Atonement

I thought I had read Ian McEwan's Atonement sometime in the early 2000s. If I had, my forgetfulness is fabulous. I didn't remember even a wee bit of the story when I saw this movie based on the book except for one certain fact,that it was set in England. Anyway, the movie has an interesting plot and successful casting of actors including Keira Knightley, James McAvoy and three who plays various stages of the character - Briony Tallis(Saoirse Ronan, Ramola Garai and Vanessa Redgrave.) The movie is presented mostly thru' the eyes of Briony. That way it could be labeled as a coming of age movie. It is an emotional triangle involving two siblings and outsider which takes place before,during and after WW2.
