This is my first comment on IMDb because I've never seen a video that deserved praise more than this film. I can't believe that there are no comments already - this feature is too good to be so unknown.
I saw this short film on PBS in 1994 and now my wife and I watch this VHS film every Christmas - it has become a tradition with us. It is one of my favorite stories. The incredibly wonderful "animation" is straight from the Nicola Bayley artwork for the Antonia Barber book. The narrator (reader) is Sian Phillips and she does a marvelous job. Your enjoyment will be increased if you love cats.
Two complaints: (1) I can't get my wife to make me a star-gazey pie and (2) I wish it would come out on DVD...
