I loved that movie"Ronin" (1998). A truly sterling post Cold War action-espionage thriller from John Frankenheimer. I pretty much watch it whenever it pops up (it's free on YouTube these days).
There's a lot going on, so each successive viewing can be a novel experience, so rich is Frankenheimer's direction and detailing. Not to be overlooked is David Mamet's taut script. It's the reason the cast talks the way it does and it's great.
