Hate to patronise our excellent Stateside cousins, but they really don't have the subtlety for witchcraft-humour, and they always have to feature a Jennifer Aniston lookalike (in this case Elizabeth Montgomery), to represent the all-American beauty, which just seems to miss me every time.
This was not only the pilot episode, but the only one of the series that I had ever come across, so I thought we were starting off well when the lovely, mystic Agnes Moorehead suddenly popped-up from nowhere, assuming that this was our witch. But she turns out to be playing only a minor role as a sort of witch-mother, and the actual witch is Montgomery herself, who has just married the naive Dick York (the young schoolteacher from 'Inherit the Wind') and is determined to live a conventional suburban life. Deciding that they should keep no secrets from each other, she confesses to being a witch, and he makes the mistake of asking her to prove it. This leads to some rather unfunny stage trickery, before she swears to give it up for good.
The husband now gets an unwelcome visit at work from his ex (a wonderfully malicious Nancy Kovack), who invites them to a dinner-party, pretending it's casual-dress, when in fact it's a formal evening occasion. After putting up with hours of repeated humiliations, Montgomery is stung into reviving her forbidden powers, in ways we can't reveal...
