Slow Horses Season 5: What time and date is episode 1 out? Release schedule, cast and how to watch


Jack Lowden and Gary Oldman are back as the spies who just can’t catch a break.
Fresh from winning the Emmy for ‘Outstanding Directing for a Drama’ for its fourth season, Slow Horses is about to return to television screens for its fifth outing.
Based on the Slough House series of novels by Mick Heron, the show follows the adventures of a group of failed special agents who have been put under the supervision of Jackson Lamb, played by Gary Oldham.
It also stars Scottish actor Jack Lowden as River Cartwright, who was a hotly tipped agent before a training-exercise blunder sent him to the purgatory of Slough House. He very much sees himself as a James Bond figure - with Lowden ironically in the running to play the world’s most famous spy in the next big screen outing.
The show has been a huge success, with season four earning a rare 100 per cent critical rating on Rotten Tomatoes.
