costume:

Rick is always seen wearing a white suit. This shows signs of class and is also classic attire of the 1940s. the fact that he’s is the only person wearing white outlines him as the main character

in Casablanca Capitan Renaldas is seen wearing his army uniform with his medals on show. this is because he is proud of his achievements

props:

this is a plane in the 1940s. you can see that the plane is smaller and looks more rickety. it has propellers instead of engines as they were not invented yet

in the film the actors are mostly all smoking. this is because in this time it was normal to smoke inside and wasnt frowned upon

locations:

sets:

sets can be used to give us information about the film that is not said or given. for example the weather at the runway shows us that rick is sad Lisa is leaving and that it will be a dangerous journey
