Wait, The Godfather was Based on a Book?

I'm just kidding with that title, but it's pretty clear that the majority of people who have encountered the Godfather in the past forty years have encountered it as a film first. I finally sat down to read the novel and compare it to the two fine films. Coppola, Francis Ford. The Godfather. Paramount Pictures: USA, 1972.Coppola, Francis Ford, The Godfather Part II. Paramount Pictures: USA, 1974.Puzo, Mario. The Godfather. Signet: New York, 1999. "The Godfather Waltz" composed by Nino Rota
