I have probably watched this movie a dozen times, and I delight in all the tiny, barely-acknowledged references throughout.

The Italian and French soldiers walking into the bar, and the Italian not able to get a word in edgewise.

The German couple saying, "Leibchen, what watch is it?" "Six watch" "Such watch" because that is the literal translation into English of the German "uhr".

The singing of "La Marseillaise" by extras who were mostly themselves refugees from Nazi-occupied Europe -- the emotion was real.

I've heard a lot of stories in my time. They went along with the sound of a tinny piano playing in the parlor downstairs. "Mister, I met a man once when I was a kid," it always began. (Rick is calling Ilsa a whore.)

Every scene is a gem.
