Sarah Snook was "very upset" to learn about Succession ending at a table read
Sarah Snook felt "a huge sense of loss, disappointment and sadness" upon realizing that Jesse Armstrong's HBO favorite would conclude with season 4

Succession creator Jesse Armstrong’s confirmation last month that the HBO favorite’s highly-anticipated fourth season would be “pretty definitively the end” came as a shock to the system for the drama’s dedicated fanbase. As it turns out, they’re not alone: Sarah Snook, who stars on the series as beige-loving girlboss Siobhan Roy, says that she didn’t have an inkling that the series was concluding until she sat down at a table read.
“I was very upset,” she shares with The Los Angeles Times’ Meredith Blake. “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.”
