just some behind the scenes stuff set to Ifukube music. probably fan made since they didn't add music from the movie, which is too bad. I'm glad someone filmed stuff like this. these days, you get all sorts of mostly useless making of extras on DVDs, since it's so cheap to record digitally. recording with film is a bit different.
and anyone who says these movies are just thrown together with no care or anything is completely wrong. this should easily prove that. all this is handmade, not a single pixel manipulated. gotta love it!
