While many fans and scholars debate as to what the Great American Novel is, it should be no question as to what the Great American Film is. The obvious answer: Citizen Kane. Many people will ask what is it about Citizen Kane that makes it so great. Well, it's a combination of several things. One, it has a fantastic script. Two, it has the greatest ensemble of actors ever. And three, it is told by Orson Welles, the greatest storyteller ever, with the exception of maybe Walt Disney.
