Noé had a vision, reportedly sparked by watching Robert Montgomery's Lady in the Lake and Kathryn Bigelow's Strange Days on drugs.
The entire film is shot from Oscar’s point-of-view evoking Hollywood classics such as Robert Montgomery’s Lady in the Lake (1947) and the first third of Delmer Daves’s Dark Passage (1947) as well as first person computer games, the opening of Kathryn Bigelow’s Strange Days (1995) and Jonas Åkerlund’s music video for The Prodigy’s single “Smack My Bitch Up” (1997).
Director Kathryn Bigelow and writer James Cameron took the same idea a decade later and cyberpunked it up as Strange Days (1995), which opened with a truly extraordinary POV action sequence and later cooked up a frightening first-person rape scene.
Pompous with pregnant implications, mean in story, and exhausting rather than exhilarating in technique, the interior and afterlife journey is not a patch on Fantastic Voyage, Yellow Submarine, 2001: A Space Odyssey, Performance , Altered States, Tron, Strange Days and a long et cetera.
The concept of shooting the entire film from the protagonist's point of view is not completely unheard of; in an interview with the Montreal Mirror, Noé has cited the "virtual-reality snuff films" sequences in Kathryn Bigelow's "Strange Days" and Jonas Ã
kerlund's music video for The Prodigy's Smack My Bitch Up as possible influences, to which I'd add Julian Schnabel's "Le Scaphandre et le papillon", about half of which was shown through the main character's POV.
