he and Billy Crystal had collaborated heavily on the concept and gags in the scene. Afterward Billy Crystal wanted a writing credit, but was denied. After that, Crystal was far less motivated to collaborate.
* YouLookFamiliar: Inga Swenson and Caroline [=McWilliams=] would return as different characters for the show's SpinOff ''Series/{{Benson}}''.
