History Trivia / LawAndOrderCriminalIntent

* LikeBrotherAndSister: While the relationship between their ''characters'' is ambiguous to say the least, D'Onofrio has stated on several occasions that this is the real-life relationship he shares with Kathryn Erbe -- something which is fairly well evident whenever they do joint interviews.

* OldShame: Creator/ChrisNoth considers his time on the show to be this, not because of the show itself, but rather his poor working relationship with Creator/DickWolf. The men have had bad blood since the controversial removal of actors Dann Florek and Richard Brooks, as well as the firing of Michael Moriarty from ''Series/LawAndOrder'' back in TheNineties. Eventually, this led to his own firing from said show after he openly complained about Wolf, which resulted in his character written off as [[PutOnABusToHell being transferred]] [[ReassignedToAntarctica to Long Island for ten years.]]

* MissingEpisode: The episode "The Glory That Was..." has been taken out of rotation since after its first airing due to the ColdOpen having a scene with two women in bed together. The episode is not even on the season eight's [=DVD=]. Also, the episodes "Slither" from season five and "Beast" from season four have had certain lines ("He didn't have a pot to piss in" and "She was a restaurant hostess who put coke up her crotch!", respectively) either muted out or removed altogether when aired in syndication, although the line in the latter episode was eventually restored.

* ActorAllusion: A possible one, to Goren being [[Film/FullMetalJacket in the military.]]

* OldShame: Chris Noth considers his time on the show to be this, not because of the show itself, but rather his poor working relationship with Creator/DickWolf. The men have had bad blood since the controversial removal of actors Dann Florek and Richard Brooks, as well as the firing of Michael Moriarty from ''Series/LawAndOrder'' back in the 90s. Eventually, this led to his own firing from said show after he openly complained about Wolf, which resulted in his character written off as [[PutOnABusToHell being transferred]] [[ReassignedToAntarctica to Long Island for ten years.]]

* WrittenInInfirmity: For Nicholson's second pregnancy.

* ColbertBump: Goldblum shamelessly plugged the show on ''Series/TheColbertReport'', and Stephen Colbert himself guest starred in Season 3.
* CreatorBreakdown: Unlike other shows in the franchise, which are ensemble affairs, ''CI'' focused nearly-exclusively on Goren, and required Vincent D'Onofrio to have a punishing workload. D'Onofrio eventually had to be hospitalized for clinical exhaustion, so the producers brought in a second detective team and began the alternating format in consideration of their lead actor's health problems. Goren's weight gain throughout the later seasons of the show is also attributable to D'Onofrio's health issues.
* TheDanza: James "Jamey" Sheridan as Capt. James Deakins.
