Because it's still not yet out on DVD anywhere in the world (and for that matter, hasn't even made it to American cinemas just yet), I content myself with playing with and gazing at my beloved Ponyo plush and occasionally going online to check out Ponyo trailers.
The very first of these that I discovered was the original Japanese trailer that I found cute and fun. Then came the French trailer which I really do think is a lovely piece of art in and of itself.
For the life of me, I can't decide whether I like the Japanese or French trailer better as each has its merits. (I love the Japanese voice of Ponyo -- even when I can't understand what it's saying! -- but also love the French trailer for using that wonderful Joe Hisaishi composition that also features in the film proper.)
Still, one thing's for sure: Both are miles better than the American version -- including at capturing the movie's sense of magic along with beauty. So should you deign to check out the American trailer, do then go back and watch either of the other trailers to wipe the bad taste in your mouth that the stupid version temporarily left behind!
