Query: Piss On Your Rules Nurse Ratched!

One of the Greatest Films of All Time. Jack Nicholson in his greatess role he ever played. What is strange is that my uncle plays in the film, and I am playing in a school play as McMurphy. I saw this film at 3 Am. in the morning and did not bother to turn it off. It is so powerful that I could not believe there is such a story. The Greatest cast I have ever seen in a motion picture. This is the greatest cast of all time. Jack Nicholson, Christopher Llyod, Danny Devito, Brad Dourif, etc....Every line is an excellent quote. Every scenes is awesome. I will not tell you the story, but I will tell you this- Buy IT!!!!!!!!!!!!!!! Ranked in the Top 20s of the Greatest 100 Movies of All Time by AFI!
