the need to see one's self on the screen is not american, it is human. wealth, however is in the hands of the few, so remaking movies is a luxury. most of the time you must settle for localizing the existing movie with subs, dubs, or title changes.
every country would reshoot movies if it made business sense. most of the time, it never will make sense for small markets to do so. it does make business sense for americans to do it in many cases.
if you look at box office numbers, the domestic american numbers often match the worldwide take. it has not been a totally one way street, however. many american movies are severely watered down so they will appeal internationally. many of our movies have a formula that emphasizes broad themes that translate across cultures (love, revenge, heroism, etc.) and feature stars that the widest number of moviegoers will want to see (much of the world is sorta uncle tom-ish, so movies with black leads are said to perform worse internationally while white people seem to be the world's acceptable default movie star) under this international system, american movies with decent budgets cannot risk money on casting actors who may be in a low position internationally (fewer black actors than the 70s-90s) and these movies cant experiment with narrative. they also cant be too american, so focusing on issues that are very relevant to us but not relevant at all internationally is something almost exclusively for small budget and indie flicks.
so right now, good international flicks never get shown to a wide american audience in original form, and american movies have become soulless, lowest common denominator flicks in order to appeal to international audiences. it's all fukked up
