Stana Katic’s Departure On Castle Led To The Worst Possible Thing

Fans of Castle were shocked when news broke that Stana Katic had been let go in April 2016. If the sources from Us Weekly are true, it may have to do with a long-feud between Katic and co-star Nathan Fillion.

She wrote about their riffs, “If I’d complained about anyone or anything, she presumed I was b******* about her…Soon, she started to ignore me, and eventually, it got to the point where she didn’t talk to me for all of Season 6.” Yikes, that’s brutal.
Betty White’s Upbeat Personality Was An Annoyance For Bea Arthur On The Golden Girls

Who didn’t love Betty White? Unfortunately, White’s upbeat personality didn’t mesh well with Bea Arthur.
In a 2013 panel discussion with the New York Times, White revealed that “Bea found me a pain in the neck sometimes because of my positive attitude.
