Stars outside the original main cast include Ed Helms, Rashida Jones, Amy Ryan, Mindy Kaling, Craig Robinson, James Spader, Ellie Kemper, and Catherine Tate.

[12] Episodes have been directed by several of the actors on the show including Steve Carell, Rainn Wilson, John Krasinski, B. J. Novak, Ed Helms, Brian Baumgartner, Mindy Kaling and Paul Lieberstein.

[47] The Office was filmed with a single-camera setup in cinéma vérité style to create the look of an actual documentary, with no studio audience or laugh track, allowing its "deadpan" and "absurd" humor to fully come across.

Loosely based on David Brent, Gervais' character in the British series, Scott is a well-intentioned man whose oblivious attempts at humor often offend and annoy his peers and employees, and sometimes draw reprimands from his superiors.

[65] The accounting department includes Angela Martin (Angela Kinsey), an uptight and ultra-religious woman who likes to keep things orderly and make sure situations remain as businesslike as possible; Kevin Malone (Brian Baumgartner), a lovable but dim-witted man who revels in juvenile humor and frequently indulges in gambling; and Oscar Martinez (Oscar Nuñez), who is intelligent and cultured, but often patronizing, and whose homosexuality and Hispanic heritage made him a frequent target of Michael's unintentional off-color comments.

Rounding out the office are the laconic salesman Stanley Hudson (Leslie David Baker), who cannot stand Michael's constant references to his Black American heritage (he also does not like to take part in time-wasting meetings and often solves crossword puzzles or sleeps during them); the matronly saleswoman Phyllis Lapin (Phyllis Smith), who dates and then marries Bob Vance (Robert R. Shafer) from Vance Refrigeration, a company whose office is across the hall from Dunder Mifflin; eccentric quality assurance representative Creed Bratton (Creed Bratton), who has a mysterious criminal history; Andy Bernard (Ed Helms), a salesman from the Stamford, Connecticut branch of Dunder Mifflin introduced in season three who transfers to the Scranton branch after the two offices merge; Karen Filippelli (Rashida Jones) a short term love interest for Jim also from Stamford; the shallow and talkative customer service representative Kelly Kapoor (Mindy Kaling); the promiscuous alcoholic supply relations representative Meredith Palmer (Kate Flannery); human resources representative Toby Flenderson (Paul Lieberstein), who is loathed, and often the target of abuse, by Michael; warehouse foreman Darryl Philbin (Craig Robinson); warehouse dock worker and Pam's fiancé Roy Anderson (David Denman), who is fired in the third season for attacking Jim; and the vice president for regional sales for Dunder Mifflin Jan Levinson (Melora Hardin), who later becomes Michael's rather toxic love interest.

Toward the end of season five, the bubbly and naive Erin Hannon (Ellie Kemper) is introduced as Pam's replacement at the reception and develops a unique bond with Michael when he becomes almost a father figure in her life.

The series starts by introducing Dunder Mifflin's employees via a tour given by branch manager Michael Scott for both a documentary camera crew and first-day temp Ryan Howard.

[81] Salesman Jim Halpert has a crush on receptionist Pam Beesly, who helps him play pranks on co-worker Dwight Schrute, even though she is engaged to Roy Anderson, who works in the company's downstairs warehouse.

Transferred to the Scranton branch are saleswoman Karen Filippelli, whom Jim has begun dating, and the anger-prone preppy salesman Andy Bernard, along with other Stamford employees who all eventually quit within the first few episodes of being there.

[88] NBC ordered a fourth full season of thirty half-hour episodes but ended with only 19 due to a halt in production caused by the 2007–2008 Writers Guild of America strike.

[91][92] A self-employed Jan moves herself and her candle business into Michael's condo, until the dissolution of their relationship midway through the season during an intimate dinner party including Pam, Jim, Andy, Angela and Dwight.

[99] Meanwhile, Andy and Erin develop an interest in each other, but find their inherent awkwardness inhibits his attempts to ask her out on a date during a murder-mystery game meant to distract the members of the office.

[107] Dwight is tasked with traveling to Tallahassee, Florida, to assist Sabre special projects manager Nellie Bertram (Catherine Tate) in launching a chain of retail stores, along with Jim, Ryan, Stanley, Erin, and new office temp Cathy Simms.

Andy, recently returning from Outward Bound manager training, reverts to his arrogant earlier season personality, abandoning both Erin and the office to travel around the Caribbean with his brother in their sailboat after his parents' relationship's demise.

Dwight receives more good news when David Wallace handpicks him to be the new manager after Andy quits to pursue an acting career, which quickly ends when he embarrasses himself at an American Idol-like a cappella singing competition that turns into a viral web sensation.

Jim and Pam, at her persuasion, move to Austin, Texas to open a new branch of Athleap (previously Athlead) with Darryl (Dwight "fires" them to give them both severance packages), and Creed is arrested for his many crimes.

[113][114][115] Though not an explicit product placement, the producers of the show had to allow Chili's to have final approval of the script before filming, causing a scene of "The Dundies" to be hastily rewritten when the chain objected to the original version.

[117] The travel website TripAdvisor was featured during Season 4 when after a visit to Dwight's "agritourism" bed and breakfast, Schrute Farms, Jim and Pam post an online review about their stay.

"[123] A Guardian Unlimited review panned its lack of originality, stating that Steve Carell "just seems to be trying too hard.... Maybe in later episodes when it deviates from Gervais and Merchant's script, he'll come into his own.

"[124] Tom Shales of The Washington Post said it was "not the mishmash that [the Americanized version of Coupling] turned out to be, but again the quality of the original show causes the remake to look dim, like when the copying machine is just about to give out.

James Poniewozik of Time remarked, "Producer Greg Daniels created not a copy but an interpretation that sends up distinctly American work conventions ... with a tone that's more satiric and less mordant...

[149][150] In an IAmA interview on Reddit, Rainn Wilson felt that the eighth season possessed some mistakes "creatively," such as the chemistry between Spader and Helms, which he called "a bit dark" and argued that the show should have gone for a "brighter and more energized" relationship.

Cast appearances were made by B. J. Novak, Ed Helms, Oscar Nunez, Angela Kinsey, Brian Baumgartner, Leslie David Baker, Mindy Kaling, Craig Robinson, Melora Hardin, Phyllis Smith, Creed Bratton, Kate Flannery, Bobby Ray Shafer, and Andy Buckley.

Besides Novak and Kaling, writer appearances were made by Greg Daniels, Michael Schur, Jennifer Celotta, Lee Eisenberg, Gene Stupnitsky, Justin Spitzer, Anthony Ferrell, Ryan Koh, Lester Lewis, and Jason Kessler.

"The Office," said The New York Times, "is on the leading edge of a sharp shift in entertainment viewing that was thought to be years away: watching television episodes on a computer screen is now a common activity for millions of consumers."

Other merchandise, from T-shirts and a bobblehead doll of Dwight Schrute[240] to more office-specific items such as Dunder Mifflin copy paper[241] and parodies of the Successories motivational poster series featuring the cast[242] are available.

[261][263] In September 2019, with the announcement of NBCUniversal's streaming service Peacock, Bonnie Hammer, Chairman of Direct-to-Consumer and Digital Enterprises at NBCU stated that it is her "hope and goal that we do an Office reboot".

[271] The follow-up, to be available for streaming on Peacock, will center around the documentary crew from the original series finding a new subject in a dying Midwestern historic newspaper and the publisher trying to revive it with volunteer reporters.

The follow-up has Daniels, Michael Koman, Howard Klein, Ben Silverman, Banijay Americas and the creatives behind the original British series (Ricky Gervais and Stephen Merchant) on board as its executive producers.
