The Office featured some of the world's most reputable actors in its nine seasons. Impressively, The Office has included the likes of Will Ferrell, Dakota Johnson, and Stephen Colbert. Although the comedy TV series was an adaptation of the UK version, The Office US evolved into its own. It featured office relationships, hilarious situations, and more relatable characters.

The Office boasts a talented cast of established actors who come and go. Guests stars are often used as minor characters, some of which are only seen in one episode. Sometimes viewers quickly become attached to these beloved individuals. It feels like some characters didn't get enough air time or may have left The Office too soon.

10 Hank Doesn't Get Enough Credit

The late Hugh Dane plays Hank Tate, the building's security guard. He briefly appears in times of need, escorting former employees from the building or rescuing staff trapped inside the parking lot. Hank's character is generally underappreciated and his moments on-screen are short, but his lines are delivered perfectly.

Hank generates humor with his carefree attitude and laid-back manner. It's these traits that make his character very likable which should have been integrated more. He's not overly fond of his job. Seeing more of Hank participating in activities after work would have allowed his character to flourish.

Mose struggles socially which may be a result of rarely leaving the beet farm. The reason he lives with Dwight could be because of his child-like mannerisms - he has frequent nightmares and a fear of paper. With many unanswered questions surrounding this character, viewers were expecting to see more of Mose throughout The Office.

8 Glove Girl Could Have Dated Michael

In Blood Drive, it's Valentine's day in Scranton. Michael generously decides to donate his blood. Inside the mobile blood drive van, there's a mysterious lady also donating. Despite being nervous, they effortlessly make conversation to take their minds off the needles. Viewers are fooled into thinking that this relationship will blossom, but Michael passes out seconds after the procedure.

When he regains consciousness, Michael realizes that the lady forgot her glove and he desperately tries to turn the situation into a Cinderella story. If she had been in more episodes, she and Michael could have started dating. The nameless lady is known only as "Glove Girl."

7 Danny Cordray's Character Was Fizzled Out

Timothy Olyphant as Danny Cordray from The Office US

American actor, Timothy Olyphant, plays the part of Danny Cordray. He's a shark at sales who works for Dunder Mifflin's competitor, Osprey Paper. He makes his debut in season 7 during The Sting. He has a fierce reputation and intimidates others with his good looks and charming confidence.

Michael poaches Cordray and employs him as a traveling salesman. Michael realizes the company already has a man on the road. Because of this, and perhaps Olyphant's high demand, Cordray is fizzled out. Considering he owns his own bar in Scranton, he could have easily been incorporated later in The Office despite no longer being a Dunder Mifflin employee.

6 Brian The Boom Guy Breaks The Fourth Wall

Surprisingly, viewers are first introduced to the film crew's boom operator, Brian, towards the end of The Office in season 9, episode 12. The Office's favorite couple have a bad day. Jim deals with work problems in Philidelphia and Pam fails to capture Cici's dance recital.

As the two abruptly end their phone conversation, the scene is interrupted by Brian who comforts Pam. This act breaks the fourth wall and Brian demands the crew stops filming. After years of being behind the scenes, fans are keen to know more about Brian's involvement throughout The Office and his influence on other characters. Brian is integrated into the storyline episodes later, but The Office soon comes to an end.

5 Charles Miner Has A Higher Level Of Professionalism Than Most

Idris Elba as Charles Miner from The Office US

Renowned English actor, Idris Elba, portrays Charles Miner. He was introduced to The Office in season five. He replaces Ryan Howard as the company's vice president in New Boss. As a corporate employee, he has authority over everyone in the office, and a higher level of professionalism than most.

With viewers used to the usual office antics, Charles was like a breath of fresh air on The Office. However, other than his love for soccer, fans knew very little about this authoritative figure. The Office could have shown more of Charles' time in Scranton including outside-of-work activities with other protagonists.

4 Jessica And Andy's Initial Dates Could Have Been Shown

Jessica from The Office

In the finale of season 6, Andy and Erin's relationship quickly ends. It is not confirmed when Andy and Jessica started dating, but it is revealed later in season 8 Spooked. Andy claims that he'd been with Jessica for a while, and the two had been on a total of 31 dates.

These intimate meetings happened off-camera and the development of their serious relationship is not shown. Witnessing the initial stages of their relationship, including the first meet, would have allowed viewers to be more familiar with Jessica's character. She is friendly and smart which could have led to closer friendships with other members of the office.

3 Todd Packer Adds A New Dynamic To The Show

Traveling salesman, Todd Packer, is played by well-known actor, David Koechner. Before the film crew started making the documentary, Michael and Todd were good friends and worked together as salesmen. As a result, the two of them have a close relationship, despite Packer's vulgar and arrogant manner.

Due to his crude jokes and inappropriate behavior, he is not liked among the rest of the office workers. However, his character adds a new dynamic to The Office. In the seasons prior, Packer's methods and sales techniques are unknown. Seeing what he got up to in between jobs could have added another level of humor to The Office.

2 Katy Is Liked By Most Characters And Viewers

Amy Adams as Katy Moore from The Office US

Handbag vendor Katy Moore arrives on the scene in Hot Girl during the first season. Katy is played by American actress, Amy Adams, who has played the lead role in movies such as Enchanted and ArrivalKaty is also Jim's first girlfriend in The Office. However, their relationship comes to a disappointing end in the following season.

Katy is liked by most characters and viewers, so her early departure from The Office could have been avoided. After her break up with Jim, a different dynamic could have blossomed with another office goer or warehouse worker. This would have maintained her presence in The Office despite not being a Dunder Mifflin employee.

1 Luke Cooper Is Only Seen In One Episode

Evan Peters as Luke from The Office US

American Horror Story star, Evan Peters, plays Michael Scott's Nephew, Luke Cooper. He makes his first and only appearance in the premiere of season seven. He is hired as the office assistant and can't seem to execute any of his tasks correctly. As a result, Luke easily annoys his peers and lacks both drive and valuable work experience.

Although the other employees don't warm up to him, his energy and immaturity briefly brought something new to the office environment. Had he been included in future episodes, he would have likely developed a basic work ethic and integrated more with other characters. Even though Jo Bennet disapproves of hiring family members, viewers weren't ready to say goodbye to this misunderstood individual.
