Slow Horses (Seasons 1–5)

Slow Horses (2022) is an Apple TV+ spy thriller you can watch online on iFILM. Based on Mick Herron's acclaimed novel series, it follows Jackson Lamb — a brilliant but deeply unpleasant MI5 veteran played by Gary Oldman — who runs Slough House, a dumping ground for agents who've made career-ending mistakes.

The "slow horses" under Lamb's roof include a man who lost a surveillance target, a analyst who sent classified files to the wrong address, and others whose files are too awkward to simply close. They handle dead-end paperwork. Until a case lands that turns out to be anything but routine. Jack Lowden, Kristin Scott Thomas, and Jonathan Pryce round out a cast that keeps the tone sharp — equal parts dry wit and genuine menace.

The series launched in 2022 and built a loyal following fast, praised for its wit, moral complexity, and a Gary Oldman performance that earned widespread critical attention. Stream all seasons of Slow Horses online on iFILM.
