Kagemusha is, probably, the best example of cinematic overkill where nobody actually cares. Cinematic overkill is when someone constructs a complex multi-layered movie, stage epic-battles, introduce likeable and complex characters without having a very complicated message. The message of “Kagemusha” is simply this: If you pretend long enough to be something else you’ll become it. Too simple, maybe, for what’s delivered.
A grand spectacle of samurais and shoguns. What happens to the doppelganger when the original dies? Does he flitter out of existence or does he find his own. Kagemusha (shadow warrior in Japanese) is the story of a thief who is to be hanged, but is saved by a warlord’s brother, Katsuyori Takeda, because of a peculiar resemblance to the king Shingen Takeda.
