Mario Bava's breakthrough film Black Sunday aka The Mask of Satan has not dated as well as might be hoped, I'm afraid. Photographically it's sporadically interesting, with some good in-camera make-up effects achieved through lighting changes and a clever use of long lenses to make his cramped sets look much larger than they are, but his story of an accidentally revived witch and her lover taking her revenge on her descendants (inspired by a story by Gogol, no less) tends to take its time and offers few surprises now the novelty of the slightly-stronger-than-the-norm for the era gore has worn off. Not bad, just very familiar even if you haven't seen it before.
Anchor Bay's Region 1 NTSC DVD includes the original Italian 'international version' rather than the US version, with audio commentary by Tim Lucas, stills and poster gallery, US TV spot, US trailer and international trailer, as well as trailersfor Bava films Black Sabbath, The Girl Who Knew Too Much, Kill, Baby... Kill! and Knives of the Avenger.
