[MRM]

I liked the movie and the ending hadn't really made an impression on me one way or another until seeing it mentioned here. I watched it a couple of times and think I like it. I listened closely and came up with dialog that I thought was perfect for the scene and to end the movie. Then I searched a little and found that through the magic of the internet, someone did convincingly figure out what Bill said. It was exquisitely eloquent. You can search if you want, but you may be more satisfied with your own interpretation, which was the point. Whatever the truth of the dialog is, her response showed they still shared the secret connection they forged in Tokyo. Which is the real meaning of the movie - a true, deep human connection transcends the environment where it was forged.

Apparently both Murray's dialog and the final kiss were improvised.
