* ActorAllusion:
** When Michael thinks Dwight has betrayed him to Charles (Idris Elba), he checks him for [[TheWire a wire]] in the parking lot.
** Creed gets several of these.
*** In "Money" Creed reveals that whenever he gets into debt he dumps it all on his alter ego, "William Charles Schneider": Creed Bratton's real life birth name.
*** Furthermore, in "A Benihana Christmas", Creed can be seen singing "Spinnin' and Reelin'", a song by Creed Bratton.
*** In a deleted scene from "Booze Cruise", Creed talks about being the lead guitarist of the 1960's folk group the Grass Roots (best known for their hit "Let's Live for Today"), which Creed Bratton actually was. The finale outright confirms this connection.
** In the season 6 Christmas episode, Michael is annoyed that Phyllis is the Santa, so he dresses up as Jesus. [[BruceAlmighty This is not Steve Carell's]] [[EvanAlmighty first encounter with the Lord.]]
** In "Cafe Disco", Michael lip-syncs to "Gonna Make You Sweat (Everybody Dance Now)", just like Steve Carrell did during the end credits of ''EvanAlmighty''.
* CastTheExpert: Andy Buckley, who plays former-CFO David Wallace, is a RealLife stock-broker.
* TheDanza: Phyllis, Angela, Oscar and Clark. Creed may be a Danza, but lives in AsHimself and AdamWesting territory.
* {{Defictionalization}}: Famous props in the show like Dwight's bobble-head of himself and Michael's "World's best boss" coffee mug have been made into merchandise that fans can buy.
** Not only is there Dwight's bobble-head, there are bobble-heads of the whole main cast available.
** In "Business Ethics" Michael mentions viewing a YouTube video called "[[SesameStreet Cookie Monster]] sings [[TayZonday Chocolate Rain]]". You'd think a video like that would have already existed on [=YouTube=] but it didn't. [[http://www.youtube.com/watch?v=zJsJ5dW7jHo A video]] was created by a fan after the episode aired.
** Staples now sells real Dunder Mifflin paper.
* DeletedScene / DVDBonusContent: A crapload of canonical, extra features, and webisodes can be found online at NBC's [[http://www.nbc.com/The_Office/video/categories/deleted-scenes/28287/ Office website]].
* DirectedByCastMember:
** Paul Lieberstein, 7 episodes ("Money", "Two Weeks", "Gossip", "Whistleblower", "Sex Ed", "Training Day", "The Incentive")
** B.J. Novak, 5 episodes ("Scott's Tots", "The Seminar", "The List", "Trivia", "Free Family Portrait Studio")
** Steve Carell, 3 episodes ("Broke", "Secretary's Day", "Garage Sale")
** John Krasinski, 3 episodes ("Sabre", "Lotto", "The Boat")
** RainnWilson, 3 episodes ("The Cover Up", "Classy Christmas", "Get the Girl")
** Mindy Kaling, 2 episodes ("Body Language", "Michael's Last Dundies")
** Ed Helms, 2 episodes ("Christmas Wishes", "Welcome Party")
** Brian Baumgartner, 1 episode ("After Hours")
** Lieberstein has also been the showrunner since season 5, and many additional episodes have been {{written by cast member}}s.
* EditedForSyndication: In the TBS version of "Performance Review" Dwight wonders if the suggestion "Dont Sleep with your Boss" refers to "You boning Jan". In the syndicated version he says "You doing Jan".
** Also, in "Sexual Harassment" Michael says "The only thing I am worried about is getting a boner", in the syndicated version he said "The only thing I am worried about is getting a shwing"
** Episode 'Koi Pond' had its cold opening removed which involved a fake hanging by Michael and was also omitted from DVD release. Fortunately, the clip can still be seen on the official site.
* EnforcedMethodActing: Season's 2 "The Carpet" is centered around an incredibly foul smelling... "thing"... left behind in Michael's office. Unbeknownst to the rest of the crew, Steve Carell had thrown a stink bomb into his office just before shooting began on the scene in which the employees smell the odor in his office. Unless they postponed filming, there's a good chance that everyone's reactions to the smell, especially Kevin's, as Michael locks him in his office for a short while, is not acted.
** Another moment, also courtesy of Steve Carell, is his incredibly awkward kiss with Oscar in "Gay Witch Hunt". He was only supposed to kiss Oscar on the cheek, but in that one take, Carell just wouldn't let go of Oscar Nunez (who plays [[TheDanza Oscar]]) and kept coming closer and closer. Oscar trying to pull away was completely real. In fact, they had luck the camera kept fixed on Michael and Oscar (and that Nunez managed to keep a straight face), because the rest of the cast were all cracking up.
* ExecutiveMeddling: The reason why the pilot episode is an Americanized version of the British pilot episode.
** Going into the 8th season, there was some meddling with [[spoiler:Michael/Deangelo's replacement. NBC apparently wanted Catherine Tate to replace them, and James Spader to replace Jo Bennet, with more frequent appearances. Only the second one went through.]]
* FakeAmerican: Idris Elba (Charles) is actually British. The character seems vaguely transatlantic, especially in terms of accent, and anyone who's seen ''TheWire'' knows Elba could have done a much more convincing American accent if he'd wanted to. Charles is also an avid soccer fan.
* HeyItsThatGuy:
** [[TheHangover Mr. Leslie Chow]]/[[Series/{{Community}} Seņor Chang]] is a member of Michael's improv class.
*** As is [[Series/TheDailyShow Wyatt Cenac]]
** [[{{Glee}} Artie]] was a pizza delivery boy kidnapped by Michael.
** [[Series/{{Community}} Shirley]] worked briefly with Dwight in Staples.
** [[TheWire Stringer Bell and Beady Russell]] got a job as Michael's boss in Dunder-Mifflin and Human Resources rep, respectively. [[TheWire Frank Sobotka]] also worked at the Syracuse branch of Dunder Mifflin
** [[http://www.youtube.com/watch?v=0hm7pp_JFOs Blow job girl]] is the new receptionist.
** [[InTheLoop That snotty American intern]] who looks like a stick-insect is the new Jan.
** [[MadMen Harry Crane]] tried to get Pam to continue her college degree.
** Why is [[{{Series.Heroes}} HRG]] flirting with Angela?!
*** Mohinder is dating Kelly now? [[spoiler: She and Ryan run away together, leaving Ryan's son with him.]]
** [[Series/ParksAndRecreation Ann]] is Karen (though she was on this first, and was offered to star in what was originally conceived as its spin-off because of her performance as Jim's final girl before true love).
** Jan is [[Series/{{Monk}} Trudy]]!
** Nellie may or may not have previously been [[Series/DoctorWho a temp]].
** Looks like [[Series/ArrestedDevelopment Gob]] decided to give up on the Bluth Company and try to go for Dunder Mifflin.
** [[Film.ScottPilgrim Comeau]] worked for Sabre!
** [[Series/AmericanHorrorStoryMurderHouse Tate]] is Michael's nephew and get's spanked by him too
** Before [[Series/BreakingBad Gale Boetticher]] helped Walter White cook meth, he was a "glorified fact checker" for Sabre.
*** [[Series/BreakingBad Badger]] is one of Dwight's cousins.
** Michael dated [[Series/CarolineInTheCity Annie]]!
** [[Film/{{Stargate}} Dr. Jackson]] returned from Abydos!
** Pam's father is [[CHiPs Sgt. Getraer.]]
* HeyItsThatVoice: Dwight's new best friend Rolf in Season 5's finale is [[WesternAnimation/TheVentureBrothers freakin' Rusty Venture]].
** [[AnchormanTheLegendofRonBurgundy Champ Kind]]'s first appearance as Todd Packer was over the phone.
* LifeImitatesArt: In a ninth season article, Nellie tricked Andy into believing that he's related to Michelle Obama. Turns out that Ed Helms [[http://www.geni.com/blog/look-whos-related-ed-helms-and-michelle-obama-377614.html really is related to Michelle Obama]], as well as Mitt Romney, John [=McCain=] and Creator/AmyPoehler (of Series/ParksAndRecreation).
* MarathonRunning: When cable channel TBS secured the rerun rights to the show, they made a habit of airing four or six episodes in a row one day a week, instead of one episode a day. This lead to a lampshading on an episode of ''WesternAnimation/{{Futurama}}''... the Planet Express ship is converted to a passenger ship. When one passenger gets upset at the inflight entertainment provided by Dr Zoiberg, she yells "Turn down the lights and put on four episodes of ''TheOffice''!"
** That joke could also reflect the fact that many airlines show Office episodes as in-flight entertainment.
* TheOtherDarrin: Two different actresses have played Pam's mom.
** Andy's parents are also portrayed by two different sets of people in "Goodbye, Toby" & "Garden Party".
* ThrowItIn: Many instances, especially in the talking head segments. There's always a complete script, but once the written dialogue has been shot, the actors are free improvise if they wish to do so. According to WordOfGod, Rainn Wilson particularly likes to improvise, noting, "Rainn has never not given an alternate version."
* WhatCouldHaveBeen: Indie darling ZooeyDeschanel was apparently offered a regular role on the show for Season 8, but ultimately turned it down in favor of the lead in the {{Fox}} sitcom ''{{Series/New Girl}}''.
** Will Arnett was seriously considered for the part of the next boss for Dunder Mifflin but was turned down as there were concerns that his new series would conflict with the schedule.
** [[http://www.dailymail.co.uk/tvshowbiz/article-2385635/The-Office-audition-tapes-unearthed-Seth-Rogen-stars-failed-land-job-Dunder-Mifflin.html This article]] shows a few more actors who auditioned, including Seth Rogan for Dwight and John Cho for Jim.
*** One item of interest is that Adam Scott and Kathryn Hahn were considered for the roles of Jim and Pam, respectively. They'd go on to play political rivals and later boss (her) and employee (him) on ''Series/ParksAndRecreation''.
* WrittenByCastMember: Paul Liebestein, Mindy Kaling and B.J. Novak were on the writing staff from the beginning. Steve Carrell later wrote "Survivor Man" and Season 2 finale "Casino Night".
* Several ''Series/TheDailyShow'' alums have appeared on the American version of the show. There are the obvious stars Creator/SteveCarell and Ed Helms, but also Rob Corrdry, Beth Littleford, Rachael Harris, and the aforementioned Wyatt Cenac have had minor roles or were reoccurring characters.
