Somebody here mentioned a New Star box set of all the existing (and maybe some forthcoming?) discs. If you're serious about getting your hands on everything, it might pay to wait for this, if it isn't apocryphal. The New Star editions are definitely the way to go. The best international editions are ports of these, and they're the only source for his best films.
EDIT: Here's one
Thanks for the heads up Zedz. Just received this today, good seller, week to arrive. They are listed on the ad as 4:3 full frame but only the first two are, the others are 16:9, most 1.78:1. They come as separate discs rather than a box (I wonder what he does with the non-subtitled ones and how I would love to see them with subtitles...) There is a seller doing a port of The Beekeeper on E-Bay as well.
The thread prompted me to watch the video of Eternity And A Day which had been sitting on my shelves for an embarrassing amount of time and I was very impressed indeed. Stunning composition, everything beautifully balanced and so pleasing to my eye (and Karaindreou's beautiful music as well). And I found it captivating, not slow at all as I had feared. I had previously seen Ulysses Gaze years ago and been less impressed but images from it kept coming to mind, the statue of Lenin sailing down the river (not laboured, like the tail fin of the plane in Apocalypse Now after they had left Vietnam), the crowds coming out onto the streets of Sarajevo when the mist came down, so I thought it was about time I tried more.
I remember a few years ago when I first started followoing film threads online there was word of a major Angelopoulos series coming from Canada I think (I believe it was referenced on the old pre-Eureka MoC website) which would offer the films plus extensive extras. Anybody know or able to offer anything on that score. AE have been on the verge of releasing a lot of his stuff for years now but that never comes either.
