Jack Nicholson is a great actor. No, not a great actor, a spectacular actor. This is a film from fairly early in his career, as well as it is for several other actors in this film, who later have had long, great careers too, including Danny DeVito, Christopher Lloyd and Brad Dourif. The film has some unforgettable moments... who could forget Louise Fletcher's icy stare, Jack Nicholson's smart-aleck remarks or Will Sampson's impressive, almost entirely silent performance? The film portrays the horrible truth about how patients were treated in mental institutions back then, and tells the story of someone who desperately wanted to break out, to rebel, to change things, for himself and for the others. I was compelled by this film, from the very first frame. I never took my eyes off it, and I will definitely be thinking about this film for a while. I thought it was great the way one of the very first frames depicted the institution as something far more similar to a prison than a hospital. Milos Forman did a great job of making that contrast very powerful to the viewer. The film is very moving and a truly beautiful cinematic experience. Every single actor gives a stellar performance, every single character is perfectly written, every single line, every single frame is absolutely perfect. I wouldn't change a thing in this film. It has a great pace, you never lose interest, but it never seems to be rushing to get through it, either. It's simply perfect. I have not read the original book, but if I ever come across it, I might check it out. I have only seen this film once, but I will definitely watch it many times in years to come. I recommend this amazing piece of great cinema to anyone who has at least a slight interest in the drama genre, or any fan of any of the actors, as they are all in their absolute prime in this film. 10/10
