In France only!
This week, 2 BBM dvds came out here:
* The collector's dvd, containing 2 dvds: one with the film, plus the trailer, plus several dozen still shots of the film and its making. The other with documentaries we've all seen: the making of the film (on how hard it was to get the project actually going); on being a cowboy; from film to script with Diana Ossana and Larry McMurtry; and an interview of Ang Lee. Most of the latter is on the British (and US?) dvd.
* The Prestige edition: contains all of the above, plus Annie Proulx's short story (in French), plus something which in French could either mean a card deck with pics of BBM, OR a bunch of actual photographs (probably the latter), PLUS a piece of the film that was used to shoot. Of course, this is a limited edition.
It would seem that there is never going to be any dvd with cut scenes or goofs, though.
