The Office is a beloved mockumentary-style TV show that aired for over 200 episodes. It was a huge heartbreak to fans once the show was taken off Netflix and moved to NBC's Peacock streaming service. Over the course of its nine seasons, The Office has had an ever-changing cast.
The majority of Dunder Mifflin's original employees make it to The Office's finale. However, notable actors and celebrities make guest appearances throughout the show's run. There are so many guest stars that make a cameo on The Office, it can be difficult for fans to keep track.
10 Idris Elba Plays Charles Miner In The Office
Idris Elba is known for his role as John Luther in the BBC series Luther and Rufus Buck in the latest western film, The Harder They Fall. Before Elba was voted Sexiest Man Alive in 2018, he actually guest-starred for six episodes on The Office.
Elba plays Dunder Mifflin's Vice President, Charles Miner, in the fifth season. While Charles is very discouraging of Michael's immature antics around the office, Elba frequently pranked the cast and joked about his name's pronunciation.
9 Evan Peters Plays Michael's Nephew On The Office
Before becoming a fan-favorite on American Horror Story, Evan Peters played Michael Scott's half-nephew. Peters appears as the lazy Luke Cooper in the seventh season. Michael hires his half-sister's son as an assistant, but viewers quickly realize how incompetent Luke truly is.
Luke messes up errands on purpose and becomes a huge pest to the office workers. One example is how he annoys the Dunder Mifflin office with a laser pointer by pointing it at inappropriate places. His improper tomfooleries eventually cause Michael to yell at him, and Luke angrily quits.
8 Will Arnett Guest Stars On The Office
Will Arnett plays Fred Henry in Search Committee of The Office. He is an applicant for the regional manager position at Dunder Mifflin-Sabre. Fred previously worked as a weather predictor in the Navy while stationed in China.
One of his biggest regrets is sending soldiers to a Mariah Carey concert without coats, because he presumed it would be 70 degrees. Jim doesn't believe Fred when he says he could double their sales. Fred is put on the spot and can't even remember the name of the position or company he applied to work at.
7 Jim Carrey Plays Another Regional Manager Applicant
Jim Carrey makes a brief cameo as another regional manager applicant in Search Committee. Carrey plays Finger Lakes Guy in one of the more confusing roles on The Office.

He says people disappear in Finger Lakes, which is a region in New York, and needs to go back for his family not to worry. A reason why this is mind-boggling for fans is that Phyllis exclaims, "Look, Jim Carrey walked in!" in an earlier season. Did they not recognize him?
6 Ray Romano Plays Merv Bronte On The Office
Ray Romano, a famous stand-up comedian known for his role in Everybody Loves Raymond, also appears on the Search Committee episode of The Office.

Dundler Mifflin employees recognize early how awful it will be to work with him when Deangelo attacks the cake at Michael's going away party.
