Capturing Mary is a BBC television drama (co-produced by HBO), written and directed by Stephen Poliakoff, starring Dame Maggie Smith, David Walliams, Ruth Wilson and Danny Lee Wynter.

She recalls how Mr Graham's soirees were attended by the great and the good – the aristocracy, the nouveaux riche, industrialists, newspaper barons, editors, actors and directors.

We see Greville and the "young" Mary (Ruth Wilson) in Mr Graham's cellar selecting fine wines for a salad that he has prepared.

In the cellar, Greville tells Mary of dark secrets involving members of the British Establishment who are enjoying Mr Graham's soiree in the rooms above them.

Gemma Arterton, still in drama school at the time, played her first professional acting role as Greville White's young date, Liza.
