The Godfather. Simply put, my favorite movie not involving outer space or general horror. I mean look at the cast, Marlon Brando, Al Pacino, Robert Duvall, Diane Keaton, Talia(Yo Adrian!) Shire. There is so much I can talk about, the acting, the story(based on Mario Puzo's best-selling novel). It's the rare perfect movie that can mix action, story, and acting.
If you do not know, the movie is based on ten years in the lives of the Corleone family, who are about to make their rise as the most powerful mafia family in the country. We see Vito's near-assasination and eventual death, Michael's doubts...
