“The word that comes to mind for me is ‘natural.’ I hope people, when they see this season, will feel that it has a natural shape to it,” Armstrong said on the red carpet at the Season 4 premiere, on March 20 at New York’s Jazz at Lincoln Center.

“That’s how I pitched it to my writers’ room, kind of hoping I’d get argued out of it so we’d see a way to do more seasons, because I love working with these people. There’s feeling of completeness and rightness to the shape of the show.”

Favorite Series Finales

Armstrong “loves” the ending of “Six Feet Under” and the “controversial” farewell of “The Sopranos,” though he said he wasn’t directly inspired by the final episodes of his HBO predecessors.

“Each show is different. ‘Six Feet Under,’ ‘Sopranos,’ some of the shows I most admire have radically different conclusions,” it’s got to feel right for that story. I’m inspired by those shows, but the ending of ‘Succession’ had to be bespoke, obviously.”

At the end of Season 3, Logan (Brian Cox) threw expletive-laden wrench in his kids’ plan to stop Waystar Royco’s merger with GoJo with the help of his ex-wife Caroline (Harriet Walter) and Tom (Matthew Macfadyen), who sold out his own wife, Shiv (Sarah Snook), in order to fortify his post in the new administration.

Hinting at where we find Tom and Shiv in Season 4, Macfadyen said, “They’re in a dark place. They haven’t spoken about what happened in Season 3, the betrayal in Italy. They’re sort of having a trial separation.”

While, in the Season 3 finale, Tom cashes in on years of emotional and professional torment with shocking ploy for power, Macfadyen believes Tom’s motives are mostly wholesome: “He just likes to be liked. He wants to be happy in his marriage. He wants his father-in-law to approve of him. He wants Greg [Nicholas Braun] close so he can bully him.”

At their fourth and final premiere party, the cast and crew recalled their last days of shooting.

J. Smith Cameron reflected, “It was terrible. It was a lot of people bawling our eyes out. I might start crying tonight. It’s very, very hard to say goodbye to ‘Succession.’”
