The Film That Shouldn't Have Worked — But Did
By all accounts, Casablanca (1942) should not be the masterpiece it is. The screenplay was being rewritten as shooting progressed. The ending was undecided until late in production. The film was churned out as a wartime propaganda piece by a studio system that produced dozens of pictures a year. And yet, somehow, everything clicked — and the result is one of the most perfectly constructed films ever made.
The Story, Simply Put
Rick Blaine (Humphrey Bogart) runs a café in Casablanca during World War II — a neutral city crowded with refugees seeking exit visas to escape Nazi-occupied Europe. When his former lover Ilsa Lund (Ingrid Bergman) arrives with her husband, Czech resistance leader Victor Laszlo, Rick must choose between his personal heartbreak and a larger moral duty. It sounds simple. It is anything but.
What Makes It Endure
The Writing
The screenplay, credited to Julius and Philip Epstein and Howard Koch, is a clinic in efficient, expressive dialogue. Lines that sound like clichés today were invented here: "Here's looking at you, kid." "Of all the gin joints in all the towns in all the world, she walks into mine." These aren't accidents — they're the product of writers who understood that the most memorable lines feel like they were always there, waiting to be said.
The Performances
Bogart had been playing gangsters and heavies for years before Casablanca. Here he found his defining persona — the cynical idealist, the man who pretends not to care but cares more than anyone. Bergman, meanwhile, brings a luminous ambiguity to Ilsa: we never quite know where her heart truly lies, and that uncertainty is essential to the film's power.
The Context
Released just weeks after the Allied invasion of North Africa, Casablanca spoke directly to audiences living through the war — to the genuine moral stakes of choosing sides, the cost of exile, and the weight of sacrifice. That historical specificity, paradoxically, is what gives the film its universal resonance. The emotions it captures are not dated. They are permanent.
The Ending: A Master Class in Restraint
The film's final scene — Rick sending Ilsa away on the plane, the famous airport fog — is perhaps the most analysed ending in cinema. What makes it extraordinary is what is not said. The sacrifice is total, and it is performed with almost no melodrama. Bogart underplays it completely. That restraint costs more than any tears would.
How to Watch It Today
If you've never seen Casablanca, approach it without irony. Resist the temptation to treat it as an artefact. Watch it as the people of 1942 watched it — as a story about love, war, and what we owe each other in the worst of times. You will find it hits harder than you expect.
Casablanca is available on most major streaming platforms and in regular theatrical re-releases. Watch it on the biggest screen you can find.
