5. 'The Godfather: Part II': Celebrating the Movie's 40th Anniversary With 8 Little-Known Facts

It has been 40 years since Francis Ford Coppola’s “The Godfather: Part II” was released on Dec. 20, 1974 and the movie has had a lasting impact.

“Part II" was released two years after the “The Godfather: Part I” and it is widely considered the best sequel of all time. To some, the sequel even surpasses the original. “The Godfather: Part III” would come in 1990, but the third time was not quite the charm.

The sequel focused on Michael Corleone, played by Al Pacino, as he attempted to expand his family business into a then-brand new playground called Las Vegas. The film included flashbacks to the early 1900s, showing the rise to power of a young Vito Corleone, played by a little-known actor named Robert De Niro. In Part I, the Vito Corleone character was played by the iconic Marlon Brando.
