this be the bad movie i have ever see in my entire life and i be sorry i pay money to buy the dvd that i will throw in the trash . erotic no female nudity technically yes about 1 minute in total sex no for practical purpose this be not base on the novel by the marquis de sade while in fact in the interview the writer admit he rewrite the story to accommodate tyrone power daughter who could not act . so there be no black mass or anything of the original book except the two sister originally be teach by nun in a convent . this be a shear waste of money on the part of franco that could have be his masterpiece with the expensive set and costume that be absolutely splendid . jack palance be totally miscast and even if he be sober it would have make little difference . the same be true with klaus kinski because his performance be too remote and do not narrate the story all the way through . franco say he ask orson well to play the part of the marquis de sade and again totally wrong if you be go to make a porno movie . i have no idea what he be think . the story be so confused that it fail to make real sense because it deviate from the original novel so much . this movie be not a porno or anything else and it be just a big nothing .
