TV is most of the time very unpredictable, and the things that really matter are hardly ever shown. I mean, the biggest surprises are actually the ones that happen to the people who are waiting eagerly to find them out. Actor departures just shocked the people in a stupor, as a matter of fact, not only that, but they also changed the show’s direction, and in most cases, the storyline of the shows. Those stars, consequently, by means of these departures, were found to be involved in dirty firing, caught up in bitter personal disputes, or antagonistic fights for rights. We may as well recall the 10 greatest television episodes and the events that happened, shall we?
10. Katie Cassidy Leaves Supernatural
The third season of “Supernatural” featured Katie Cassidy as demon Ruby, which was quite surprising, but in the fourth season, Ruby was very quickly replaced by Genevieve Padalecki. The change in the cast was explained by the showrunner, Eric Kripke, as a consequence of budget cuts, but later on, Cassidy clarified that she had chosen to take another job. The fan reaction was definitely a shock to the cast, as not only did Genevieve make the character her own, but she also became the wife of the star, Jared Padalecki. To wrap it all up, she even came back for the final season of the show.
9. Maggie Roswell Walks Away from The Simpsons
Maude Flanders’ unexpected demise is still one of The Simpsons’ most jaw-dropping moments, but it was the result of a contract negotiation. Voice actress Maggie Roswell asked for a salary increase—from around $2,000 per show to $6,000. Fox offered a paltry additional $150, just enough to cover her travel expenses from Denver to LA. Roswell walked away, and Maude was struck down in the series’ 2,000th show. Viewers weren’t the only ones surprised—Springfield itself was a bit emptier.
8. Lauren Cohan Fights for Equal Pay on The Walking Dead
As Maggie Greene, Lauren Cohan was at the core of The Walking Dead. But once her contract expired, she demanded parity with the show’s male leads. When negotiations broke down, she walked away. Cohan made a return in 2020, but her previous absence was a blow to a show that was already changing. It spawned a larger debate in Hollywood—one that had nothing to do with zombies.
7. Lisa Robin Kelly’s Struggles on That ’70s Show
Lisa Robin Kelly transformed Laurie Forman into a scene-stealer on That ’70s Show, but personal struggles with addiction resulted in her being replaced after Season 3. Christina Moore temporarily took the role, and though Kelly reappeared in Season 5, her demons foiled her comeback. Her premature death in 2013 at just 43 years of age shocked fans and colleagues alike, as a cautionary reminder of how addiction can ravage even emerging talent.
6. Charlie Sheen Goes Off on Two and a Half Men
Charlie Sheen’s departure from Two and a Half Men was not simply a leaving—it was a show. Following public battles with creator Chuck Lorre and erratic appearances in the media, Sheen was let go. His character was quickly offed in an off-screen accident, and Ashton Kutcher took his place. The show struggled on, but the drama over Sheen’s breakdown became almost as well-known as the sitcom itself.
5. Mischa Barton’s Dramatic Exit on The O.C.
The death of Marissa Cooper in Season 3 was one of The O.C.’s most iconic (and heartbreaking) moments. Mischa Barton’s departure, which was portrayed as a fatal car accident, was a writer’s choice, since they saw Marissa as a cursed heroine. Although it provided the series with one of its most legendary episodes, viewers never really got over losing her—and the show was never again the same.
4. Patrick Dempsey’s Leaving Grey’s Anatomy
Derek “McDreamy” Shepherd’s death in Season 11 shattered the hearts of Grey’s Anatomy fans all over the world. But on set, there was allegedly tension. Executive producer James D. Parriott would go on to confirm that HR complaints and on-set tension were a factor in Patrick Dempsey’s exit. Though Derek appeared briefly in a dream sequence years after his death, the show had by then passed the point of no return.
3. America Ferrera Exits Superstore
As Amy Sosa, America Ferrera was the glue of Superstore. When she decided to leave after Season 5, the show lost its fulcrum. Plots flatlined, and without her to stabilize them, the chemistry of the show took a drastic turn. The show wasn’t renewed much later after she left—testimony to how important she was to its popularity.
2. Daniel Dae Kim and Grace Park Stand Up on Hawaii Five-0
After seven years, the stars of Hawaii Five-0, Daniel Dae Kim and Grace Park, decided to leave the show when CBS refused to match their pay with that of the white co-stars. Their decision sparked conversations within the industry about fair treatment and diversity.
1. Steve Carell Bids Farewell to The Office
Steve Carell’s Michael Scott was the backbone of The Office, and his Season 7 goodbye was as heartbreaking for viewers as it was for the actors. Unlike most departures on this list, Carell’s wasn’t dramatic—he had only committed to seven seasons and declined to renew. Nevertheless, his loss was keenly felt, although he did come back for a surprise cameo in the series finale. The program went on for two additional seasons, but without Michael, it was never the same. These exits, ranging from blazing firestorms to tearful farewells, did not just change the shows they belonged to— they changed the whole history of television. They remind us that, in some cases, the drama off the stage can be just as interesting as the one on the stage.
