Even ensemble shows tend to rest on the back of one or two core characters. Without its lead, the series wouldn’t be the same.
Sometimes, however, the lead actor decides to walk away from the show, or the studio decides to cut them loose. Then, it’s up to the showrunners to figure out how to move forward with the series (if it doesn’t end up being canceled).
Here are 18 TV shows that wrote off the main character but kept going:

Somers wanted to renegotiate her contract ahead of Season 5 for a raise — she allegedly made $30k per episode, while John Ritter allegedly made $50k. The network only agreed to a $5,000 per episode raise, and when Somers didn't accept they limited her appearances in Season 5 to 60 seconds per episode.

Topher Grace played Eric Forman on "That '70s Show" for seven seasons, but landing roles in movies like "Ocean's Eleven," "Traffic," and "Win a Date with Tad Hamilton!" inspired him to leave.

The show only lasted for one more season after Grace's departure. However, he returned for the series finale. He's also set to reprise his role in the spin-off "That '90s Show."

24
The show was reworked into the spin-off "So Random," which made the fictional sketch comedy show from the original series a reality. Sonny was replaced by her former nemesis/love interest Chad Dylan Cooper (played by Sterling Knight), but the show never addressed why.

You came and you sat next to me. You started off by just joking. You were like, 'What's going on?' I was like, 'I don't know what to do,' and you said, 'Run!'"
35
She continued, "You said, 'There are so many chapters in life and this is just one.' You were the only person that gave me permission to go. I so valued your opinion of me and of our business, and the way you prioritized your family over work. That's what I wanted."

She told E! News, "Halfway through Season 2 I would say, when we started doubling up on episodes and shooting [became] so much harder...I just didn't feel I could keep going."
39
Production gave her a choice — "Do you want your job and to sail off into the sunset and potentially you can come back in the future in some bizarre TV scenario, or we can kill your character off and you can go on with your career that you want and what you want to do?"
