Witches' Brew

This remake of Fritz Leibers novel Conjure Wife (previously filmed as 1944s Weird Woman and 1962s Night of the Eagle AKA Burn, Witch, Burn) is more of a horror spoof, as three women use witchcraft to further the careers of their respective professor husbands. When a higher position becomes available in the university, they turn on each other, and no one is safe.
