* ActorSharedBackground: Matt Devlin is of Irish ancestry, just like JamieBamber.
* {{Corpsing}}: In-and-out of universe. Matt struggles not to laugh at a witness' idiotic comment and eventually does lose it, even turning away from the camera to compose himself, indicating that it's Creator/JamieBamber himself cracking up, especially since the straight-faced Ronnie continues questioning the witness as if nothing has happened. Ironic, as it's Bradley Walsh who has the comedic background.
* DeletedScene: There are slight differences in what's aired on Creator/{{TheBBC}} and what's aired on [=BBC=] America because of this. Full episodes can be found on the internet or the [=DVDs=].
* DyeingForYourArt: Walsh, to simulate Brooks' [[AddictionDisplacement sugar craving acquired after he gave up alcohol]], gained two stone in weight.
* FakeIrish: Subverted. Creator/JamieBamber was born in London, but has Irish ancestry and citizenship thanks to his mother. Matt reveals his Irish heritage to a young prostitute he's interrogating and states that during his rookie year's he was "called mick for the first 6 months because my family are Irish", but his background might be slightly different--in an interview, Bamber described Matt as being from "an immigrant Irish family" indicating that he was born in Ireland and then emigrated to England.
* HilariousOuttakes: The special features of the Season 2 DVD include an 8-minute gag reel.
* IronyAsSheIsCast: Matt butchering the French language when trying to talk to a witness when in RealLife, Creator/JamieBamber speaks excellent French (aside from an early childhood spent in Paris, it's one of two languages, the other being Italian, that he studied for his Modern Language degree).
* KeepCirculatingTheTapes: Only Season 1 (Series 1 & 2) and Season 2 (Series 3 & 4) have been released on DVD in the US. To watch the remaining episodes, which have been released in the UK, anyone in Region 1 will need to either (a) purchase a universal DVD player, or (b) scour the internet. Luckily, Series 5-8 are readily available, which is very good as season 8 was never even aired on BBC America.
* McLeaned: [[spoiler:Matt Devlin]] was killed in a drive-by shooting when actor [[spoiler:JamieBamber]] finished his contract; at the time he was doing a pilot for a US show which was not ordered to series. The writers probably wanted to kill off a major character to provide good drama, so it's a pretty classic example of Reason #1 for this trope the following episode was one of the series best as the team struggled to deal with their grief while doing their best to ensure that his killer was brought to justice.
* PlayingAgainstType: Walsh is a well-known ''comedic'' actor and game show host who was thoroughly impressive as Brooks.
* RecursiveImport: Has begun airing on BBC America.
* ShortRunInPeru: Episodes 8 to 13 of Season 1 had already aired in Canada.
* ThemeMusicAbandonment: Though it must be said, this show ''does'' have [[http://www.youtube.com/watch?v=WPPmP4YnVdE a fairly rousing theme of its very own]].
* TooSoon: Because its plot bore considerable similarities to a RealLife murder that occurred the day before it was scheduled to air, the Series 8 finale "Repeat To Fade" was pulled from the schedule and replaced with a Season 5 repeat. It took nearly a month for it to be rescheduled.
* TheWikiRule: [[http://lawandorder.wikia.com/wiki/Law_%26_Order_Wiki Law and Order Wiki.]]
* YouMightRememberMeFrom: Creator/JamieBamber (DS Matt Devlin) spent four years as heroic pilot Lee Adama on ''Series/BattlestarGalacticaReimagined''. [[note]] And thanks to his near-perfect FakeAmerican accent on the previous show, some viewers of ''LOUK'' thought that he was faking the ''[[YourCostumeNeedsWork British]]'' one. [[/note]]
