Olivia Cooke Makes a Surprise Return in the Trailer for Slow Horses Season 6
The first trailer for Slow Horses Season 6 confirms that Olivia Cooke and Rosalind Eleazar are back.
Apple TV has unveiled the first trailer for Season 6 of the spy series Slow Horses, sparking excitement among fans as it features the unexpected return of Sidonie Baker, portrayed by House of the Dragon's Olivia Cooke. Cooke briefly graced the show's premiere in April 2022, but her exit left a dramatic mark. Her character's storyline remained unresolved, prompting fans to eagerly anticipate her return throughout each subsequent season, even referencing it in Mick Herron's Slough House novels.
The trailer's opening sees Gary Oldman's Jackson Lamb and Kristin Scott Thomas's Diana Taverner engaging in conversation, while the series' antagonists plot against Slough House, a home for MI6 spies. New additions to the cast include Rosalind Eleazar as Louisa Guy, who announced her departure from espionage in Season 5, and Hugo Weaving as Frank Harkness, River Cartwright's (Jack Lowden) menacing father.
The trailer hints at more confrontations, including a potential showdown between River and his father. Slow Horses has maintained a yearly schedule, except for Season 2's delayed release. Season 6 will adapt two books from Herron's series, whereas the typical format features one. Season 7 has already been commissioned, with the first episode dropping on September 16, with additional episodes releasing weekly.
