sets (interiors)

sets are used as a story telling device in Casablanca, we can see this with Ricks bar, as it is used to show a place where people find solitude, can make deals, and distract themself from their troubles.

another set that is used as a story telling device is the train station as the rain shows rick’s heartbreak and allows us to sympathize with him having to leave the person he loves.

locations:

the location of the town in the opening scene shows what kind of place Casablanca is and what it is like to be there

the location of the airport is used to show that the end is near, and that the film is ending, also showing us how rick has changed as now he is staying and ingrid is leaving, contrasting the train station scene where he leaves and ingrid stays

costumes:

costumes are used as a story telling device as it tells us about a character, we see this with  Major Strasser as he is always wearing his badges and is always in uniform while on screen, showing how he is a prideful person.

we see this with rick’s costume aswell, as he wears a white tuxedo in the film, white usually being a colour to show purity, showing that despite his cynical shell, inside he is a sympathetic person.
