Here’s something famous that Umberto Eco wrote about Casablanca:
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. … When all the archtypes burst in shamelessly, we reach Homeric depths. Two cliches make us laugh. A hundred cliches move us. For we sense dimly that the cliches are talking among themselves, and celebrating a reunion. Just as the height of pain may encounter sensual pleasure, and the height of perversion border on mystical energy, so too the height of banality allows us to catch a glimpse of the sublime. Something has spoken in place of the director. If nothing else, it is a phenomenon worthy of awe.
