Sunset Blvd. could be looked at as a thesis on what fame does to certain people. For Norma Desmond, fame created a fantasy world that forever trapped her. Living alone in that giant house on Sunset, save for her servant Max, Norma whiles away the hours planning her magnificent return. Her fame kept alive by fan letters, and her hope of return kindled by Joe Gillis. For Norma, there is no other life than standing before cameras and acting out lives of characters that are larger than life. Of course, no one knows who Norma Desmond is. Gloria Swanson gives a magnificent performance. She runs from melancholy, to unbridled joy, to complete mental breakdown. William Holden is the ultimate cynic. He plays Norma like a fiddle but gets ensnared in her web of decaying glory. In the end, Joe pays the price for enduring Norma's insanity. As she descends that staircase in the final scene, you can see that she is completely lost in her own world. A world where no one grows old, where she is forever young, and where she is the greatest star of them all. After all, stars never age.
