It was really interesting to see the costumes of the period, particularly those of high class women and the different military uniforms. The city of Casablanca has an interesting mix of people. Some of the details about the letters of transit and the role of the Germans get a bit confusing, but I'm sure it would be more clear in a second watch.
There is a scene of drinking in the dark with at the piano that is beautifully shot, The light s coming in from, the ,moving spotlight and the smoke of his cigarette is illuminated in a subtle way, and his face is mostly in shadow. It reflects his somber reflection in a really artistic way. Humphrey Bogart does an excellent job in balancing the stoic demeanor Rick puts on to the moments where we see past the façade into his heartache.
