Here’s some simple TV math: the longer a series airs, the less likely its original cast will remain intact, regardless of how beloved the show or actor is. The majority of popular series over the years have gone through at least one major exit, and it’s bad enough when changes are revealed early, and characters’ last episodes are planned out and logical. It's far worse, however, when actors suddenly exit projects without any on-screen closure.
Surprise departures can curb audiences' enjoyment of a show, whether from disrupted cast dynamics or shoddy storytelling. And depending on how controversial the exits are, a key departure can completely derail a show's success. So let’s take a look back at some of the most memorable instances when stars parted ways with projects without closing their characters' stories.
Anna Faris (Mom)
During Mom's hiatus following Season 7, co-star Anna Faris suddenly revealed she was leaving the show, which reportedly shocked the creative team as much as fans. Allison Janney & Co. went forward with the eighth season, occasionally referencing Faris’ character Christy, but it was canceled without any kind of conclusion for the character, though the creators made it clear they didn’t want to kill her off.
Chevy Chase (Community)
Community already suffered the exodus of creator Dan Harmon and more creatives in Season 4, and then Chevy Chase allegedly used a racial slur on the set, leading him to drop out of the NBC comedy through mutual agreement with network execs. His character Pierce appeared multiple times after his official exit, due to episodes airing out of order, as well as that hologram cameo in the Season 5 premiere, but the SNL vet never returned as a regular, and was unceremoniously killed off via dialogue two episodes after the cameo.
Danny Masterson (The Ranch)
That ‘70s Show vet Danny Masterson reteamed with Ashton Kutcher on Netflix’s sitcom The Ranch, but was fired in December 2017 after multiple assault allegations against him were publicized. Masterson later faced trial, was convicted and sentenced to prison in September 2023, and did not return as Rooster Bennett, who was written as missing and presumed dead via motorcycle accident.
Suzanne Somers (Three's Company)
Three’s Company's early seasons were bolstered by the popularity of Suzanne Somers’ Chrissy Snow, but network execs reportedly refused the actress’ salary increase requests, leading to a unique stalemate agreement. Somers made only contractually obligated appearances in Season 4 episodes' closing tag scenes, which she filmed separately from her co-stars. Somers was fired by the season’s end, with Chrissy said to be caring for her sick mom in Fresno.
Corey Hawkins (The Walking Dead)
Corey Hawkins joined The Walking Dead Season 6 as comic book fan-favorite Heath, but Straight Outta Compton's release that same year shot him to Hollywood’s stratosphere. In one of TWD’s most baffling moments, Heath disappeared in Season 7, and was never seen from again. Reportedly, Heath would have returned for the movies, but those plans have been shut down.
Emmy Rossum (Shameless)
The final two years of Shameless' 11-season run were without Emmy Rossum’s Fiona Gallagher. The actress announced her shocking exit in 2018, and Fiona’s final appearance came in the emotional Season 9 finale. Despite fans’ hopes, Rossum opted not to return for cameos in the remaining seasons, and the series finale wrapped without any major Fiona updates.
Mandy Patinkin (Criminal Minds)
Criminal Minds began its lengthy run with Mandy Patinkin’s Jason Gideon running the BAU, but that changed ahead of the third season when Patinkin left the show entirely over his disgust with the violent storylines. (He called joining the crime drama his “biggest public mistake” in 2012.) Gideon was replaced and killed off-screen seven seasons later, with Ben Savage guest-starring as young Gideon in flashbacks.
Columbus Short (Scandal)
Ahead of Scandal's Season 3 finale, co-star Columbus Short was arrested over a physical altercation at an L.A. restaurant, and eventually confessed he’d developed drinking and drug habits while dealing with a divorce and custody disputes. Short was fired from Scandal in April 2014, and his character Harrison Wright was revealed in Season 4 to have been killed off.
Gina Carano (The Mandalorian)
Former MMA badass Gina Carano landed the role of Star Wars merc Cara Dune in The Mandalorian, but lost the gig in February 2021. Following a series of controversial social media moves, Lucasfilm announced she would no longer be involved in the show. Cara Dune was not recast, and has not returned to the franchise since the Season 2 finale.
Valerie Harper (Valerie)
The Hogan Family began its existence as Valerie, starring the Emmy-winning Valerie Harper as its lead matriarch for two seasons. She was later fired after salary disputes and sued NBC and production company Lorimar. While her initial claims were dismissed, a judge ruled Harper was indeed wrongfully terminated, netting her a financial win. Her character suffered an offscreen death, leading to the series' name changes.
Robert Downey Jr. (Ally McBeal)
Following a string of 1990s scandals, Robert Downey Jr. landed the role of love interest Larry Paul in Season 4 of Fox’s hit dramedy Ally McBeal, which earned him a Golden Globe. But additional arrests in late 2000 and 2001 led creator David E. Kelley to cut ties with RDJ completely. The fifth season, which would have chronicled Ally and Larry’s post-wedding bliss, had to be completely rewritten.
Shannen Doherty (Charmed)
Though Charmed’s eldest sister Prue Halliwell was the trio's most powerful, the third season finale left Shannen Doherty’s character facing possible death. Though presumptions held that she’d return for Season 4, tensions and more issues surrounding Doherty and Alyssa Milano led to Doherty’s firing via phone call. As such, Prue’s wounds turned out to be fatal, but Doherty did not return for the funeral episode.
Clayne Crawford (Lethal Weapon)
Fox’s iteration of Lethal Weapon paired Rectify vet Clayne Crawford with Damon Wayans. But instead of buddy cop love, reports indicated strife and hostility building between the co-stars, along with complaints about Crawford's directorial work. His exit was reported on the day of the Season 2 finale, which ended on a cliffhanger for his character Riggs, who was unsurprisingly revealed to have succumbed to his wounds. Seann William Scott joined Season 3 as a replacement.
Grace Park (Hawaii Five-0)
After seven seasons portraying Kono Kalakaua for CBS’ Hawaii Five-0 reboot, Grace Park opted to vacate her role alongside Daniel Dae Kim after their attempts to secure pay equality with co-stars Alex O’Loughlin and Scott Caan were turned down by CBS Television Studios. Kono was revealed to have relocated to Carson City, Nevada, as part of a trafficking task force, with Danny sharing their break-up update in Season 9.
Thomas Gibson (Criminal Minds)
Various Criminal Minds stars exited the drama for different reasons, but Thomas Gibson’s case. stands out. Despite the show still being early into filming Season 12, ABC Studios and CBS Studios revealed the actor’s termination via a joint statement in August 2016, less than a week after Gibson was suspended over an on-set altercation with a writer-producer. A later episode revealed his character Aaron “Hotch” Hotchner entered Witness Protection after discovering serial killer Peter Lewis stalking his son Jack.
Roseanne Barr (Roseanne)
One of the '90s' biggest sitcoms returned to ABC in 2018, with Roseanne bringing comedian Roseanne Barr back as its matriarch. But that return only lasted for a single season, as Barr tweeted a message about former White House Advisor Valerie Jarrett that was considered racist, and two months after its Season 11 renewal, Roseanne was effectively canceled. The network relaunched without Barr as The Conners, which kicked off its run by killing off Roseanne Conner via drug overdose.
Charlie Sheen (Two And A Half Men)
Two and a Half Men thrived on the chemistry between Charlie Sheen and Jon Cryer, but the show went into hiatus in 2011 due to Sheen’s then-latest rehab stint, at which point the actor began slamming CBS and Chuck Lorre in a variety of high-profile interviews. Season 8 was then shut down mid-production, with Sheen’s firing later capping things off. His public meltdowns continued capturing headlines as Ashton Kutcher helped fill the Charlie void, and unfortunately didn't make good on rumors of his series finale return.
Lisa Edelstein (House)
Across her years as Dr. Lisa Cuddy, House star Lisa Edelstein went from playing contentious boss to adoring lover. Upon Season 7’s end, she and two co-stars were asked to take salary cuts during contract negotiations, with Edelstein being the lone holdout. She announced her exit ahead of Season 8, and Cuddy was later revealed to have quit as Dean of Medicine, with Omar Epps’ Eric Foreman taking on the duties for the final season.
James Garner (Maverick)
For three seasons, James Garner portrayed Maverick's title character Bret Maverick, but the 1960 writers' strike helped bring that run to a sudden close. When Warner Bros. attempted to lay Garner off due to a lack of scripts, he fought back and successfully sued the studio for breach of contract. According to the actor, he personally turned down an offer to return with a raise, saying, “I want out,” and though Bret appeared in an airing-delayed Season 4 ep which was filmed far earlier, Garner did not return, with fill-in stars Roger Moore and Robert Colbert added later.
Katherine Heigl (Grey's Anatomy)
Katherine Heigl took a temporary leave from Grey’s Anatomy in Season 6 to shoot a movie and spend time with her adopted daughter, which sparked her to request to be released from her contract 18 months early. Disputes have raged on over how her sudden exit was handled, considering Izzy never experienced an official “farewell” scene. Alex Karev’s final ep specifically noted that he and Izzy were back together and raising twins in Kansas. While Heigl notably reunited with former co-stars at the Emmys, giving fans hope that Izzy could return, she has yet to justify those hopes.
Jeff Garlin (The Goldbergs)
Nine months after The Goldbergs co-star George Segal died at 87, lead actor Jeff Garlin vacated the show following multiple HR investigations into allegations of misconduct. The departure was said to be a mutual agreement between the actor and the producers and network, and because it happened in the middle of filming Season 9, the producers used CGI, physical stand-ins, and archival audio to make it appear as if Murray was still around. The writers ditched that idea going into Season 10, though, and revealed Murray's off-camera death.
Freema Agyeman (New Amsterdam)
Freema Agyeman portrayed New Amsterdam's oncology chief Dr. Helen Sharpe for four seasons, and while many expected her back for the fifth and final season, the actress shockingly announced her exit amid the summer hiatus, cheekily pleading for fans to continue Sharpe’s story via fan-fiction. She went on to co-star in the series Dreamland, cementing Sharpe and Dr. Goodwin’s break-up, and though the character did appear on TV in a later Season 5 episode, it was without any overarching updates.
Hartley Sawyer (The Flash)
In 2017, actor Hartley Sawyer landed his stretchiest role yet as The Flash’s Ralph Dibny, a.k.a. Elongated Man. Three years later, in response to his comments about Black Lives Matter, social media users pulled up multiple derogatory and offensive tweets the actor posted between the years of 2009-2014. He publicly apologized for the posts, but a week after waves were made, Warner Bros. TV and The CW fired Sawyer from The Flash, which used an uncredited body double for Season 7’s “Mother” to write Ralph out alongside Sue Dearbon.
Jill Marie Jones (Girlfriends)
Jill Marie Jones crushed it as Girlfriends’ ego-driven Toni Childs for six seasons but was the only main cast holdout who exited the dramedy ahead of Season 7 over her contract expiring. Jones' exit was explained through Toni moving to New York City at the end of Season 6, but Jones spoke openly in 2007 about feeling that Toni’s story wasn’t over and that she'd be willing to return if the writers put something together. Alas, the show was canceled in 2008 before that could happen.
Lori Loughlin (Fuller House)
Lori Loughlin returned to her Full House role of Rebecca for the Netflix continuation series Fuller House, but her appearances ceased in Season 4 after she was fired by Netflix over her and her husband Mossimo Giannulli’s actions regarding the 2019 college admissions bribery scandal. Though the actress was later able to reprise her When Calls the Heart character, Aunt Becky didn't return at all for Season 5.
Kevin Spacey (House Of Cards)
Alongside Robin Wright, Kevin Spacey made streaming TV normal with Netflix’s House of Cards. In the weeks ahead of Season 6's production, Spacey faced widely publicized accusations from actor Anthony Rapp, was subsequently fired by Netflix and was removed from executive producer duties. His character Frank Underwood was revealed to have been poisoned and died ahead of the Season 6 premiere.
Leanna Creel (Saved By The Bell)
Leanna Creel’s Tori Scott remains one of pop culture's biggest curiosities, having slid into NBC’s Saved by the Bell for its final season during a run of episodes lacking Tiffani Thiessen’s Kelly and Elizabeth Berkley’s Jessie. The leather-clad character shook things up for Zack & Co. for just ten episodes, and was never heard from again.
Wayne Rogers (MASH)
Three years after joining CBS' MASH, actor Wayne Rogers grew discouraged by his character Trapper John not reaching his expectations, and unexpectedly opted to quit the hit series ahead of its fourth season. But while fellow exiting co-star McLean Stevenson was able to be written out of the Season 3 finale, Trapper John's absence had to be explained away in the Season 4 premiere without Rogers around.
Ruby Rose (Batwoman)
Batwoman’s first foray into live-action saw Ruby Rose wearing Kate Kane's cape and cowl, but she left the Arrowverse series shortly after the first season ended. Reports noted she was fired over on-set behavior, with Rose claiming the show’s taxing nature led her to suffer back surgery following an alleged on-set accident. Replaced as a lead by Javicia Leslie's Ryan Wilder, Kate later returned in a different physical form without Rose’s involvement.
Kate Jackson (Charlie's Angels)
O.G. Charlie’s Angels star Kate Jackson won viewers’ hearts for three years as Sabrina Duncan, which is when she followed former co-star Farrah Fawcett out the door. Jackson spoke warily of the writers’ scripts, and after being denied the opportunity to join Kramer vs. Kramer due to scheduling, she intentionally caused an on-set mess that led to her dismissal ahead of Season 4. Replaced by Shelley Hack’s Tiffany Wells, Sabrina was revealed to have left the agency to become a mother.
Jon Seda (Chicago P.D.)
Jon Seda’s Antonio Dawson jumped from Chicago Fire to P.D. to Justice and back again for seven years. Surprisingly, NBC and Wolf Entertainment chose not to renew Seda’s contract ahead of Chicago P.D.'s seventh season, and he was let go. Later episodes revealed the character fell back into pill addiction following the prior finale's cliffhanger, and he was checked into rehab, eventually moving to Puerto Rico after resigning from the force.
Selma Blair (Anger Management)
Charlie Sheen followed Two and a Half Men with the comedy Anger Management, co-starring Selma Blair for part of its run as his colleague and fling interest Dr. Kate Wales. Conflict between Blair and Sheen bled into the tabloids, and a reported ultimatum from Sheen led producers to fire Blair, with her character suddenly being explained away as having moved to India.
