Whoa. I just watched Tekkonkinkreet and was entirely blown away. this animated film is a visual powerhouse of style, color and imagination. The title is a play on "Tekkin Concrete", a Japanese word meaning "reinforced concrete." This lovely, feature-length film was released in 2006, directed by Michael Arias and animated by Studio 4°C (the studio that produced "The Animatrix"). It was adapted from the original manga "Black and White," a three-volume series by Taiyō Matsumoto, serialized between 1993 and 1994 in Shogakukan's Big Comic Spirits. Set in the splendid, bustling Japanese metropolis of "Treasure City" the tale centers on a pair of orphaned street kids: Black, the older, clever and "dark" personality and White, a sunny innocent. Together they fight off rival gangs, Yakuza professionals and bad-ass alien tough guys. The climax comes when the two are separated, and Black's darker nature begins to assert itself.
