Three Days of the Condor (1975)
Addison Powell: Atwood
Joe Turner : What does Operations care about a bunch of damn books? A book in Dutch. A book out of Venezuela. Mystery stories in Arabic.
Atwood : Wait!
Joe Turner : What the hell is so important about...
[He stops as he sees the connection]
Joe Turner : Oil fields. Oil. That's it, isn't it? This whole damn thing was about oil! Wasn't it? Wasn't it?
Atwood : Yes, it was.
