Scorsese made a classic mafia film with classical mafia film actors such as Al Pacino, Robert de Niro and Joe Pesci.
Robert de Niro is the man from the title, a small time man who works himself up in the mafia ranks. Pacino is great at the overheated head of the truckers union and became one of the most powerful men in the USA.
The Italians in the USA have their hands in many businesses, often illegal. When the Kennedys rise to power, they start to get opposition, but fortunately that problem solves itself. Then internal problems occur that need to be taken care off.
“The Irishman” is an alright mafia film that in my opinion needed not to last for three-and-a-half hours. I must say that De Niro does not really convince.
