I think it is a pity that they feel they have to do it. It can be disastrous. A good example of that is the very good french movie Nikita by Luc Besson that became The Assassin (aka Point of No Return) with Bridget Fonda in the main part. But the two that were made from swedish ones, The Girl with the Dragon Tattoo and Let Me In were OK even if the originals were better. And sometimes people don't seem to know that the movie is practically photocopied as Leones first Dollar-movie was. For A Handful Dollar is taken, practically scene by scene, from Akira Kurosawas Yojimbo - The Lifeguard. And the good western The Magnificent Seven is taken directly from The Seven Samurai, also by Kurosawa. The thing is not that they, the hollywood people i mean, do a bad job but that the american version keeps people away from movies that are really good. Also by using the american people to only see english speaking movies they miss so much. German, french, japanese, chinese and spanish movies and so on.
