It’s Always Sunny: 10 Most Popular Cast Members, Ranked By Instagram Followers

FX’s It’s Always Sunny in Philadelphia continues to be a massively successful sitcom. Its ever-growing fanbase is always eager to see the gang’s wild antics with every new season. With the recent premiere of season 15, viewers are likely checking out the cast members’ social media in between episodes.

Whether it’s to see behind-the-scenes shots or simply to keep up with the celebrities’ lives, fans can learn a lot about the show’s lovable cast through their Instagram accounts. Some of them have an impressive following, with Charlie Day and Rob McElhenney each having well over a million followers.

Brian Unger (7K followers)

Simply known as The Lawyer, Brian Unger plays a fan-favorite role as one of the best recurring characters in It’s Always Sunny. He shows up every now and then and faces off against the gang, using his real-life knowledge of the law despite Charlie’s obvious expertise on bird law.

Unger’s Instagram account paints a totally different picture of who he is compared to his character. Instead of constantly plotting his revenge, Unger keeps himself busy by focusing on fitness, often posting photos of him going horseback riding or practicing CrossFit. He does give fans a chance to see his character outside of the show through his TikTok videos, which feature him giving advice to strangers in funny ways.

Lance Barber (26k followers)

It’s safe to say that Bill Ponderosa’s (Lance Barber) relationship with the gang isn’t exactly healthy. He used to be a fit and ambitious person in high school but eventually became addicted to drugs and alcohol. Every attempt at overcoming his addictions is foiled by the gang.

On Instagram, Barber has humorous posts that show him in silly costumes. His feed is overwhelmingly full of loving photos with his family, though, as he seems to enjoy sharing pictures from their trips or even just dinners at home. Fans will also spot behind-the-scenes images from his other TV show, Young Sheldon.

Artemis Pebdani (32.5k followers)

Most fans would agree that Artemis Dubois deserves to join the gang, as she’s one of the best side characters on the sitcom. Played by Artemis Pebdani, she confidently goes along with the group’s wacky antics since she can be just as wild as the rest of them. Fans may recall how she boldly steals Dee’s potential love interest after posing as his pen pal.

Pebdani’s Instagram feed rarely features her face and only occasionally shows behind-the-scenes photos with the gang. Instead, she focuses on sharing images calling for donations for people in need or promoting important advocacies. There are also the sporadic coffee appreciation photos, which show she has an appreciation for the drink.

Jimmi Simpson (115k followers)

Jimmi Simpson plays the role of Liam McPoyle, who is arguably the most recognizable among the McPoyle siblings. One of many run-ins with the gang leads to his eye getting pecked by a bird, which helps him create his now-iconic eye patch look.

Fans may be surprised to see a different side of the character, who’s an experienced actor who appeared in shows like Black Mirror, Westworld, and House of Cards. Simpson often posts glamour shots of himself, as well as videos of him taking walks in parks or exercising. Fans who scroll far enough will spot some old behind-the-scenes pictures with Day and other cast members from It’s Always Sunny.

David Hornsby (120k followers)

Played by David Hornsby, the fan-favorite Rickety Cricket is perhaps the gang’s most unfortunate victim. His infatuation with Dee leads him down a rabbit hole of constant abuse, addiction, and eventually, homelessness. His steady spiral over the past few years is almost too painful to watch, but episodes that feature him somehow always end up being ridiculously gut-busting.

Hornsby’s Instagram feed is far from what fans would expect from a character like Cricket. He often shares behind-the-scenes photos from his other project, Mythic Quest, where he continues to work with Day and McElhenney. There are also numerous images of Hornby’s art, as he regularly attends classes to improve his figure and life drawing skills.

Mary Elizabeth Ellis (319k followers)

Known simply as The Waitress, Mary Elizabeth Ellis plays the role of a burnt-out acquaintance of the gang, who often struggles to make ends meet and has to work several jobs to survive. Charlie’s unhealthy obsession with her is obvious from the first moment they meet, as she accuses him of stalking her and even eventually files a restraining order against him.

Fans may already know that Day and Ellis are actually married in real life, which is what she often posts about on her Instagram account. Viewers will see several photos of the gang in Paddy’s Pub on her feed. Ellis also posts fitness and travel content every now and then, giving fans a glimpse into what she does on a daily basis.

Glenn Howerton (715k)

Played masterfully by Glenn Howerton, Dennis Reynolds often does the worst things in the sitcom. He’s extremely narcissistic and does not care at all about other people’s feelings. In fact, he goes out of his way to hurt and manipulate others at times, especially if they’re women he intends to sleep with.

Howerton’s Instagram account is full of promos and behind-the-scenes shots from the show. His more laidback side is seen in the several images that show him lounging with his dog or having a beer. Older photos highlight his love for traveling, skiing, and even ATV riding!

Kaitlin Olson (804k followers)

Dee Reynolds (Kaitlin Olson) is Dennis’ sister and usually the unfortunate subject of jokes among the gang. She’s often ridiculed for looking like a bird and her ideas are dismissed as being senseless, even though she sometimes comes up with rational ones. Still, she can be just as zany as the crew, in large part due to her unfulfilled dream of becoming an actress.

Fans who scroll through Olson’s Instagram feed may be surprised to learn that she’s married to McElhenney, whom her character sometimes butts heads with on the show. Aside from behind-the-scenes photos, Olson regularly posts images of her family, which include McElhenney, their two kids, and several pets.

Rob McElhenney (1.1M followers)

McElhenney plays the likable Ronald “Mac” McDonald on It’s Always Sunny. He’s supposedly the bouncer for Paddy’s Pub, but he spends most of his time coming up with wacky business ideas with the gang. He’s obsessed with his self-image and often projects a tougher version of himself when hanging out with his friends.

On McElhenney’s Instagram account, fans will see a lot of the same posts from his wife’s feed, which include behind-the-scenes photos and promos for the show. He has a great sense of humor and doesn’t shy away from posting wacky self-portraits. There’s also no shortage of content centered on his other project with Day, Mythic Quest.

Charlie Day (1.5M followers)

Known as the wacky janitor of Paddy’s Pub, Charlie Kelly (Day) is not exactly the smartest member of the gang. His illiteracy has gotten in the way of several schemes, although he’ll never admit that he struggles to read and write. Frank does nothing to discourage Charlie’s dysfunctional behavior, nor do the rest of the group. They don’t seem to mind that Charlie is often high-strung and stressed out by having to deal with their antics and making sure the bar is decent enough to stay open.

Despite having the largest following, Day has the fewest posts on Instagram, having only 36 images on his feed. His posts mostly consist of behind-the-scenes images and promos for the show. Fans will likely be more excited about his photos with his wife, who plays The Waitress on the sitcom.
