The murders are not so long but their expressions of horror on the victim's faces make it truly gruesome. Nudity and sex is a part of whole melodrama where the focus in on power, money and crime.

The movie The Godfather reflects about the gang wars, gruesome assassinations, killings and gun throbbing that happen in the real world. After all, it is a power game that causes one gang to fight against another to establish their supremacy and control over the business. It is so spontaneous that business rivalry turns into a personal revenge in no time among two criminally active gangs. Usually, a business stake is so much that one is out to finish other in the open gang wars circumventing state laws and regulations.
Marlon Brando has played a memorable character called The Godfather. Equally effective have been the roles played by Al Pacino of the youngest son Michael and James Caan playing for Vitos eldest son Sonny.
