I am a massive, massive fan of genius filmmaker/animator Hayao Miyazaki, and you should be, too. If you haven't seen the master's films -- and I don't use the term "master" lightly; he is absolutely, without question, the finest animator working today -- you need to, now. Every one's a gem, from his 80s masterwork "Nausicaa of the Valley of the Wind" to the gloriously adorable "My Neighbor Totoro" to the magnificent "Princess Mononoke" to my personal favorite, 2004's "Howl's Moving Castle" and everywhere in between, he doesn't have a single dud in his catalog, nor is he likely to, ever. His attention to detail is astounding -- every texture, every cloud, every mountain is lovingly rendered with absolute care, and it makes his films a joy unparalleled.
His new film is called "Ponyo On A Cliff By The Sea," and it's due to be released domestically sometime in 2009, though it was already a runaway hit in Japan. I've read that Miyazaki took special care to render water and waves in this one, which takes place mostly at sea. It's the story of a goldfish princess who wants to be human -- kind of a twist on the "Little Mermaid" myth. It is heart-meltingly adorable.
When it comes out, go see it. And rent every single one of his other films, if you haven't already.
