Bell Book and Candle (that is the official title without any comma. The play title is with the comma) is a 1958 romantic comedy, based on a Broadway play by John Van Druten. It stars James Stewart, Kim Novak, Jack Lemmon, Ernie Kovacs and Janice Rule. The real star though is Pyewacket, a beautiful Siamese, lucky enough to be photographed with the lovely Kim.
The origin of the name Pyewacket goes way back. The following is from the IMDB.
Pyewacket was one of the familiar spirits of a witch detected by the “witchfinder general” Matthew Hopkins in March 1644 in the town of Maningtree, Essex, UK. He claimed he spied on the witches as they held their meeting close by his house, and heard them mention the name of a local woman. She was arrested and deprived of sleep for four nights, at the end of which she confessed and named her familiars, describing their forms. They were: – Holt – Jarmara – Vinegar Tom – Sacke and Sugar – Newes – Ilemauzer – Pyewacket – Pecke in the Crowne – Griezzel Greedigutt – Hopkins says he and nine other witnesses saw the first five of these, which appeared in the forms described by the witch. Only the first of these was a cat; the next two were dogs, and the others were a black rabbit and a polecat. So it’s not clear whether Pyewacket was a cat’s name or not. As for the meanings, Hopkins says only that they were such that “no mortall could invent.” The incident is described in Hopkins‘s pamphlet “The Discovery of Witches” (1647).
