Francis Ford Coppola: Director of The Godfather
Coppola directed my favorite movie of all time and what critics believe is one of the greatest movies every made.  He had the vision for the entire movie, with every detail building an amazing movie.  The acting, lead by Coppola, was stellar, and without a great leader/director, a movie will never live up to its full potential.  Coppola will go down in history as one of the greatest directors to ever live.
