There's a decent edition here in the US, that I never picked up. I imagine some of the same features. Odd to think that film is 40 years old, it still seems fresh to me. The Young One is the only film in that set I haven't yet seen, but I'll take care of that before too long. It, along with Tristana haven't been released on DVD here, but thankfully Bunuel was rather well represented on VHS. I guess though for every worthwhile film that comes out there, we have one as well to covet. 

The blatant re-releasing though is something of a problem. So many films are available in glorious editions and then get re-released with nothing more than an additional featurette of self congratulatory bullshit, like the "special" edition of Office Space.
