Besides being a 'woman in peril in her house' film

Midnight Lace also fits into a genre of posh England after World War II. I love the atmosphere, the environment. Can you think of others besides these - set between 1945 and 1965?

The Paradine Case
The Reluctant Debutante
Witness for the Prosecution (though only slightly)
The Grass is Greener
The Miniver Story
Royal Wedding (somewhat - in the Lawford story)
The Yellow Rolls-Royce (in the Rex Harrison-Jeanne Moreau story)

Usually such films were set in earlier periods- even much of Terence Rattigan and Noel Coward - Waugh's Brideshead Revisited - are deliberately set pre-War, even if written much later.

And of course films like My Fair Lady, Room with a View, The Golden Bowl, Howard's End - were written - and are performed - in the Edwardian era.
