I'm going to second what knives and matrixschmatrix said. The MGM/US Blu-ray of
Manhunter looks fantastic (and is region free), but is barebones. The UK/region B Blu-ray from Optimum was victim to some overzealous noise reduction that wiped out detail (
lCheck out caps-a-holic's comparison between the Blu-rays) So, buy the MGM Blu-ray and, if you have to have special features, buy both the OOP Anchor Bay "theatrical" cut and AB's OOP Divimax Director's Cut or, if it is cheaper and you are region free, the Optimum Blu-ray, which has, I think, most but not all of the special features found on the two Anchor Bay releases (pretty sure the Optimum is missing the stills galleries that are on the Divimax DVD, but has the featurettes from the "theatrical" DVD and Mann's commentary from the Divimax DVD)
