Oh I thought he was the future king George VI too. Thanks for clarifying.
They really jammed in as many refs to the 1930s as they possibly could, didn't they? Someone down from t'pits for the depression, a refugee Jew from Germany, a nazi ambassador, the abdication, Moseley, Cecil Beaton, the end of the Raj. I was just waiting for the Mitfords to come tripping into a cocktail party. Or perhaps Al Jolson.
And as a result the plot seemed v trite, whisking all the characters in and out with unseemly haste. Here's Rachel from Germany - oh she's dead; here's Johnny from Yorkshire - oops he's in borstal; here's a fascist - oh he's seen the error of his ways; here's another fascist - oh she's off to Berlin with the ambassador. 
And. As. For. The. Childbirth. Scene.
I quite liked the Hudson and Mrs Bridges replacements though. Anne Reid is always good for a laugh.
