In this old Hollywood romance, Gillian Holroyd is a modern-day witch who becomes interested in her new upstairs neighbor, publisher Shepherd Henderson. After learning that Shep is going to marry her college rival, Gillian puts a spell on him with the help of her
Siamese, Pyewacket. The spell works—Shep becomes smitten with Gillian and breaks up with his fiancee on the morning of their wedding. As Gillian’s familiar, Pyewacket appears in the film several times, perching on Gillian’s shoulder, jumping onto artifacts, and running across streets. It is reported that the role of Pyewacket was played by 12 different cats.
