props in Casablanca are mainly glasses of expensive alcohol, and a lot of money. mainly the sheets of paper with the boarding passes on them for people to leave. and during the movie there is loads of people smoking cigarettes, through out the whole movie they always had one in their hand.
the costumes in Casablanca are very 1940s and all the women wear nice long skirts with a hat, the men were always wearing suits to show their wealth.
sets in casablanca are in always fancy bars or in posh looking houses in nice town and clean streets, they use alot of nice areas that are large and have a rich type of vibe to it.
