I have recently watched both the Duchess staring Kiera Knightley, and Changeling staring Angelina Jolie. Both movies were based on true stories of two very different, yet very similar women. The Duchess is based on the life of Georgiana Cavendish, born in 1757, and though a very long movie, it was extremely captivating and emotional. The same could be said about Changeling, based on the story of Christine Johnson in 1928. It actually carried two of the same themes as the first movie: of motherhood, and the role of women in history.
I highly recommend either movie-both tearjerkers, which will stay in your mind for a long time after the viewing.
