My wife and I watched a 1958 film, Bell, Candle, and Book.  The film stars Jimmy Stewart and Kim Novak and deals with witchcraft.  It was supposed to be a romantic comedy, but it was not funny.  Kim Novak is a witch, while her brother, Jack Lemmon, is a warlock (a male witch).  The only thing that I can recommend in the film is the one statement that witches, (because they are of the devil), cannot love.  Kim Novak sheds being a witch and when she becomes a human she has real emotions – she can cry and laugh and love.  Her brother does not understand that as he remains on the dark side.
