Bondil-Poupard astutely observes that "in alluding -- whether consciously or not -- to his many and varied aesthetic influences, from Romanticism to Expressionism, from Symbolism to Surrealism, [Hitchcock] appropriated, assimilated and transcended them. Such is the hallmark of any great artist."
From there, she reaches beyond Dali to discuss surrealism in several of Hitch's movies.
Bondil later adds: "With tongue only half in cheek, I leave you with the contention that the most Dalinian of Hitchcock's films is actually North by Northwest. The film, which even its creator admitted was like one long dream sequence (he compared it, incidentally, to a painting by [WWI avant garde artist] Christopher Nevinson), is pure fantasy." Regarding the movie's improbable locations, such as an air strike in a desolate cornfield and the chase across Mt. Rushmore, she adds the reminder that "image and imagination, after all, are derived from the same word."
I'm not sure which specific Nevinson painting Hitch might have had in mind, but here's one that suggests the beautiful terror of death in the sky, which, in spirit and tone could anticipate the crop duster scene:
La Guerre Aérienne, 1918
We are so often treated to the iconic clip of Cary Grant running from the biplane that it's easy to overlook that much of the three-minute sequence is dedicated to lingering shots of the menacing aeroplane itself.
