When Central Park Media went under, we feared Grave of the Fireflies would be lost and become unavailable here in the US. Thankfully, ADV quickly picked it up, and they have recently released the DVD.
I am very happy to report that all of the excellent features from the Central Park version are present on ADV's release. The only change is the DVD cover, which, frankly, looks much better with its bold lines and dark colors.
Grave of the Fireflies is available on store shelves once again! If you haven't bought it yet, you owe it to yourself to add Isao Takahata's masterful film to your library. It will grip you and shake your emotions to the core; and I can think of no other movie that will shatter your Western assumptions and expectations of animation. If you've never been exposed to Takahata, you are about to be experienced. Bring Kleenex.
