Much has been made of the bizarrely efficient disorganization that uniquely helped some of the picture’s greatest moments retain their historic place. No matter how accomplished the scholar or enthusiast examining the picture, none of them pinpoint exactly why the film turned out so well, if in fact there is any reasoning behind it besides pure luck. [If anything,] too much emphasis is placed on the details of the sordid production history, which inevitably and unfortunately becomes the centerpiece in discussions about Casablanca. These stories lend an interesting background, but hardly reveal anything essential about why the end result has earned its iconic status.

The film has a peculiar magic to it, and because of its pace the richness of its sense of detail often goes unnoticed. Audiences make generalizations about Casablanca because of how all those little particulars add up. Film lovers discuss it with a starry look in their eyes, as if they were describing their first kiss or a lost love, because something in the film touches them, perhaps its theme of dignity and decency, of rediscovered idealism. Men seem almost instinctively drawn to Humphrey Bogart’s Rick because he’s a man of integrity, while women seem to dig him because he’s a man of mystery.

[Precisely] because all the archetypes are here, precisely because Casablanca cites countless other films, and each actor repeats a part played on other occasions, the resonance of intertextuality plays upon the spectator. [Thus] Casablanca is not just one film. It is many films, an anthology. Made haphazardly, it probably made itself, if not actually against the will of its authors and actors, then at least beyond their control. And this is the reason it works, in spite of aesthetic theories and theories of film making.
