They've been showing this on ITV3 in the afternoons.
Currently watching this afternoon's episode on Catch Up written by John Cleese and featuring a young Mollie Sugden and a young Patricia Routledge who is a white witch. Very slip and quite attractive.
I saw one the other day with Richard O'Sullivan as the despicable creepy one. He played the part really well but he became quite normal in Man About The House and Robin's Nest. Shows what a good actor he is.
