John Roger Hammond, who passed on this day (8th Nov) in 2012.
He was an English character actor who appeared in many films and television series, including The Duchess of Duke Street (1976), Edward and Mrs. Simpson (1978), The Madness of King George (1994) and The King's Speech (2010).
.. but we remember him here as 'Boris', who appeared briefly in the last episode of the second series 'The thirteenth sign', who's balloon carried Catweazle away, originally aired on the 4th April 1971.
Great additional information Chas. Somewhere amongst my collection, I have a piece of film that Gary Warren sent to me. It is a little piece of film that he shot out the window whilst on set from Kings Farthing focusing on the balloon trying to be put up out in the grounds.
It's on cd. I will look for it. I have so much Catweazle stuff in my house, I usually say "I will put it there for safe keeping" - then forget where "there "is!!! I am not known for my tidiness when I have t shirts, displays, books, mugs, lumps of wood, keyrings, magazines, documents photos - the list goes on, all over the house! But I know it is THERE somewhere!
