Resurrecting this to say that at present the cast stands at:
Jean Valjean - Hugh Jackman
Inspector Javert - Russell Crowe
Madame Thenardier - Helena Bonham Carter
Jackman apparently wants Anne Hathaway for Fantine, and supposedly Hooper wants Geoffrey Rush for Thenardier.
My best friend is very upset with the casting. She absolutely adores Russell Crowe (and has seen and owns every movie he has been in) but she hates Hugh Jackman and refuses to watch any movie he is in.
