North By North-West; Hitchcock 1958

The "Crop Duster" scene

This particular scene in North By North-West features the main character of Thornhill being sent to meet a man who will explain why he has been mistaken for a goverment agent and, we beleive, help him. There are large amounts of tension created during this scene, this is made through a lack of noise, and through a number of 'unsuccessful' tension build ups (such as when he is waiting by the road for a car, but several pass by without notice).
