Criterion "Special Features": s/d

Too often I'm in too much of a hurry to get my Criterion rentals back to the library, but I've been trying to watch more of the supplements on these discs while I can. I didn't find much on the Vampyr disc that was too worthwhile, but I just renewed Island of Lost Souls so I can go through the interviews and whatnot. Problem is, I find, that watching the special features can usually take up the same amount of time as watching a full-length movie (and often much longer), and my leisure time is sadly limited these days.

So, what are some of the better supplements (interviews, documentaries, bonus films) that you have come across in your Criterion viewing? What should I not be skipping?

the Bunuel docs included with The Exterminating Angel and Belle de Jour are useful, and most of Robert Altman's commentary tracks are insightful.

Most of the stuff is inessential though.

Short Cuts is one of the few that I actually own, so that's always given me a reason to put off delving into the features. I've heard his Player commentary and yeah, he's actually worth listening to for 2-3 hours.

Will have to spend some time with the Belle de Jour disc on my next re-watch, if I can find it. Have only ever seen it on TCM.

I forget which has Don Luis himself mixing a Bunueloni.

there's a TV hour (South Bank Show) on the French Lt's Woman set that's 'better' than the film. (Irons, Streep contemporary interviews good too)

Agreed that Altman's commentaries were consistently among the best I've heard.

what's the doc where Jean-Claude Carrière and Luis' son go visiting every city he ever lived in? That was great.
