Film One of the key locations in Glorious 39 is Walsingham Abbey in Norfolk. Here's a contemporary local news clip which talks about the making of the film. The Glorious 39 piece begins two minutes in (after a piece about another country house which is going through just the sort of stresses that might themselves have appeared in a Stephen Poliakoff tv series):
As the expert in the clip describes, one of the key shots in the film is in the opening sequences as DP Danny Cohen's steadicam swoops through the medieval abbey, its giant incongruous, breathtaking arches standing impenetrably against the newer house. Like that house, Glorious is a newer addition to the landscape of a family which has existed for many year but, which like the abbey, is apparently standing firm but crumbling.
