Fridge Logic: If you're going to lure somebody to the middle of nowhere to kill him, why not do a drive-by instead of having a minion attack him from a crop duster? Hitchcock himself acknowledged the scene makes no sense, but justified it since nobody notices while watching the film.
Hitchcock himself developed a case of it for the scene where Eve and Leonard covertly talk using two phones at an airport. He held off filming the scene for a while, then apparently came up with a way it was possible and shot it, though he never told anyone what it was.
Misaimed Marketing: Movie theaters reportedly gave children coloring pages of such scenes as Roger getting chased by the crop duster and Eve hanging off of Mount Rushmore.
It was also featured on the Turner Classic Movies program Essentials Jr., which is marketed towards families and younger viewers, and usually features softer fare.
Spiritual Adaptation: James Bond was still a popular book series when this film came out, but it essentially codified many of the elements that typify Bond. Morally ambiguous femme fatale spies, Affably Evil supervillains, sexually ambiguous dragons, use of Monumental Battle and wild action sequences. Likewise, Sean Connery's turn as Bond, as a more suave individual than his literary counterpart was based on Cary Grant's performance in this film. Indeed, Hitchcock who initially considered adapting James Bond was upset that Albert Broccoli (who he knew personally) ripped of his film for many of the early Bond films.
