Apple TV+ has announced a new, six-episode sixth season for See-Saw’s spy drama Slow Horses following its season four finale.

Season six will see the Slow Horses on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge.

The Emmy and BAFTA Award-winning series stars Academy Award winner Gary Oldman who will return as Jackson Lamb.

“Audiences around the world have fallen in love with the Slow Horses, and I’m delighted that Gary Oldman will be leading this star-studded cast on another acerbic and action-packed adventure,” said Jay Hunt, creative director, Europe, Apple TV+.

The series is produced for Apple TV+ by See-Saw Films, with Jamie Laurenson, Hakan Kousetta, Julian Stevens, Iain Canning, Emile Sherman, Adam Randall, Gail Mutrux, Douglas Urbanski and Gary Oldman serving as executive producers. Season six is adapted for television by co-executive producer Gaby Chiappe, with Adam Randall returning to direct.

The complete first four seasons of “Slow Horses” are now streaming on Apple TV+, and season five was announced earlier this year.
