The official website for Su-jin Kim's Dreaming of Light (Garasu no tsukai) is online. There's an English-language synopsis for the movie here on the website of Gold View Y.K. (Y.K. Gôrudo Byû). The screenplay for the movie was written by Jûrô Kara, based on the eponymous novel, which he also wrote. The movie's principal cast is as follows: Megumi Satô, Takuo Inari (given name may be "Takuô"), Kimiko Yo, Jundai Yamada (he's also in Jun'ya Satô's Yamato (Otokotachi no Yamato)), Naomasa Musaka, Miyuki Nakajima, Renji Ishibashi, and Jûrô Kara.
BTW, there's an English-language synopsis for Mitsuo Yanagimachi's Who's Camus Anyway? (Kamyu nante shiranai) here on Gold View's site.
