One of the favourite movies of my wife, and one that I am reminded of every day when I check the activity on my Flickr account. My photograph with the same title (incidentally one of my own favourites from my stream) gets a few views every day from people googling for this movie title. As a matter of fact, image googling for "In the mood for love" yields my photograph already at page 2. Wonderfully atmospheric poster as well.
More on this movie in the IMDB article linked to below.
