Jenna Fischer and John Krasinsi met for the first time during casting andthere was almost immediate chemistry. The producers held a series of casting sessions with different actors playing Pam and Jim. Jenna Fischer said John Krasinski was her favourite Jim, while Krasinski responded that she was his favourite Pam. When each was offered the part, the first thing they asked was if the other got the part.
John Krasinski shot the footage of Scranton that appears in the show’s opening credits from his jeep when he and a few friends cased the city before he began shooting.
Sometimes the byplay between the actors was so hilarious even they couldn’t hold back a laugh. When Michael was dressed as Santa and made Kevin sit on his lap, you can see Mindy Kaling and Ed Helms trying not to laugh. And finally, after several shots in which the exercise ball Rainn Wilson was sitting on deflated slowly, John Krasinski stabbed a seam causing Wilson to hit the floor hard. You can see Krasinski jump out of the shot because he was laughing so hard that he had tears in his eyes.
Producers originally wanted John Krasinski for the role of Dwight Shrute but he refused to even read for the part insisting he would make a much better Jim Halpert.
The computers on the set were real andconnected to the internet. Cast members confessed that they often surfed the web or answered emails while they were at their desks in the background.
Steve Carrell confessed that he lied for months to the press, to executives, to everyone about his participation in the final episode of The Office. They even kept the secret from NBC executives. They made Creed read Micheal's lines during script reading. Carrell’s “That’s what she said”, response to Dwight’s “I didn’t think you would come” in the wedding scene is one of the best uses of his go-to phrase.
Phyllis (Phyllis Smith), Angela (Angela Kinsey), Creed Bratton (Creed Bratton) and Oscar (Oscar Nunez). These characters shared the first names of the actors who play their role.
Micheal had a fishbowl in his desk but the fish change each episode. In season 5 during the first episode, it is a goldfish, in the second episode the fish is called calico and in the third episode, it is a blackfish.
The producer's grandparents were beet farmer so Dwight became a beet farmer.
Actor Rainn Wilson actually createda blog called Shrute Farm Beets for his character Dwight.
