If you loved Kingsman: The Secret Service, try Argylle
A bridge between a film you've already seen and one most people haven't. Argylle has roughly 10.3× fewer votes than Kingsman: The Secret Service — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Matthew Vaughn, and they both carry the playful mood tag, and they sit in Action / Adventure / Comedy territory. If that's the register that drew you to Kingsman: The Secret Service, the second film will land in a comparable space — through a different lens.
What Argylle is
London, rainy nights, a typewriter clacking. A reclusive author's fictional spy plots mirror real-life covert actions, cat by her side, as a cat-allergic spy joins her on the run. Vaughn brings his Kingsman energy to this globe-trotting adventure.
