'Succession' star Brian Cox says Sarah Snook was the last person to find out the show was ending: 'We all thought everybody else knew'

• "Succession" star Brian Cox said Sarah Snook only found out the show was ending at a table read.
• The Scottish actor said: "We all thought everybody else knew."

The story of the Roy family and Waystar RoyCo is coming to a close with "Succession" season four, and it's anyone's guess as to which of the Roy siblings will succeed their father, Logan Roy (Brian Cox), as head of the company.

The series has raked in rave reviews over its past three seasons, earning itself a 95% critics' score on Rotten Tomatoes, so it's interesting that creator Jesse Armstrong is choosing to end it with season four rather than carrying on for a few more years.

It seems like something the whole cast would've been told before starting work on the new season, but during an appearance on Saturday's episode of the UK talk show, "The Jonathan Ross Show," Brian Cox said that Sarah Snook was the last person to know the show was ending.

In fact, the actor behind Shiv Roy only found out what was happening at the table read for the final episode.

He explained: "She only found out it was finishing at the table read of the last episode, which is a bit late. We all knew. We all thought everybody else knew. I knew for a while."

Snook recently opened up about learning the show was ending at the table read, telling The Los Angeles Times that she was "upset" when she learned it was finishing.

She said: "I was very upset. I felt a huge sense of loss, disappointment, and sadness. It would have been nice to know at the beginning of the season, but I also understand not being told until the end because there was still a potential that maybe this wasn't going to be the end."

The star went on to call the decision "smart" so that the show doesn't go on forever and lose what made it great.

She added: "Emotionally, all of us weren't necessarily ready to be done with the show because we love each other so much. But everything has to come to an end, and it's smart not to let something become a parody of itself."

Cox also told Jonathan Ross that he's fine with "Succession" ending with season four, but he's going to miss the cast and crew involved with making it.

He said: "There's been a remarkable closeness with all of us. I don't really mind the show ending, but it's the people, the folk. The crew, the wonderful camera operators… It's the whole shebang. The whole lot. It's the best thrill in the world, sad when it's over."
