Olivia Cooke Says ‘Slow Horses’ Season 8 Could Be Its “Last,” But “Never Say Never”

As Slow Horses saddles up for Season 8, Olivia Cooke recently teased that it could be a final lap around the track.

The actress, who recently reprised her role as Sid Baker for Season 6, confirmed that she will be back for the newly announced eighth season of the Apple TV+ spy thriller from creator Will Smith and based on Mick Herron’s Slough House novels.

“I am shooting the last season!” she told The Times, before clarifying “never say never” about the fate of the series. Deadline has reached out to Apple, but no official renewal decision beyond Season 8 has been announced.

Cooke added, “But I think that’s what we’ve been told and it definitely feels like we are ending. We’re all melancholy, distracted. Yesterday, I got in the make-up chair and cried. The show’s been a shining light and I’ve told my partner I need two weeks to get over it. I’m going to be depressed.”

Following her three-episode arc as MI5 agent Sidonie “Sid” Baker in the first season, during which the character was seemingly killed off, Cooke noted that she wasn’t surprised to be asked back for Season 6 because the show kept “checking my availability over the years.”

“And we stayed in touch,” explained Cooke “It was like I’d never left.”

In September, a day before the Season 6 premiere of Slow Horses, which had already been renewed early for a seventh season, Apple gave the series an early Season 8 renewal as well. The eighth season will be based on the Herron novel Clown Town, the ninth in his Slough House books.

Slow Horses follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House. Gary Oldman stars as Jackson Lamb, the brilliant but cantankerous leader of the spies, who end up in Slough House due to their career-ending mistakes as they frequently find themselves blundering around the smoke and mirrors of the espionage world.
