Apparently some movie called Mo Xiaobai’s Sea Monster Diary (莫小白的水怪日记) came out in January. Or was supposed to. It seems to be about an overimaginative kid’s summer vacation. You can download the trailer here, which uses a song by Joe Hisaishi from the Takeshi Kitano film Kids Return (which is awesome). It also reminds me of another Takeshi film, Kikujiro.
