I’m sure they’d most like to point to Goldfinger and say “Yep, that’s us, that’s what we do!” But does anyone happen to know if there’s a spy movie that CIA agents pretty much agree is the most authentic/realistic of the genre?
I’ve heard that, among terrorists, Black Sunday is a big favorite, at least in book form.
They’d tell you, only they’d have to kill you, afterwards. 
Is anyone going to admit to being a spy in order to answer this?
I’d settle for someone having a crusty old CIA father-in-law who might have mentioned something about it. I actually grew up in a neighborhood where about half the families on my street had a CIA parent, but didn’t know it until my high school 20-year reunion…
What about The Good Shepard? Terrible movie by the way. A little too realistic.
I wonder if their answer would be “Meet the Parents.”
Let me call my cousin, the retired Army Counter-Intelligence officer and ask him. I’ll get back to you.
I would say Graham Greene’s novels would be rather trustworthy (and all together brilliant). Movie adaptation I don’t know much about, but wasn’t there a Michael Caine movie recently…?
How about Breach? Supposedly the movie was very accurate to the real life story (although there were a few changes made), and I loved Chris Cooper’s performance as Robert Hanssen.
Back in the days of dinosaurs and the cold war, a movie called “The Spy Who Came in From the Cold” was highly thought of.
Spy Game, with Robert Redford and Brad Pitt?
Well it’s not quite the genre you’re looking for but my old grad school officemate was the son of a guy who ran the executive protection branch of the Secret Service for a while and he said that the movie which got most of the feeling of that job right was “In The Line Of Fire”.
When I lived in Laurel, MD many of my neighbors “worked for DoD”. The one movie I remember being favorably talked about was In the Company of Spies.
