If you loved Asher, try The Jackal
A bridge between a film you've already seen and one most people haven't. 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 Michael Caton-Jones, and they sit in Action / Thriller territory. If that's the register that drew you to Asher, the second film will land in a comparable space — through a different lens.
What The Jackal is
Washington DC, autumn rain, a rifle shot. An FBI sting goes sour, a brother falls, and a psychopathic hitman is hired for vengeance. The Jackal is a villain for the post Cold War era.
