Jew speaking to Gentile

Characters:

The angry verbally abusive one is the Jewish movie producer Jack Woltz. He is played by John Marley (born Mortimer Leon Marlieb) Marley was born in Harlem in New York City to Russian-Jewish immigrant parents.

The polite collected one is the Mafia attorney German-Irish Tom Hagen. He is played by Robert Selden Duvall Duvall who was born January 5, 1931, in San Diego, California. Duvall was raised in the Christian Science religion and has stated that, while it is his belief, he does not attend church.

My question, what is with the shouting and threats, the violence and wildness of the Jewish guy?
