Since WEDNESDAY 19.11.08 at news-stands. It's really worth seeing. Who’s Who in CITIZEN HAVEL at film web : http://www.obcanhavel.cz/index.php?lang=english
I have no idea about availability outside CZ. It's possible to order it for example at : http://www.arara.cz/product/190131 but it's much more exepensive.
What those not in the Czech Republic might not realise is that the DVD Yvan was talking about has been brought out by the newspaper Mladá Fronta Dnes for the princely sum of 49kč. All the papers are selling all sorts of DVDs such as films and concerts, all for about 49kč - wonderful value! They're just in a simple card sleeve instead of a plastic clip-fastened case but even so, I don't know how they do it for the price - it probably means that the ordinary DVDs are grossly over-priced!
CITIZEN HAVEL (Obcan Havel, DVD) with English/German subtitles now available at Levne knihy for 39 Kc. Really worth seeing. http://www.levneknihy.cz/DetailZbozi.aspx?z=64529
