My personal thoughts on this are that shooting on 35mm film cameras is by a huuuge margin the cheapest anyone can shoot photos in high fullframe quality. Or use amazing lenses that aren't available on smartphones. Like e.g. 300mm zoom lens, macro lenses and especially beautiful portrait lenses.
But for movies there isn't this bang/buck calculation. And analog shot movies are to my knowledge more medium format with a very specific look. Medium format has the combination of long focal lengths and big field of view that isn't really replicable with digital fullframe cameras
Lastly, I like the grain of analog movies. I can't help it.
Recently watched: The Shining (1980, analog), IT (1990, analog), Geralds Game (digital), In the Tall Grass (digital). All based on Stephen King novels and IMO good comparisons for digital vs analog.
