I've just found a Region 4 DVD for Breillat's Dirty Like an Angel (see my original post on the film here), under the Spanish title: Sucia Como un Angel. It's from the DVD company Film House, and apparently has a nice, widescreen print. Unfortunately, however, most reports say they have only added Spanish language options.
At least one website (http://www.mixup.com.mx/) does claim it also has English subtitles, however. I'm trying to find out (I've just sent an e-mail to Film House), but if anybody knows or can beat me to the punch in finding out, please let me know!
Update 11/28/08: No word back from Film House, but I talked to someone who sells these discs online and he assures me there are no English subs. Oh well. :(
