The history of cinema is littered with examples of this cross-fertilisation A fistful of Dollars is a good example, an Italian film using a Japanese template (Yojimbo) set in an American Western milieu (Itself a total fiction), or Casablanca - THE quintessential Holly Golden Era film was directed by a Hungarian, with music by an Austrian, photographed by an American - the only significant speaking parts NOT played by immigrants were Rick and Sam.
I once talked to an American about Hollywood and said "US films are more popular than Canadian" and she said "But Hollywood doesn't represent US culture."
I didn't understand at the time but later I did.
There have been American filmmakers--John Ford and DW Griffith for example, who reflected regional American voices and ideas. THE PRISONER OF SHARK ISLAND is a Southerner-focused story. It is amazing they made it given some of the content and perspective. Not even GONE WITH THE WIND was so favorable to the Southerner side of the war.
Casablanca, skillfully made though it was, is war propaganda. It didn't do well when released--understandably--why would US audiences want to embrace a movie that promoted an ongoing war? It's amazing how that film is misinterpreted. It is not a love story--Ingrid Bergman said she didn't see the love story in it. The love story is Rick rediscovering his desire to fight and Claude Rains joins him for pragmatic reasons. That is what the movie is about. Two men, one a disillusioned idealist, who, thanks to Victor, sees that he has to get back into the fight in order to find himself. And Renault, cynical corrupt pragmatist, who takes whatever side is more powerful at the time, joins up but he's the most realistic character because he's only thinking of himself.
Ilsa is told to prostitute herself in order to support the war. She doesn't love Victor and Rick tells her you need to stay with him to keep him focused on the fight.
Homer it isn't.
Hollywood was accused of wanting to get the US into the war--I wonder about a film like The Adventures of Robin Hood since it was unusual given that Robin Hood is not only depicted as a noble, but he's unapologetically seeking to defend the homeland from foreigners-(despite his romance with a Norman Maid Marion)-he even criticizes King Richard for going off on foreign crusades instead of defending the homefront-that opinion would be called fascist today. And yes--it isn't shot in England and most of the cast is from every corner of the globe. Tasmania, South Africa...
By contrast, the Hammer Films' Sword of the Sherwood Forest, is closer to the source location, and has a very different story and approach. This is what you expect--different strokes for different folks.
There's a distinction between Universal horror films of the 1930s and Hammer films of the 50s and 60s too. Someone defined the difference by saying the Universal approach was rooted in the Wiemar era of German film while Hammer was Gainsborough and period drama.
Why is the approach different? Because the background and heritage of the filmmakers and producers and writers are different.
Different strokes for different folks. That is how art works.
Variety, different heritages, different thoughts and ideas.
It is impossible to make a film that is equally acceptable to all people. You'd have to reduce it to abstract color patterns.
The trouble is, there are a few films that are getting Western attention--corporate attention---PARASITE for example--and yet--when are we going to see a film that is all Gaelic being promoted at the Oscars?
Probably never because there is no desire to promote or celebrate regional European voices.
Hollywood has made films that, despite their intense multicultural approach, work as an entertainment if not cozy or identifiable to any particular group of people--but these days, they have stripped the European origins of the art form so much, that it has become chaotic and increasingly irrational in theme and moral viewpoint.
You cannot make an art work that is equally acceptable to all societies and people.
It is impossible.
