It was mentioned the other day on CBR's main page, is the news around the internet and is even on Blade of the Immortal's Wikipedia page, so, who's excited about this?
For those who have never read the comics (manga, if you want to be anal), a samurai is made unkillable after being given some kind of demonic maggots that constantly heal him. At first, it seems great, but he soon realises the down-side and the only way to get rid of the maggots is to kill 1,000 bad people. Cue the kind of ultra violence we all love about Japanese comics.
Personally, I can't wait to see this! I bought the first 4 or 5 compendiums when they published (with the publishers quick to point out that the samurai's outfit does NOT denote his hatred of Zion) and enjoyed them a great deal. Very over-the-top in places, but who can complain (and I'm sure that aspect will only appeal to Miike's quirky edge all the more).
