Even films tied to already released television series can get held up for years. Here's seven anime films still waiting for their day in the states.
Piano no Mori A top-grosser in Japan in 2006, Piano no Mori is a coming of age film based on a manga by Makoto Isshiki and directed by Masayuki Kojima (Monster). It follows two elementary school boys, one from a pedigree family of pianists named Shuhei and another from the red-light district named Kai. An abandoned piano in the forest brings them together when Shuhei discovers that Kai is the only one that can make the rundown instrument perform. Madhouse animated the picture which performed surprisingly well for a stand-alone movie.
Taifū no Noruda (or Noruda's Typhoon) is the first full-scale production by Studio Colorido, who up to this point, had animated some impressive shorts and commercials for Marukome Miso. The story is a combination of dealing with everyday problems, in this case protagonist Shūichi is in a rough patch with his best friend Kenta, and the supernatural when a mysterious girl from space brings a typhoon with her. The movie only runs about half an hour and shows great potential for an up-and-coming studio. I'd like the film to be brought over if only to support Colorido's endeavors in the hopes that it could create longer, more fleshed out works in the future.
