Ready for some new must-see TV? Look no further than what Apple TV+ has on deck with the latest season of its popular ‘Slow Horses’ series.

The international hit comes through with a season four trailer loaded with laughs, action and wild storytelling teasing. Giddy up and prepare for September 4.

Apple TV+ today unveiled the trailer for season four of its globally celebrated, Emmy Award-nominated and BAFTA Award-winning series, “Slow Horses,” starring Academy Award winner Gary Oldman. Adapted from “Spook Street,” the fourth novel in the CWA Gold Dagger Award-winning Mick Herron spy series "Slough House,” the six-episode fourth season of “Slow Horses” will premiere globally on Wednesday, September 4 with the first episode, followed by one new episode weekly, every Wednesday through October 9, on Apple TV+. 

“Slow Horses” is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House. Season four opens with a bombing that detonates personal secrets, rocking the already unstable foundations of Slough House. 

The espionage drama continues to receive praise and accolades heading into its fourth season. “Slow Horses” season three recently scored nine Emmy Award nominations for its widely acclaimed third season, including Outstanding Drama Series and acting nominations for Gary Oldman (Outstanding Lead Actor in a Drama Series), Jack Lowden (Outstanding Supporting Actor in a Drama Series) and Jonathan Pryce (Outstanding Guest Actor in a Drama Series). The series also earned nominations in the following categories: Outstanding Casting for a Drama Series, Outstanding Writing for a Drama Series, Outstanding Directing for a Drama Series: Saul Metzstein, Outstanding Picture Editing for a Drama Series, and Outstanding Music Composition for a Series (Original Dramatic Score). 

Oldman stars as Jackson Lamb, the brilliant but misanthropic 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. The returning ensemble cast also includes Academy Award-nominee Kristin Scott Thomas, BAFTA Scotland Award-winner Jack Lowden, Saskia Reeves, Rosalind Eleazar, Christopher Chung, Aimee-Ffion Edwards, Kadiff Kirwan and Academy Award-nominee Jonathan Pryce. SAG Winner Hugo Weaving, BAFTA winner Joanna Scanlan, IFTA winner Ruth Bradley, Tom Brooke and James Callis join “Slow Horses” in season four.

“Slow Horses" is produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith (“Veep”). Jamie Laurenson, Hakan Kousetta, Iain Canning, Emile Sherman, Jane Robertson, Julian Stevens, Douglas Urbanski, Gail Mutrux, Graham Yost and Will Smith serve as executive producers on the series. Season four is directed by Adam Randall. 

Since its premiere in 2022, “Slow Horses” has won two BAFTA Television Awards while earning nine additional nominations. The 2024 wins were for Best Editing: Fiction (Sam Williams) and Best Sound: Fiction (Sound Team), and the nominations across 2023 and 2024 included Best Drama Series, Oldman’s first for Best Lead Actor; Lowden’s for Best Supporting Actor; Best Editing: Fiction (Zsófia Tálas); Best Editing: Fiction (Katie Weiland); Best Original Music: Fiction (Daniel Pemberton and Mick Jagger); Best Sound: Fiction (Martin Jensen, Joe Beal, Duncan Price, Craig Butters, Sarah Elias and Andrew Sissons); and, Best Hair and Makeup Design (Lucy Sibbick). The series also landed the award for Best English-Language Drama Series at the 2022 C21 International Drama Awards.
