A beautifully crafted nightmare, Borowczyk's greatest masterpiece as well as his darkest and most personal. He re-imagines Jekyll/Hyde (and later his demonic bride) as libertine heroes, murdering and raping authority figures and laying waste to the upper middle class all in pursuit of pleasure. The last few scenes where the couple go wild, destroying their possessions, fucking and biting at each other's flesh is haunting and hypnotic.
