Thanks for the info on the UK version of this! I saw HKFLIX offering the Japanese version a few months back, and avoided that version because of the black bars. I just placed an order with Bensons, and I can't wait to see it!
I can't quite tell from your post, but if that's the FEJUI version you've ordered, cancel it immediately!
If you see the Fejui DVD, then you're bound to gain an all-new appreciation of the black-box censorship of the U.S. theatrical release (which is identical to the version shown occasionally on Cinemax). The FEJUI DVD version doesn't simply cover up the naughty bits via black boxes - it removes those scenes altogether! If you've seen the film, then you know this means some very extensive scenes were removed. In other words, DON'T BUY THE FEJUI DISC!!!!
(And, yes, the UK version is in the wrong aspect ratio - which is especially galling
since the aspect ratio is one of those "rules" of dogme-95! - but I don't know whether anything else is cut or otherwise altered.)
(I too am hoping Criterion comes through with this one.)
