No, but it does make more marketable, a remake of the grudge will make more money than the original version.
The original version will never get a wide release, because then it get crushed by the other competing movies that are in English.
America is most navel gazing society in the world, so that's not going to happen.
Japan may have a better animation industry, but America has a better live action industry. I mean Iron man would have better effects than any Japanese movie and more famous people, that would bury a Japanese movie with no famous people and inferior effects, in direct competition. It would not survive direct competition.
Expecting a foreign movie to do well in the US, is like expecting a third party to take the white house, not going to happen in this lifetime.
Maybe, there are many of Hollywood films with good effects and good scripts.
It helps. Well you might think Pokemon the movie is fine art.
The thing is for foreign movie to work in the US, it neeRAB art house cred, which death note doesn't have, Persepolis does, not Death Note. Its a thriller, not art house.
Is the death Note movie better then say the Canadian film the Sweet Hereafter, see that's in English and is a foreign film, that would be more marketable and it didn't get a wide release.
Besides otaku fandom is there any reason why japanese films should get a major release, when no other major foreign filsm get the same treatment?
