I love that movie. Good performances all around.
It has some of my favorite dialogue ever. The scene where William Holden is packing and arguing with Faye Dunaway is fantastic. I seem to remember him calling her life a 'screaming void'. Such a great scene.
The Beale character is wonderful. To me, he and his rantings embody exactly what's missing from both TV and American culture in general--passion and intelligence. And his message is as disruptive as it was when the film was made. His speeches are just energizing, but the pity is that people like Beale aren't revered in real life.
