Parallels: Godfather Opening Scene and Shakespeare, Shylock's Complaint

I was clicking around Youtube waiting for a flight and by coincidence I re-watched the famous opening scene of The Godfather, and in the same half hour ran across an Orson Welles monolog from Merchant of Venice.   A few sentences nearly overlap.

Opening Scene of Godfather is here.    Camera opens on a black background and the head of a middle-aged Italian businessman.   His daughter has been assaulted, the boys got a suspended sentence, and he offers to pay Don Corleone to kill the boys.   Slowly, Marlon Brando rises and asks, This is the first time you come to me?  You never invite me into your home?   You are not my friend?   Now you insult me in this way, asking me to kill for money?

In a monolog from Merchant of Venice, which Welles performed in grand style on (wait for it) The Dean Martin Show, against a black background, nearly the same themes.   The Welles clip is here.   Welles opens by saying that Shakespeare wrote well on nearly everything, including the matter of bigotry.  We hear:

Signor Antonio, you’ve often insulted my money and my business practices in the Rialto. I have always just shrugged and put up with it because Jews are good at suffering. You called me a heathen, a dirty dog, and you spit on my Jewish clothes. And all because I use my own money to make a profit. And now it looks like you need my help. All right then. You come to me saying, “Shylock, we need money.” You say that!—even though you spat on my beard and kicked me like you’d kick a stray mutt out your front door. And now you’re asking for money. What can I tell you? 

Don Corleone:

We've known each other for many years but this is the first time you've come to me for counsel, for help.   I can't remember the last time you invited me to your house, for a cup of coffee.  But let's be frank here.  You never wanted my friendship.  You were afraid to be in my debt...I understand. You didn't need a friend like me.  But now you come to me, you say, Don Corleone, give me justice.  But you don't offer respect.   You come into my house, and you ask me to do murder, for money.  What have I ever done to make you treat me so disrespectfully?

Shakespeare quoted from a "Shakespeare in modern English" site.  Welles appeared on Dean Martin about 4 times 1967-1968.   Recall this was exactly the era of Selma (1965), Civil Rights Act, 1967 Detroit Riots.   Welles prefaced Shakespeare by strongly framing it as a pointed comment on bigotry.
