Our son absolutely loved this episode. I thought it was pretty funny, but it never quite rises to a great bit early on. Lady Collingford has decided that their house, which has 184 rooms, is haunted, in part because she keeps hearing this peculiar sound. Elspet Gray then gives this hilarious impersonation of Geoffrey Bayldon’s “tch-tch-tch!” noise and I hooted.
This rapidly descends into the sort of “he went thataway” farce perfected on American Saturday morning shows. Lady Collingford hires famous ghost hunters, played by Dudley Foster and David Cook. They’re a couple of scam artists who have wired the house with speakers, and Cedric has decided to try and spook them with a bedsheet, and Catweazle has decided that tonight, of all nights, is the right night to ask the house’s spirits to help him find the hidden gold in the house. Our son was howling with laughter; this was clearly one of his all-time favorites. Moray Watson is playing an upper-class twit in this series, but he defines the term “long suffering” tonight.
Dudley Foster died in early 1973, only 48 years old, but he appeared in just about everything a fellow could possibly do in British film and TV before then. Foster was cast as the villain Caven in a 1969 Doctor Who serial, “The Space Pirates,” which is the last incomplete story of that program’s run. Bizarrely, Foster appears in the five episodes of that serial that are missing, and not in part two, the only episode that survives. That strikes me as a little karmically unfair.

Dudley Foster sadly committed suicide. He was a lovely,talented actor,good at comedy as well as drama. I enjoyed watching him in this episode of Catweazle.
