* ActorAllusion: Malcolm's office is referred to as "The Lair of the White Worm" in Series 1. Creator/BramStoker's lesser known horror novel, ''Literature/TheLairOfTheWhiteWorm'', received [[Film/TheLairOfTheWhiteWorm a loose modern-day adaptation in 1988]] and starred--yep, you guessed it --Peter Capaldi.
** Terri is referred to as "Nurse Ratched" by Fergus and Adam at one point. Joanna Scanlan played a Nurse Ratched {{Expy}} in an episode of ''{{Series/Spaced}}'' which contained a WholePlotReference to ''OneFlewOverTheCuckoosNest''.
** Obviously not deliberate, but since Peter Capaldi was cast as the [[Series/DoctorWho Twelfth Doctor]], it's become extremely retroactively funny how often Malcolm's rants involve time travel and other science fiction tropes.
*** Even more coincidentally, in one of the DVD commentaries, the cast jokes about Capaldi someday being cast as the next Doctor.
* EnforcedMethodActing: For the enquiry episode, the cast were given no rehearsal or preparation before filming. Furthermore, there were no opportunities for the actors to talk to one another between re-shoots, and were kept separate from the "witnesses", like an actual enquiry.
* ForeignRemake: In 2006, ABC ordered a pilot for an American version of ''The Thick of It'' starring Oliver Platt. By most accounts it was terrible and consequently was never picked up. ''Series/{{Veep}}'' fared much better, though it's more of a SpiritualSuccessor than direct remake.
* HeyItsThatGuy: ''The Thick of It'' has a surprisingly high "It's that guy!" factor.
** As Malcolm Tucker was a rather late StarMakingRole for Creator/PeterCapaldi there are many examples. Malcolm caused this for people who saw Peter Capaldi in ''Series/TorchwoodChildrenOfEarth'' as the much more sympathetic civil servant John Frobisher, the still sweary but more tragic Mark Jenkins in ''{{Skins}}'', or way earlier than that as the Angel Islington in ''{{Neverwhere}}'', or ''still'' earlier as the {{Adorkable}} Danny Oldsen in ''Film/LocalHero''. And this all ultimately leads up to the fact that he is now [[Series/DoctorWho the Twelfth Doctor.]]
** Cal "The Fucker" Richards is ''[[Franchise/PiratesOfTheCaribbean Cutler Goddamned Beckett]]'', as if he needed to be even ''less'' likeable.
** Peter Mannion is played by [[Series/AshesToAshes Supermac]], perhaps better known as [[Film/VForVendetta Lewis Prothero]] or, going further back, as the original [[Theatre/LesMiserables Inspector Javert]].
** Seeing [[Series/MyParentsAreAliens Brian Johnson]] walk in and use the word "pisser" is likely to shock those familiar with his earlier work.
** [[Series/GameOfThrones Edmure Tully]] is on the Golding Inquiry, slightly more competent than usual.
* LifeImitatesArt: [[http://www.guardian.co.uk/tv-and-radio/tvandradioblog/2010/apr/29/gordon-brown-bigotgate-thick-of-it Scarily often in UK politics]].
* PeripheryDemographic: Thanks to the HeyItsThatGuy effect. Peter Capaldi plays the Doctor on TV in ''Series/DoctorWho'', and Alex Macqueen plays the Master on audio in AudioPlay/BigFinishDoctorWho. Since Doctor/Master is the most popular ''Doctor Who'' slash pairing, ''a lot'' of ''Series/DoctorWho'' slash fans have turned to ''The Thick of It'' to see both men getting all up in each other's faces.
* RoleEndingMisdemeanor: In 2005 Chris Langham was charged with downloading child pornography. Rather than make a full second series without him, the producers made two hour-long specials for which they [[PutOnABus put him on a bus]], leaving the door open for him to return if he was found not guilty. He was found guilty at his 2007 trial and served 15 weeks in prison, and his character Hugh Abbott disappeared from the show never to return.
