That's quite the list... I think The Good Shepherd is similar thematically, even though it is more about the founding of CIA... Underrated movie, beautifully shot... Very moody

The Spy Who Came in from the Cold.

Thanks! Added to the list....

The American, with George Clooney, is good too in an old school manner of filmmak8ng.
