Now, before you object, a clarification is in order. Casablanca, an enduring classic released in 1942, is perfect in and of itself. It doesn't need any adornments. The love story, set against a backdrop of war, it's one of the most romantic in cinema history. So a sequel would not need to pick up where the film left off. The noble decision made by Ingrid Bergman's Isla Lund to leave Humphrey Bogart's Rick Blaine should remain untouched to preserve the gorgeous melancholy of the movie's final scene. But why not pick up some time in the future and feature a piecing together of the characters' histories by their grandchildren? It would be worth it if only to ensure another generation would be exposed to the original film.
