1) Is this even possible? Is this even desired?
Certainly possible and desired.
2) Assuming it’s possible/desired, or close to, what films have come closest either overall, or by a particular metric, and why/how?
In addition to the films already mentioned, there was The Godfather, Lord of the Rings, Gone With the Wind, Star Wars, Jaws, Singin’ in the Rain, etc.
*3) What makes a film popular? *
No one knows. If anyone in Hollywood figured that out, they’d be billionaires. You need the basics – good plot, interesting characters, good lines – but that’s only the start.
3b) Assuming you have an otherwise amenable to popularity film, how do you inject deeper meaning or other elements to make it critically acclaimed?
You don’t inject it. It has to be there organically. And you don’t have to add deep meaning to be critically acclaimed. Star Wars was loved critically from the beginning; any deep meaning in it was purely accidental.
**4) What makes a film critically acclaimed or otherwise considered important or meaningful or truly moving? **
The basics (mentioned in #3) are all there, and it has to have some sort of emotional connection with the viewer.
4b) Assuming you have an otherwise amenable to critics film, how do you inject whatever pushes a film into popularity / financial success?
You don’t inject it. It has to be there organically. You get the basics right and tell a good story.
*5) What makes a film speak to its time and/or is topical/generational? *
Impossible to say. The subject matter is part of it, but it also has to have the basics.
5b) Assuming you have a film that speaks to its time and/or is particularly topical/current generational, how do you make it more universal and/or standing the test of time or classic, or still worthy decades later?
It has to be there organically from the start. And, frankly, trying to figure out what will speak generations later is a crapshoot. Casablanca, for instance, was not made to be a classic film – it was a studio system picture, with the actors not even sure of what the ending would be. Somehow, it worked.
6) What makes a film universal and/or standing the test of time or classic, or still worthy decades later?
Impossible to say. Again, there’s Casablanca. I don’t think anyone involved in it ever thought it would be considered that highly, or even remembered a year after it was released. Singin’ in the Rain is considered on of the best films of all time; Adolph Green, who co-wrote it, found that absolutely amazing. The film was simply a way to write a story around a catalog of songs.
6) Assuming you have said universal film, how do you make it more specially currently appealing / topical / etc.?
If the film is universal, it will have topical appeal, too.
