Why So Many Shameless Actors Quit The Show

Showtime's "Shameless" achieved what few shows can do successfully. It seamlessly paired slapstick comedy with dramatic elements that tugged at the heartstrings of many, particularly those who grew up (or are still) part of the United States' working-poor class. Before it aired on Showtime in 2011, "Shameless" had already gained a substantial following on BBC. The British version aired from 2004 to 2013 and was executive produced by Paul Abbott.  Abbott created the series to depict his real-life family, who were raised by his 16-year-old sister, whom Abbott has shared was pregnant with her own child when she took on caring for him and his seven child siblings. 

The U.K. series' success may have gotten the U.S. version of "Shameless" in the door, but its star power kept it thriving for 11 seasons, from 2011 until 2021. Throughout its run, many fans quickly fell in love with the wild and crazy cast of Gallaghers – Frank (William H. Macy), Fiona (Emmy Rossum), Lip (Jeremy Allen White), Carl (Ethan Cutkosky), Ian (Cameron Monaghan), Debbie (Emma Kenney), and Liam (Christian Isaiah) — as well as many of the Gallaghers' chosen family, especially their loyal next-door neighbors, Kevin "Kev" Ball (Steve Howey) and Veronica "V" Fisher (Shanola Hampton). The characters felt like a genuine family each week, which was a testament to the close bond the cast members share in real life. Unfortunately, not everyone in the Gallaghers' world stayed around forever. Find out why some of the most popular "Shameless" actors quit the show. 

The first season of "Shameless" was surely a sight to see. Airing on Showtime on Jan. 9, 2011, the characters quickly earned their keep in making the show's name as accurate as possible. As we met the Gallaghers, we also met some of the equally brash company they keep. One of the early standout characters came in Season 1 through Mandy Milkovich (Jane Levy), the feisty younger sister to one of the Southside's criminals, Mickey Milkovich (Noel Fisher). Mandy initially had a crush on Ian (Monaghan), and expressed as much early on, which Levy recalled. "My first scene I ever did was me pouncing on Cameron Monaghan and taking his pants off, essentially pretending to go down on him," Levy explained in an interview with Backstage. "My first scene ever, ever, ever."

The actress's time on "Shameless" marked her first time on TV, though she would soon find a bigger opportunity was awaiting her. After just one season as Mandy, Levy quit the show to star in "Suburgatory." In the NBC series, Levy played Tessa Altman, a teenager forced to live in the suburbs after her father, George Altman (Jeremy Sisto), finds a box of condoms underneath her bed. While speaking about the role she starred in for three seasons in 2012, she said she related to the character based on her own carefree teen years. Emma Greenwell later took over playing Mandy after Levy's departure.

On "Shameless," Fiona had many, many ill-fated relationships. She was the matriarch of her family and prioritized her siblings, which often didn't leave enough room to assess the men who came her way. Seasons 1-3 of "Shameless" focused on Fiona's topsy-turvy relationship with "Jimmy/Steve," played by Justin Chatwin. Jimmy/Steve was trouble from the start, as he revealed he's a luxury car thief in Season 1. By Season 2, he proves he's even less trustworthy when Debbie tells Fiona she found out that "Steve's" real name is Jimmy Lishman, hence the "Jimmy/Steve" nickname. Somehow, the pair made it through his deceit, only for him to disappear again in Season 3. The disappearance came after his wife, Estefania (Stephanie Fantauzzi), was taken into immigration custody after she was unable to reach him. Fiona tried to reach Jimmy/Steve but, after several failed attempts, left him a farewell voice message and focused on a fresh start, which included a new job and a boyfriend (and her boss), Mike Pratt (Jake McDorman).

Chatwin's exit from "Shameless" didn't seem to be his idea. His character was written off the show, which was something showrunner John Wells deemed necessary, stating in a 2013 interview that he felt the character's story arc had come to an end. To the audience, and even Chatwin, Jimmy/Steve was presumed dead, with the audience thinking Estefania's father killed him. However, the character returned in Season 5, this time coming in between Fiona's marriage.

For many "Shameless" fans, it just isn't the same without all of the core Gallaghers bonding together at home. That would prove to be less of the case as the series went on, as some of the main cast members, including Monaghan, explored what life could look like outside of the series. In 2019, after eight years of playing Ian — a character who was acclaimed for his storylines, including him being a gay man living with bipolar disorder — he decided to leave the series during Season 9. Monaghan's final episode aired in October 2018, where his character faced his final day before his prison sentence for blowing up a van during his "Gay Jesus" story arc in Season 8. The episode ended with Ian and Mickey reuniting in prison.

Monaghan later told reporters at the 2018 Television Critics Association's winter press tour that he decided to quit "Shameless" due to "creative reasons as well as business, which many other actors had done on the show years earlier." However, just four months after his exit, he returned to the series and remained as a central character until the show wrapped in Season 11. Monaghan explained his quick return came after he "talked to showrunner John Wells about possible things we could do with the character in the future, and we go to a place both creatively and financially where I felt comfortable coming back...I'm excited to go back and do that."

Noel Fisher's recurring role as Mickey Milkovich undoubtedly created some of the most iconic "Shameless" moments in the show's history. Mickey and Ian's love story earned the characters the adorable ship name "Gallavich" and evolved into one of the show's few couples who ended up lasting forever. However, their ending almost ended far too soon when Fisher left "Shameless" at the end of its fifth season. Mickey's character arc temporarily ended when he escaped to Mexico to avoid an 8-15 year prison sentence he gained from trying to kill Ian's sister, Sammi Slott (Emily Bergyl). Ian, however, chose to move on with his life.

In an interview with The Chicago Tribune, though Fisher said Mickey was his favorite character to play, he chose to leave the show on his own accord, explaining that he felt Ian and Mickey's "beautiful journey" had come to an end, as they both found their way to accepting pivotal issues, including Ian's mental health and Mickey's sexuality. "I think that's this really lovely story," Fisher explained. "And very powerful and moving. And for me, I thought that was a fairly complete story, if that makes sense. So I thought it was relatively complete and wanted to do some journeying." He went on to star in other projects during his hiatus, but eventually returned to the show with Monaghan during its final seasons. Fans were happy to see them return and get married in Season 10.

As much as we'd hate to admit it, few shows can survive without their anchor characters. In the case of "Shameless," the anchors were Macy and Rossum. Rossum, especially, was the leader of the Gallagher pack, both behind and in-front of the camera. In addition to playing the eldest daughter and the family matriarch Fiona, Rossum, who grew up as an only child, has said she seamlessly took on the "big sister" role with her younger co-stars in real life. It seemed as if she would remain on the show until it reached its final episode and had served as a director. So, many viewers were shocked when Rossum confirmed in a Facebook post that she was stepping away from her longtime role at the end of Season 9. "The opportunity to play Fiona has been a gift," she wrote in August 2018. "There are few characters — female or otherwise — as layered and dynamic. She is a mother lion, fierce, flawed and sexually liberated. She is injured, vulnerable, but will never give up."

Rossum's absence came just one year after she publicly demanded to be paid equally to Macy. The demand delayed shooting for the show's eighth season. While she received the pay she asked for, she moved forward with ending her time as Fiona, marking a significant void in the Gallagher household. Rossum went on to work on other projects, including starring and executive producing Peacock's "Angelyne." 

While none of the Gallagher siblings will admit to being perfect, Carl Gallagher's story arc is incredibly shameless. Played by Cutkosky, Carl stood out early on due to his affinity for setting household items on fire and mutilating toys. As his character matured, he dabbled in the Gallagher family business: crime. His "white boy Carl" days became a legendary moment in "Shameless" history, as he went from selling drugs to operating an illegal gun-carrying business at school. However, fans nearly missed Carl's wannabe gangster era. In 2014, during the show's fourth season, Cutkoksky took a break from "Shameless" for a personal yet relatable reason. 

According to The Chicago Tribune, his reason for leaving the show was due to his need for a normal high school experience. The St. Charles, Ill. native had previously attended set school while filming "Shameless" in Los Angeles, Calif., but Cutkosky chose to leave Hollywood behind to start high school with his classmates at St. Charles East High School. On the show, Carl enrolled in military school during Season 7 to keep him out of trouble. While Cutkosky eventually played Carl until the series finale, he didn't regret taking a step back. "I don't see myself as an actor," he said. "I see myself as someone who goes to work and then comes back and hangs out with his friends. ... I still want to come home and be that regular kid." 

While "Shameless" was already an established show in the U.K. years before its premiere, the U.S. version of the comedic series gained fans' attention due to the stars attached. One of the early recurring characters the show added to the fold was Oscar-nominated actress Joan Cusack. For the first four seasons of "Shameless," Cusack played Sheila Jackson. Sheila was a hilarious addition to the fictional Southside community, as she wooed Frank with a free room and board and practiced her bedroom fetishes on him. She also bravely faced a battle with agoraphobia during the show's early seasons, adding representation to the very real clinical disorder.

Though Cusack wasn't a main cast member, her role as Sheila was one fans didn't think they would have to abruptly say goodbye to. Alas, after four seasons and 44 episodes, she left the series in 2015. Cusack's departure was reportedly a personal one, as she wanted to focus on finishing raising her youngest son, Miles Burke, with whom she shares with her husband, Richard Burke. While discussing her exit at a 2017 panel at Salt Lake Comic Con, she hinted that she had to consider how her role as Sheila affected her son, who was still in high school when she was on the show. Cusack teased she could return to the show after her son graduated, and reportedly planned on coming back for the final season, but couldn't due to COVID-19 restrictions.

Lip Gallagher was known for a few things on "Shameless": his intelligence, his anger issues, and his ability to find himself in hopeless relationships. We first witnessed his mostly tragic track record with love in Season 1, with his first recurring love interest, Karen Jackson (Laura Slade Wiggins). Karen and Lip's friends-with-benefits storyline was exhilarating to watch, as their struggle to choose one another resulted in the character's heartbreaking ending. In Season 3, Wiggins was removed from "Shameless" after her character suffered a frontal lobe brain injury after getting hit by a car by Lip's other love interest, Mandy (Emma Greenwell). Her story ended with her moving to Arizona with her husband, Jody (Zach McGowan), and her son, Hymie (Joanna Lee). 

Following her final episode, Wiggins implied that her character's arc ended due to the writers changing up the show's trajectory. In a previously aired interview after her exit, she shared that Karen was written off the show to give the writers more room to focus on the Gallagher family, which is plausible since Cusack, who played her mother, made her exit soon after. However, while reflecting on her time on "Shameless," Wiggins said she felt her early departure was a good thing due the pressure she felt to "look the part" in nude scenes. "The nudity definitely puts you in a space where you're really worried about what you're eating," she explained in an interview with Parade.

"Shameless" fans witnessed the show's eccentric nature from the opening of its pilot episode. The series opens with Frank introducing his family, including a few positive words about each of his six children. Once the camera pans to Liam, a Black, light-skinned toddler, Frank, who is white, says his youngest son looks just like him, opening with the evolving suspicion that Liam might not be Frank's biological child. Eventually, a paternity test proves that he's actually a Gallagher after all. In the show's early seasons, the character was Fiona's most dependent sibling, as he was only a toddler at the time. Liam's story further developed, as he played a pivotal role in Fiona's story. An unforgettable moment between them came when he had an accidental overdose after getting into his older sister's cocaine during Season 4, resulting in her arrest and catastrophic downfall throughout the rest of the season. 

Liam was originally played by twins Brennan Kane and Blake Alexander Johnson. The twins played the character until the end of Season 2, after which the casting directors recast Liam with another set of twins, Brenden and Brandon Sims. The Sims twins seemingly worked for a while, but, as the character matured, so did his storylines. By Season 8, the showrunners reportedly wanted more visibility and edgier storylines for Liam, which forced them to recast the role once again. Christian Isaiah ultimately took over the role during its final three seasons. 

After Levy left "Shameless" after one season, her character, Mandy Milkovich, lived on through actress Emma Greenwell. Before "Shameless," Greenwell had landed guest roles on other popular television shows, including "True Blood," "Holy Ghost People," and "Law & Order: Special Victims Unit." However, her time playing Mandy gave the character a darker edge, as she did whatever she could to stay in her love interest Lip's orbit. Her loyalty ranged from adorable yet ethically questionable gestures, such as plagiarizing famous speeches for his college admissions essays, to the more illegal acts of love, including running his other girlfriend, Karen, over with her car, causing her traumatic brain injury. Mandy's growing affection for Lip continued until the character vanished from the series in Season 6. In her final episode, she revealed to Ian that she found a job as an escort and had reached out to him to help her remove a client's dead body. 

In a 2016 interview with Interview Magazine, Greenwell explained that she was ready to move on from the show she had worked on for four years. She even said she wanted a more tragic ending for her character, but the showrunners wouldn't go for it. "I would love to be killed," Greenwell joked to the outlet. "I'm like, 'Come on, kill me. Are you killing me?' They're like, 'Maybe next season.'" She went on to star in several projects after leaving "Shameless," including 2016's "Pride + Prejudice + Zombies."

While "Shameless" is based around the loyalty the Gallaghers share for one another, in many cases, everyone else in their lives is collateral damage. During Seasons 3 and 4, actor Jake McDorman's character, Mike Pratt, was one of the few stable people to enter the family's life. On the show, McDorman played Fiona's boss and eventual boyfriend. From the beginning, Mike offered Fiona a relationship she hadn't experienced before, one filled with consistency and chivalry, something we hadn't seen from her ex, Jimmy/Steve. Alas, Mike's sweetness proved not to be what Fiona was looking for, as she cheated on him with his brother, Robbie (Nick Gehlfuss). The act cost her a boyfriend and her job, and was the catalyst to her eventual downward spiral at Season 4's end.

Mike and Fiona's story ended after he bailed her out of jail after she was arrested for Liam ingesting the cocaine Robbie gifted her. From there, we never see Mike again, ending McDorman's character arc. The decision didn't appear to be his, as his character's story fizzled out when Fiona moved forward without him. Ahead of his time on the show ending, McDorman said in an interview that, while he and Rossum had chemistry during his audition for the role, he was aware that not all of the "Shameless" characters are supposed to last forever, and took his exit in stride. He went on to work on other projects, including "Dopesick" and "Night Always Comes."
