"One of Barbara Steele's most impressive vehicles, and one of the cornerstones of the classic Euro Horror Renaissance (1956-66), Castle of Blood is perhaps the best film by the erratic, prolific Antonio Margheriti. A very nifty ghost turn involving a perpetual cycle of sex and murder among a quintet of libidinous ghosts, the story brings in vampiric ideas as well. Edgar Allan Poe makes an appearance as a character, which is all well considering that the story attribution to him is a complete falsification." - Glenn Erickson, DVDTalk
