Apple TV+ continues to bulk up its slate of original dramas and coming soon is another new series with an all-star cast.


Slow Horses is based on the novel of the same name by Mick Herron, which is part of the author's Slough House series. It tells the story of a team of British intelligence agents who have all committed career-ending mistakes, and subsequently work in a dumping ground department of MI5 called Slough House.

The series is said to be "darkly funny" and stars Gary Oldman as the department's leader, Jackson Lamb, alongside a stacked cast including Olivia Cooke, Kristin Scott Thomas, Jack Lowden and Jonathan Pryce.

The six-part first season will be releasing on the streamer soon, and it seems there's potential for more from the Slough House team on the way.
