Turner Classic Movies will be showing Takahata's Grave of the Fireflies this November 12 at 10:00 est. This will be the English-language version. Be sure to tune in, tell all your friends, and send an email of thanks to Turner Classics.
While I'd clearly prefer to see this movie subtitled and in its original language, my first viewing of Fireflies was on VHS, which was a dub. It's was okay (I bawled often enough), even if not as good as the Japanese actors; Setsuko was played by a five-year-old in the original cast, and is clearly better than an adult actress (in the US dub) trying to sound like one of the Campbell Soup Kids.
Anyway, be sure to tune in, turn on, and drop...how does that go?
