So many wonderful characters have graced the offices of Dunder Mifflin in NBC’s The Office. It remains one of the best casts to ever appear on televisions. Through its nine seasons on the air, the show also featured some very memorable guest stars like Will Ferrell, Amy Ryan, and Idris Elba.

However, there are some well-known faces you may have forgotten appeared alongside Michael, Dwight and the rest of the gang. Their stays at Dunder Mifflin may not have been long, and they found their fame elsewhere, but it’s still fun to look back and say, “Oh cool, they were in that.” Here are some of the actors you forgot appeared on The Office.

10. Amy Adams

Amy Adams as Katy Moore in The Office

In the very first season of the show, The Office was joined by a pretty great guest star, Amy Adams. Playing Katy, Adams first appeared in the episode “Hot Girl” as an attractive woman trying to sell handbags to the office. Of course, Michael makes a fool trying to flirt with her until she ultimately leaves with Jim.

Adams returned for two more episodes in Season 2 before her relationship with Jim ended and she was seen no more. Adams career did just fine afterwards, securing a handful of Oscar nominations and even joining the DCEU as Lois Lane.

9. Ken Jeong

Nowadays, Ken Jeong is a regular face in comedies. But back in 2005, Jeong was a working stand-up comedian taking small roles in sitcoms. In the second season episode “E-Mail Surveillance”, Jeong had a small role as a member of Michael’s improv group. Yet another person who struggled to put up with Michael’s obnoxious behavior.

It was a small role, but Jeong’s success was right around the corner with memorable roles in Knocked-Up and The Hangover. Jeong recently appeared in the highly successful movie, Crazy Rich Asians and his Netflix special out now.

8. Jack Black

Jack Black was already a big star when he appeared in Season 5 of The Office. In fact, he was so famous, he was able to play himself. In “Stress Relief”, Jim, Pam, and Andy spend the day watching a movie in the office breakroom. Black stars in the fictional film in which he has an affair with Cloris Leachman.

It’s a bit of a bizarre cameo and felt a little like the show just wanted to have a big name. While the movie-watching plot is pointless, Black and Leachman seem to be having a good time.

7. Evan Peters

Evan Peters has the great distinction of being the only member of Michael Scott’s family we see on the show. His character also shows that Michael probably isn’t the most annoying member of his family.

In Season 7’s “Nepotism”, Peters plays Michael’s nephew Luke who has been hired as the office intern. Luke is hardly a model employee, but Michael is hesitant to fire him. All this leads to a very memorable disciplinary scene which explains why we never see Luke again.

Peters would later gain acclaim as Quicksilver in the X-Men films and will reprise the role in Dark Phoenix.

6. Timothy Olyphant

Timothy Olyphant is an actor mostly known for his tough guy roles in shows like Deadwood and Justified. However, in Season 7 of The Office, Olyphant got the chance to show off some of his comedic work.

In two episodes, Olyphant played Danny Cordray, the best salesman in the business who Michael hires as the office’s traveling salesman. Things immediately get awkward since he once went on a date with Pam but never called her back.

Olyphant is currently embracing his comedic side in Santa Clarita Diet, he’ll be seen in Tarantino's Once Upon a Time in Hollywood and will return as Seth Bullock in the Deadwood movie.

5. Jim Carrey

The Season 7 finale “Search Committee” centered around trying to find a new boss for the Scranton office. The episode featured several famous guest stars playing the various unusual characters vying for the regional manager position, including Will Arnett and Ray Romano. But the biggest guest star was certainly Jim Carrey.

Carrey plays an unnamed job interviewee who seems to have a strange obsession with the Finger Lakes. It’s a fun, albeit short cameo for Carrey to pop up. It’s just a shame we didn’t get to see him in the actual interview, as that could have provided a few laughs.

4. Randall Park

The great Randall Park is delight anytime he pops up. In 2018 alone, he was joined the MCU in Ant-Man and the Wasp, and the DCEU in Aquaman. In The Office, Park had the honor of being a part of one of Jim’s famous pranks.

In Season 9’s “Andy's Ancestry”, Park plays an actor friend of Jim and Pam who they get to pretend to be Jim. This causes Dwight to wonder if he never noticed the fact that Jim has always been an Asian man. Certainly one of Jim’s most underrated pranks.

3. Bob Odenkirk

The later seasons of The Office suffered from the absence of Steve Carell. In Season 9’s episode, “Moving On” they tried to fill that void a little with the help of Bob Odenkirk.

In the episode, Pam is looking for a new job in Philadelphia. Odenkirk plays her potential new boss and a man who is a carbon-copy of Michael Scott. What makes the joke even better is the fact that Odenkirk was one of the finalists for the role of Michael Scott. Of course, he went on to find the role of a lifetime with Saul Goodman.

2. Roseanne Barr

Roseanne Barr has had a few ups and downs in her career recently, to say the least. Luckily, her appearance on The Office came at a relatively quiet period. Before the reboot of her sitcom and her subsequent firing from it, Barr guest starred on two episodes in the final season as talent agent Carla Fern.

In the show, Andy decides to finally pursue his show business dreams and hires Carla to help him. The role wasn’t very big, but it was at a time when it was just nice to see Barr on television again. How things have changed since then.

1. Dakota Johnson

The final episode of The Office was a big deal. After nine seasons of the show, they had to wrap up many storylines, bring back several characters and close things out in a satisfying way. With all that going on, you’d be forgiven for failing to notice Dakota Johnson’s small role.

Johnson plays one of the new employees in the office and her relationship with Clark, another member of the office is meant to suggest a Jim and Pam-type romance is blooming. Just two years later, Johnson would become a household name thanks to Fifty Shades of Grey.
