With a historical novel you know that liberties are being taken. Since Walter Scott, we know that poetic license, dramatic license, that events been conflated and that liberties have been taken, characters ditto, dates rearranged. But people don't seem to understand that movies are fictions, they are dramatizations, at least historical movies, and we should accord the moviemakers some of the same understanding and latitude. When you go to a movie you know it's a dramatization and not history.
