Tunzelmann biog describes her as "a historian and writer", name checks her first book ("Indian Summer: The Secret History of the End of an Empire") and reveals that "she lives in London". Her Reel History articles have been coming out every Thursday since July last year, and are as entertaining as they are informative. Her drawing and quartering of Braveheart is a great example.
So far only two Bible films have been covered: Life of Brian (my posts on this film) and DeMille's The Ten Commandments (likewise). Hopefully, though, there will be plenty more to follow.
