Japanese auteur Oshii's beautifully realized sci-fi spin on Arthurian legend has been released in Japan in a boxset containing a Blu-Ray HD version of the film, an SD version, and a Japanese-language booklet. The sort of picture which seems to call out for high-res exhibition, Avalon reps one of the more unique films (both in terms of content and production - it's a Japanese film, produced in Poland with Polish-speaking actors) to come around this decade, and it sounds like this release offers an outstanding visual experience for those willing and able to double-dip. The price tag clocks in at just about $90 - a whopper to be sure, but potentially worth it to true fans.
Worth noting that the BR disc is classed as "Region A", meaning it will play in Japanese and North American BR players (but not those in the UK, China, or Russia).
Region A won't play in your Euro or Australo-player either. Region coding is one big reason I'm sorry that BR looks like it's going to win the format war, but at least as an American I'm in the same region as East Asia (excepting China, but whatever comes out in China'll come out in Hong Kong.)
But yay for English subs on Japanese high-def disks! I think only Ghost in the Shell 2 has gotten English subs out of all the Japanese blu-rays of Japanese movies.
