Thanks to Snaps, while browsing through the movie channels the other day I stumbled upon Atonement and recalled his recommendation, so I recorded it and watched it last night. 
What a good film. The use of flashbacks and flashforwards gave incidents the perspective of a number of different characters and added a lot of real depth to the storyline. A gripping, sad, period piece as only the Poms seem able to do so well. The best thing Keira Knightly has done since Pride and Prejudice, (also directed by Joe Wright).
(I must also confess to a less than pure interest when Keira climbed out of the water.
