* ActorAllusion: A possible one, to Goren being [[Film/FullMetalJacket in the military.]]
* ChannelHop: From [=NBC=] to [=USA=] with Season Seven.
* 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.
* HarpoDoesSomethingFunny: In the special features of the Season 1 DVD, the producers say that after hiring Vincent D'Onofrio they basically allowed him to do whatever he wanted, leading to many FunnyMoments and one of the most distinctive characters in the crime genre.
* 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, 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.]]
* WhatCouldHaveBeen:
** Imagine if Goldblum had decided to film a few more episodes for the series ender. Nichols and Goren cracking a case together would've just been awesome.
** Apparently, there were plans to write an episode that revealed that Nicole Wallace [[spoiler: wasn't dead]], but said plans never came around to making it into an actual episode.
** There were plans for L&O, SVU, and CI to have a major crossover with Goren being the central character investigating a potential terrorist plot. Then 9/11 happened and the plans were abandoned and never revisited while the Mothership and CI were still on the air.

* WrittenInInfirmity: For Nicholson's second pregnancy.
