If it is based on the Elizabeth Taylor book...
If the title page is to be believed then this is based on a novel by the English author Elizabeth Taylor. It was on my reading list in school but I never got round to reading it. Wish I had read it now! Although it might be a good thing I didn't, as I always compare films and their source material! Anyway, here's the outline of the book plot stolen from Amazon.co.uk:
It is the turn of the century and Angelica Deverell is fifteen years old. Her mother, a widow, keeps a grocery shop in a dreary provincial backstreet, working hard so that Angel can 'better herself'. The headstrong Angel, however, rejects her mother's sacrifice and retreats into a world of romantic dreams. Alone in her room, she plots her escape route, spinning fables at once extravagant and fanciful. To those around her this is simply folie de grandeur, but Angel knows better. She knows she is different, that she is destined to become a fˆted authoress, owner of great riches and of the mysterious Paradise House ... Highly diverting, this extraordinary novel charts the rise and fall of a popular novelist, and brilliantly evokes the life of Marie Corelli, the famous writer of romances. --This text refers to the Paperback edition.
Writing stories that are extravagant and fanciful, fifteen-year old Angel retreats to a world of romance, escaping the drabness of provincial life. She knows she is different, that she is destined to become a feted authoress, owner of great riches and of Paradise House ...After reading The Lady Irania, publishers Brace and Gilchrist are certain the novel will be a success, in spite of - and perhaps because of - its overblown style. But they are curious as to who could have written such a book: 'Some old lady, romanticising behind lace- curtains' ...'Angelica Deverell is too good a name to be true ...she might be an old man. It would be an amusing variation. You are expecting to meet Mary Anne Evans and in Walks George Eliot twirling his moustache.' So nothing can prepare them for the pale young woman who sits before them, with not a seed of irony or a grain of humour in her soul.
It sounds very interesting indeed. I love Ozon, of course, and the cast looks ace. Romola's great, so glad to see Lucy Russell as I thought she did a great job in "L'Anglaise & le Duc" and I've been wondering why I haven't seen her on the big screen and the wonderful Sam Neill and the goddess Charlotte Rampling and I'm not familiar with Michael Fassbender but on a shallow note he looks great and Ozon is a master of casting.
Of course, knowing the IMDB the info on the title page could be totally wrong!
