- First ever NBC comedy series on NBC to be presented in wide-screen to non-HDTV viewers, resulting in horizontal black bars. Previous NBC dramas have been presented in wide-screen to non-HDTV viewers, but no previous comedy.
- Dwight currently has four bobble-heads on his desk. The most well known is the "Dwight Schrute" bobble-head, a present from Angela in season two. Two others seen throughout the series are of Mike Lieberthal and John Kruk. Lieberthal played catcher for the Scranton/Wilkes-Barre Red Barons before being promoted to the Philadelphia Phillies and John Kruk was a Philadelphia Phillie before retirement. The fourth bobble-head, added in the fourth season, is of former Syracuse University guard and Scranton native son Gerry McNamara.
- Dwight has a "Froggy 101" bumper sticker on the filing cabinet next to his desk. Froggy 101 is the #1 rated country-western station in Scranton, Pennsylvania, the setting for the show. This bumper sticker can also be seen in the office of Michael's boss at his short-lived night job at the telemarketing company.
- Many of the famous insert shots from the original series such as the water cooler and copier machine are not used in the show. Instead they pay homage to those particular shots by placing them in the opening credits.
- The exterior shot of the building the office is "in" in Scranton, Pennsylvania is across the street from a bar which is coincidentally named "The Office". Greg Daniels has said that he hopes this is a sign of good karma for the show. The Office (the bar) was actually condemned by the city a few years back.
- The first season was filmed in actual office space located just above a sound-stage. The sound-stage is often used to replicate the Dunder-Mifflin warehouse, most notably in the "Basketball" episode. For the second season, an exact set replica of the original office was built on a sound-stage for further shooting.
- Michael has a Union Jack Flag on his desk that appears in various shots as a homage to the original British series.
- The computers on the Dunder-Mifflin office set are wired for the internet. Cast members have admitted that when they're in the background of scenes they are often checking email and surfing the net.
- Four of the regularly appearing secondary characters have the same first name as the actress or actor that plays her or him: Angela (Angela Kinsey), Oscar (Oscar Nuñez), Phyllis (Phyllis Smith) and Creed (Creed Bratton).
- The Office's address is 1725 Slough Road. Slough was the name of the town in which the original version of the show takes place. However, there is no Slough Road in Scranton.
- Many main and supporting cast members have written episodes of the show. B.J. Novak (Ryan), Paul Lieberstein (Toby) and Mindy Kaling (Kelly) wrote 12 of the 28 episodes over the first and second seasons (albeit separately). (Liberstein would even go on to direct a fourth season episode, "Money".) Steve Carell (Michael Scott) has written two episodes so far: "Casino Night" (which was the second season finale) and "Survivor Man". One episode (2.8, "Performance Review") was written by Larry Wilmore, who plays Mr. Brown, the diversity instructor. Michael Shur, a seasoned writer, plays Dwight's cousin Mose Schrute. Gene Stupinsky and Lee Eisenberg, two writing partners, play the delivery men in the Valentine's Day episode and others. Greg Daniels, the developer and show runner of the Office, played Michael's neighbor in "Office Olympics" but his scene was cut.
- Four of the main cast members are originally from Massachusetts: Steve Carell (Michael Scott), John Krasinski (Jim Halpert), B.J. Novak (Ryan Howard) & Mindy Kaling (Kelly Kapoor). Guest star Nancy Walls (Carol Stills), Steve Carell's real-life wife, is also from Massachusetts.
- John Krasinski and B.J. Novak went to high school together. They went to Newton South High School in Newton, MA and they both graduated in 1997.
- Both Brian Baumgartner (Kevin) and Ed Helms (Andy) graduated from The Westminster Schools in Atlanta, Georgia.
- Some of the video used in the opening theme song specifically the exterior shot of the building was taken by John Krasinski and his friends in their Jeep. John had just gotten the part and was coming out for shooting.
- Matt Walsh was in the final running for the Dwight role but was turned down.
- Michael's birthday is March 15th.
- The cast is frequently seen on-screen drinking cans of Crystal Club soda (various flavors, Jim seems to prefer their cola), which is made in Scranton by the Crystal Club Soda Water Company.
- There is an actual lamp banner in Scranton, PA of the fictional company Dunder Mifflin on N. Washington Ave. It had to be replaced once after being stolen.
- Poor Richards Pub, a bar the gang often refers to in the show, is an actual bar in South Scranton. It is actually in a bowling alley, South Side Lanes.
- Steve Carell only watched a few minutes of the British version before permanently stopping such viewing because he did not want to copy Ricky Gervais' performance as the office manager. John Krasinski, on the other hand, was an avid viewer of the original.
- Michael Scott has a "Certificate of Authenticity" on his wall that states he is the "Proud Owner of a Quality Seyko Timepiece."
- There are some changes in the set between the first season and the subsequent ones. The exterior of the building is completely different in the first season than what's used after. Also, the wall in between Michael's office and the conference room (the one Andy punches a hole in) is much thinner in the first season. Also in the first season there is a door to the left of the break room door that disappears, and above Creed and Merideth's desks. Now there is just a door between Creed's desk and Oscar, Kevin's, and Angela's island.
- The document being highlighted in the opening credits scene is a copy of the Los Angeles Municipal Code, Section 12.22.
- The show had to stop production in November 2007 because of a writer's strike. The show's star Steve Carell (himself a WGA member) supported the writers, and refused to cross the picket lines even for non-writing duties. Carell went so far as to call in sick to the network on the first day of the strike, citing a case of "enlarged balls" as the reason he couldn't come in.
- The "Welcome to Scranton" sign featured in the opening credits, formerly located on the Central City Expressway, is now on display in the food court of the Mall at Steamtown. It is setup with a backdrop so people can get their picture with it. It was moved there when the city replaced the signs with new signs.
- The Penn Paper building featured in the opening credits is located at 215 Vine Street in Scranton, PA, which is about one block from Mifflin Ave. This is likely where the fictional company name "Dunder Mifflin" came from. The "Penn Paper" sign on the building has now been replaced by "PA Paper" in blue lettering.
- Fictional company Dunder Mifflin is now an actual member of the Greater Scranton Chamber of Commerce.
- It is frequently mentioned that the characters Phyllis Lapin Vance and Michael Scott are the same age, having gone to high school together. In real life Phyllis Smith is 11 years older than Steve Carell.
- Michael Scott's home address is shown as either 42 Kellum Court (per NBC's Dunder Mifflin website) or 126 Kellum Court (seen on the show). Kellum Court is a real street in Scranton, but house numbers start at 300 because of the city block numbering system. If it existed, the physical location of 42 Kellum Court would actually be in the rock quarry depicted behind the "Scranton Welcomes You" sign in the opening credits.
