Key Points:
- The creative team behind Apple TV’s Slow Horses anticipated fan reactions to the shocking ending of the sixth-season finale and prepared an alternate, happier ending as a backup.
- Director Adam Randall revealed that while the aired ending, featuring River Cartwright’s tragic poisoning, aligns mostly with Mick Herron’s Slough House books, a more uplifting conclusion was also filmed.
- The happier ending was intended as a potential series finale if the show had not been renewed, offering a "magical" and Spielberg-like conclusion to River’s story.
- Ultimately, the darker ending was chosen to stay true to the source material and set up the narrative for Season 7, despite the season's overall grim tone.
- The show was renewed for two more seasons in July and September, allowing the story to continue beyond Season 6.
