The Nodame Cantabile live action drama will never be topped for awesomeness.
But seriously they cast some pretty boy from an insipid boy band (and I say this as an idol fan) as Ed, not an actual actor. So.
Yeah.
(they do this a lot, agencies that idols belong to pretty much run everything entertainment-wise in Japan, so unqualified people are always getting acting jobs. this is why no one takes modern japanese film seriously)
