Grave of the Fireflies (1988)
Takahata's 1988 Studio Ghibli WWII drama. Two siblings starve in firebombed Japan.
Actor: Ayano Shiraishi
Ayano Shiraishi voiced Setsuko in Grave of the Fireflies at five, and Isao Takahata recorded her reactions to genuine circumstances instead of directing a performance, which is why the character is so difficult to watch.
