"Ponyo" is about a goldfish that longs to become human. Now, that might sound a little strange, but Miyazaki has the amazing ability to take the most absurd childhood fantasies and turn them into something believable and mature. This is more than what can be said for most movies aimed at children nowadays (I'm talking to you, "Beverly Hills Chihuahua").
I'm usually wary of foreign films that get dubbed for their U.S. release because I'm a subtitle guy. But John Lasseter, another animation mastermind who created Pixar, is producing the English language version. He has produced most of the other English translations of Miyazaki films. Each film has made it smoothly from Japanese to English. I have no doubt this one shouldn't either.
I will try and forget the fact that Miley Cyrus's sister and a Jonas are in this movie, because the cast also includes Lily Tomlin, Cloris Leachman, Liam Neeson, and Tina Fey amongst others. Everyone knows you can't go wrong with Tina Fey, and the addition of Hayao Miyazaki just makes it all the better.
