Apple TV’s six-part mini-series Slow Horses, adapted from the novels of the same name by Mick Herron, landed on 1 April with a one-two punch and promptly kept viewers waiting, having decided to parse out the remaining four episodes out on a weekly basis. “It was Apple’s decision,” says director James Hawes. “But if the response I’ve had is anything to go by, the anticipation it has created is fantastic. I’ve got people ringing me up to say, ‘Why are you doing this? I wanted to finish it over the weekend!’ The greatest compliment you could have is that people are demanding more—and now.”
