Although "North by Northwest" may pay homage to popular culture, the film's understanding of moral relativism and conspiracy during the Cold War is not shallow. "North by Northwest" has a good understanding of moral relativism and conspiracy during the Cold War. The film adopts layers of advancement to replace suspense, and adds a lot of humorous dialogue to enhance the characterization of the characters. With another approach, the suspense of the paragraphs with increasing levels and full of motifs transcends the overall suspense. In the small and exciting passages, Hitchcock demonstrated his outstanding handling of details. The passage of being chased by a small plane and escaping into the cornfield has become all the classic passages that Hitchcock must quote. Yugoslav director Custorica used one in the "Arizona Dream" filmed in the United States. The identity of a movie fan allows his actors to imitate this passage for a large part. In addition, the escapes at the auction, the empty bag bombs to obtain letters, and the various wits in Weidan's residence, although they have been imitated many times by later generations, they still feel the original and wonderful. However, compared with Hitchcock's other works, this most prestigious work appears to be less rigorous in structure because of too much attention to detail, and even in some places the story is slightly far-fetched, which is a flaw in the beauty.
Hitchcock has a keen sense of humor and can always catch the audience's attention by accident. With strong styles such as fear, suspense, and black humor, the film shows Hitchcock’s amazing talent and is also the most entertaining one of Hitchcock’s movies
