There are many celebrities who have become almost synonymous with the shows that thrust them to the spotlight. However, even though many fans have come to love their characters in their series, it wasn’t enough to make these stars stay.

Kourtney Kardashian – ‘Keeping Up With the Kardashians’

The Kardashian-Jenner clan’s life is well-documented via their E! reality show, ‘Keeping Up With the Kardashians,’ and fans are loving the drama that it has to offer. However, one of its cast members, Kourtney, recently revealed that she is backing out of it.

In an interview, the mom of four said that she had been on the show for 14 years already and it became unfulfilling for her. What’s more, the show turned into a toxic environment for Kourtney, who values privacy so much. In her decision, the Poosh founder explained that she would be focusing more on her kids and lifestyle brand.

Skeet Ulrich – ‘Riverdale’

In the series adaptation of the Archie comics, Skeet Ulrich played Jughead Jones’ father, F.P. Jones. He has one of the most interesting story arcs in the show, but the actor decided he will not return on the fifth season of ‘Riverdale.’

His reason? Skeet got bored ‘creatively.’ Despite the goodbye, the creator of the show said he would leave room for the possibility of the character’s return.

Jim Parsons – ‘Big Bang Theory’

Not all who watch the ‘Big Bang Theory’ understand the science the characters elucidate on but somehow, it’s a delightful thing to watch, proven by the 12 strong seasons it went live. It ended in May 2019 not because fans didn’t watch it anymore but because one of its main cast left the show.

Can you imagine what the hit show would look like without Jim Parsons’ Sheldon Cooper? It’s unclear why he bid adieu, but money may not have been the issue – after all, it was reported that he could take home $50 million in a span of two years. After he expressed his intention to depart the show, CBS announced that ‘Big Bang Theory’ would end as well.

Sandra Oh – 'Grey’s Anatomy'

After 10 long seasons, Sandra Oh announced that she was leaving the medical drama series. The actress had been onboard since day 1 as Cristina Yang, which was why the revelation shocked her fans.
