Two of the stars didn't want to be in the movie, and no one knew how the picture would end until they shot the final scene. Yet, out of the chaos came one of the most enduring films of all-time, Casablanca! At every step along the road to Casablanca, the picture's creators had to make choices that later meant the differences between triumph and failure. Initially, Ronald Reagan was announced as the lead, but Bogart saw the film as a great opportunity, and was very sure of himself...never worried -- and nobody at the time realized they were making one of the all-time great Hollywood films. And what a movie it is! Adventure, an exotic locale, a memorable song, a beautiful heroine, a masculine hero, and an evil villain. Casablanca has it all. It is no wonder why people watch this film again and again.
