I had to watch this movie twice to understand all the nuances implied. Perhaps I was too young the first time because the movie beautifully explores all aspects of a relationship and how it falls apart. Better watch this than 500 Days of Summer.
Nothing out of the blue, but a nicely done tear-jerker (Isn't love in the time of war the biggest tear-jerking theme of all?) all the same. Reminds me why I love Audrey.
Possibly the most humorous fact: Audrey Tautou doesn't know how to skip stones; the stone-skipping scenes were made with special effects! Isn't it great to work on a movie with a huge budget? XD
