Casablanca is an excellent example of continuity editing, through the use of a multitude of editing techniques the film constantly places the characters and locations in time and space relative to each other seamlessly. While watching Casablanca I never had to ask myself questions like, how did we get here? Or where is this? Or when is what I’m seeing happening? All of this editing comes together to eliminate any possible distractions from the story or characters allowing you the viewer to stay fully invested in the love triangle and struggles unfolding around them. One shot shot in particular that doses a good job establishing where rick’s is in relation to Casablanca and more importantly the airport.
In this scene we see the front of Rick’s café as Rick brings his current girl out to send her home, right away in this scene we see a spot light cross the front of the building rhythmically a few times then it quickly cuts to a light house to orient Rick’s in the city.
As seen above the cut to the lighthouse.
Later in that same scene as Rick talks with the chief of police you see both of them look off camera toward the sound of an airplane.
