I don’t understand how this movie is considered to be one of ‘the greatest films of all time’.

I don’t know exactly how true this statement is as I’m pulling it from Wikipedia, but that’s irrelevant because this still sums up the film’s integrity to logic: “Lehman would sometimes repeat this story himself, as in the documentary Destination Hitchcock that accompanied the 2001 DVD release of the film. In his 2000 book Which Lie Did I Tell?, screenwriter William Goldman, commenting on the film, insists that it was Lehman who created North by Northwest and that many of Hitchcock’s ideas were not used. Hitchcock had the idea of the hero being stranded in the middle of nowhere, but suggested the villains try to kill him with a tornado. Lehman responded, “but they’re trying to kill him. How are they going to work up a cyclone?” Then, as he told an interviewer; “I just can’t tell you who said what to whom, but somewhere during that afternoon, the cyclone in the sky became the crop-duster plane.”

To summarize this movie, it is a glamorous version of the  gif from the Telgu film where a man drifts underneath a train on a horse.
