Janet Leigh stars as a neglected wife who's fed up with her husband and his insect collection; she's had a secret affair with her spouse's business partner and thinks if she can get rid of her hubby, she can find happiness with Husband #2. So far, so good--but when Leigh takes care of her evil business via a witchy potion, her husband's bug collection comes back for revenge. This was the first episode of William Castle's anthology series "Ghost Story" to air under its new title, "Circle of Fear", although all the talents behind the camera are the same (unfortunately, weekly host Sebastian Cabot has been unceremoniously dropped). Disney-veteran James Neilson directed, but he isn't able to do much with Rick Blum's teleplay without a larger budget to back him up (this is an instance when an adroit special effects team was badly needed, though one that a television budget probably couldn't sustain). Writer Blum has the semblance of a good idea here, and it must have been disheartening for him to see it all fall apart in visual terms. Leigh runs around swatting at flying bugs we can't see, and the final twist is not only silly but stupid.
