"Tekkon-Kinkreet" was one of the my favorite Manga written by Taiyo Matsumoto. His picture is unique and feel nostalgic and the story line is good.
I surprised the movie was directed by Michael Arias ... and the screenplay was Anthony Weintraub ... both of non-Japanese. But they succeeded to represent Taiyo world(old and not clean Japanese town) well. I would like to appreciate their interest in the Japanese culture and their great works.
Here is the information site of Tekkon-Kinkreet in English.
