PLAYING IT OVER AND OVER AGAIN: How Casablanca was made.
Although I’m not sure I trust a journalist cynical enough to consider Casablanca to be “camp.” As Roger Ebert wrote when the film turned 50:
This is a movie that has transcended the ordinary categories. It has outlived the Bogart cult, survived the revival circuit, shrugged off those who would deface it with colorization, leaped across time to win audiences who were born decades after it was made. Sooner or later, usually before they are 21, everyone sees “Casablanca.” And then it becomes their favorite movie.
It is The Movie.
Indeed.™
