When they were gearing up to release "The Godfather Part III," there was a fair amount of talk about quickly turning around and making a "Godfather Part IV" with Andy Garcia as the star.  Once people saw "The Godfather Part III," that talk pretty much stopped, but over the years, they talked about various casting configurations.  At one point, I remember hearing Leonardo Di Caprio's name in the mix, and for people to get excited about a new entry in this series, it would have to involve some exciting names and a truly great first trailer.  But admit it… you'd be curious to see what happened with the Corelones as they moved into the modern age.
