However, most people will know that her big break came when she appeared in Grey’s Anatomy and became one of the rising stars of the TV industry. After that, she landed a leading role in a comedy film called Knocked Up. However, her growing interest in the big screen did not go well with the shooting schedule of the medical drama. In the end, she decided to leave the show thanks to creative differences.
Jerry Seinfeld
Seinfeld was a sitcom that starred and was created by Jerry Seinfeld. During its run of nine seasons, the ratings remained sky-high. This was the reason fans had been so confused when it came to an end. It turned out that the show ended since Jerry Seinfeld no longer wanted to do it. Reports claim that he decided to pull the plug on the show during the ninth season because he has a fascination with the number nine. On top of this, he also wanted to leave while the show was still on top! He wanted to go out on a high note instead of raking in more money with yet another season and risking its quality.
