Hitchcock liked assembly lines. In the long, consistently revealing interview he gave to François Truffaut in the summer of 1962, he described a scene he had thought of including in North by Northwest (1959), but didn’t. Roger O. Thornhill (Cary Grant) is on his way from New York to Chicago. Why not have him stop off at Detroit, then still in its Motor City heyday?
I wanted to have a long dialogue scene between Cary Grant and one of the factory workers as they walk along the assembly line. They might, for instance, be talking about one of the foremen. Behind them a car is being assembled, piece by piece. Finally, the car they’ve seen being put together from a simple nut and bolt is complete, with gas and oil, and all ready to drive off the line. The two men look at it and say, ‘Isn’t it wonderful!’ Then they open the door to the car and out drops a corpse!
