Launch Party - S4-E3
Continuity mistake: In 2-13 "The Secret" Pam and Jim are talking about how Jim used to have a crush on Pam when she first started here. This implies that Jim was working here when Pam was hired. However, in this episode Pam says that when Jim first started working there she said, "Enjoy this moment, because you're never going to go back to this time before you met your desk-mate, Dwight." These two scenes contradict each other.
Survivor Man - S4-E7
Continuity mistake: In "The Alliance" (1-4), Pam says that the next office birthday is Meredith's, but it isn't until the next month. Later, in "Survivor Man", it is said that Meredith's birthday is at the end of 'Birthday Month', when many employees have birthdays close together. It wouldn't be possible for Meredith's birthday to both be the next office birthday but also at the end of the following month, which is stated to have many other birthdays in it.
Launch Party - S4-E3
Other mistake: In the beginning of the episode Meredith asks Jim to sign her cast. If you look closely, it's obvious that the actor John Krasinski signs his real name, not the name of his character, Jim Halpert. (00:02:35)
Other mistake: Michael states that he and Jan have traded in their two cars for a Porsche (for her) however from earlier episodes we know that Michael's Sebring is a corporate lease.
Revealing mistake: When Toby announces that he's moving to Costa Rica, he gets up and goes to hop the fence. He moves out of frame and when the camera goes back to him, he's been replaced by a stunt double, which can be seen as the double's face is visible after he's scaled the fence. (00:17:15)
Continuity mistake: When the Dunder Mifflin lawyer says "she thought it had to do with her recent breast enhancement surgery," the woman on the right side of the screen has her hand on her forehead. Then the shot changes angles and the woman's hand is now resting on her chin. (00:08:45)
Revealing mistake: Michael is on his computer trying to open up PowerPoint in front of everyone in the conference room. He says "what we have to do here is go to run" and he clicks the run icon. However on Windows XP (the version he is using) and all other versions of Windows, clicking "Run" would open a separate window where you would type the name of the program. However, what appears on screen is a context menu as if he had clicked the "All Programs" button. You can even see the highlighted "All programs" button indicating that it was actually pressed. They likely had a PowerPoint presentation running in full screen with screenshots of a Windows desktop on each slide. As Steve clicked arbitrarily on the screen, it would trigger the next slide to appear thus creating the illusion that he was interacting with the operating system. (00:19:16)
Launch Party - S4-E3
Revealing mistake: In the first scene, everyone is in the conference room, just waiting for the block on the TV to hit a corner while Michael is blabbing away. The screen has no reflections, but later when Michael talks to the camera there is a reflection. In the scene you can also see the off shading on the characters in it, making it very apparent that the scene was filmed using a green screen.
Branch Wars - S4-E6
Continuity mistake: Earlier in the show we see Michael trying to get Jim to go on a "sale" to crush Utica by pumping him up in the conference room and when he turns to leave he sees Toby in an orange bow tie for The Meeting of the Finer Things Club but later in the episode we see Toby wearing a greenish/brown tie. (00:07:00 - 00:11:00)
Launch Party - S4-E3
Factual error: Michael and Jim are driving from their Scranton, Pennsylvania office to the company's headquarters in New York City for a website Launch Party. However, during the drive, it is clear by looking out the car windows at the mountainous and desert landscape that they are in California, where the show was largely filmed, and not in Pennsylvania, which does not remotely resemble that type of geography.
Launch Party - S4-E3
Continuity mistake: The way the numbers on the sales board are written by Andy change in between shots. (For example, the "305" is written differently, but still "305"; not that it becomes a "380" when Andy changes the number).
Suggested correction: He's only saying it's a corporate lease to egg Dwight on cause he tricked him into thinking he got the manager position over Michael when Dwight tells Jan he could run the branch better in the waffle house, but right after screams "That's my car!" several times.
When he hit Meredith with his car he started it was a corporate lease again though.
Yes, he tells Ryan the accident occurred on company property, with company property so... Double Jeopardy they are fine. To which Ryan says, I don't think you understand how jeopardy works.
