On the director's cut, Gilliam is featured on the commentary track, and he's always a joy to listen to. He likes himself and his work, and he has no problem discussing either. It's good to see this cut with the commentary track, because it's amazing how different it is from the original vision. Keep in mind, that all the footage was shot by Gilliam, but edited by someone without his supervision, and you will definitely see how editing can change everything from character tone to storylines. Once you figure that out, you're good to go.
All version is just okay.
It's a full frame transfer, and seems dark and foggy. This DVD transfer looks almost exactly like the laserdisc transfer, so it's probably the print, not Criterion. But as a curiosity piece, it's perfectly done. This isn't the reason you're watching Brazil , so I think it's fine. I'd like to also give a brief review for the Universal DVD edition of Brazil , because it has some importance in all this.
