Here is an amazing mockup for a Shadow of the Colossus anime by artist MetalHanzo, based from the classic PS2 game, which is soon to get a HD reboot alongside its older brother, ICO.
I can imagine now, as a silent anime with acts, musics and sceneries to convey the story, and minimum dialogue.
Unfortunately, 99% of the anime industry in Japan right now is more concerned with underage girls, incest, and panties….nothing good could possibly from a SOTC anime with this mentality. There are about 3~4 anime studios maximum who would actually allow SOTC to maintain its dignity.
Oh well, on can always dream…
