Iwai Shunji Film Festival (IWAIFF) is an odd duck. Once a month or so, an online magazine of sorts is updated with a new "volume" featuring short videos of interviews with actors and professionals who have worked with Iwai, plus storyboards, MP3s and other odds and ends.

I'll be creating blog posts for each volume (Volume 8 just came out) and adding hopefully much more on Iwai in the coming weeks and months.
