Some further tiny news bits:
An adaptation of Samurai 7, based on Seven Samurai, will be staged at the Shinjuku Koma Stadium in Tokyo in November this year. (source)
Meanwhile, the recently wrapped Chinese film Ku Zhu Lin is apparently some sort of an homage to Seven Samurai. I do not seem to find any specific information about the movie on the web, but the English title is Bitter Bamboo Grove. You can see my source and some pictures at China Daily.
