You might've never heard of Hayao Miyazaki, but he's responsible for some of the best animated movies to come out of Japan, including the Oscar-winning Spirited Away, Ponyo, Princess Mononoke, and many others. He has unusual control over the translation and handling of his movies here in the States. For one, he does not grant any merchandising rights, so there are no Ponyo video games or Spirited Away Happy Meals.
However, it didn't used to be like this. One of his films, Nausicaa of the Valley of the Wind, was severly cut and Americanized to the point of being unrecognizeable from the original. This made him so angry he decided not to allow that to happen anymore.
When it came time to translate Princess Mononoke (one of his most acclaimed films) for US audiences, he was firm in his no-cuts policy so that the film is as faithful as possible to the original. One of his producers thought it'd be a good idea to send Harvey Weinstein, the co-founder of Miramax, a samurai sword to remind him of that. The producer did this after Miyazaki went to New York to meet with Weinstein and was 'bombarded' with requests for cuts to the film, which he absolutely denied. Miyazaki said "although I was bombarded with this aggressive attack [...] I defeated him."
