Making Cinema History
Cinematographer Gordon Willis wanted to experiment with some angles. He insisted that each shit in the film should be from the point of view of another character. So, they decided that every single shot would be filmed at the height of four feet.
What about the aerial shot?
Yes, yes, there's an aerial shot that is obviously not filmed at the height of four feet. Coppola convinced Willis to do an aerial shot by saying that it was the "point of view of God." That's fair!
