Kay: It made me think of what you once told me: "In five years the Corleone family will be completely legitimate." That was seven years ago.
Michael Corleone: I know. I'm trying, darling.

[While watching a "Punch and Judy" puppet show.]
Don Fanucci: Oh, this is too violent for me!

Al Neri: Our friend and associate Hyman Roth is in the news. The High Court of Israel turned down his request to live there as a returning Jew. He landed in Brazil last night offering a "gift" of a million dollars if they'd let him stay. They said no. His passport's been invalidated, except for his return trip to the States.
Tom Hagen: He'll try Panama next.
Michael Corleone: Panama won't take him. Not for a million, not for ten million.

Michael Corleone: I don't feel I have to wipe everybody out, Tom. Just my enemies.

[Michael confronts Fredo after learning he betrayed him.]
Michael Corleone: I know it was you Fredo. You broke my heart. You broke my heart. You broke my heart.

Michael Corleone: There are many things my father taught me here in this room. He taught me: keep your friends close, but your enemies closer.

Vito Corleone: I make him an offer he don't refuse.

Michael Corleone: I'll change; I'll change. I've learned that I have the strength to change.

Hyman Roth: We're bigger than U. S. Steel!

Hyman Roth: Stupid thugs. People behaving like that with guns.

Michael Corleone: If anything in this life is certain, if history has taught us anything, it is that you can kill anyone.

[About the unrest in Cuba.]
Michael Corleone: I saw a strange thing today. Some rebels were being arrested. One of them pulled the pin on a grenade. He took himself and the captain of the command with him. Now, soldiers are paid to fight; the rebels aren't.
Hyman Roth: What does that tell you?
Michael Corleone: It means they could win.

Michael Corleone: Hyman Roth has been dying from the same heart attack for the last twenty years.

Fredo Corleone: I'm your older brother, Mike, and I was stepped over!
Michael Corleone: That's the way Pop wanted it.
Fredo Corleone: It ain't the way I wanted it! I can handle things! I'm smart! Not like everybody says... like dumb... I'm smart and I want respect!

Michael Corleone: Fredo, you're nothing to me now. You're not a brother, you're not a friend. I don't want to know you or what you do. I don't want to see you at the hotels, I don't want you near my house. When you see our mother, I want to know a day in advance, so I won't be there. You understand?

[Ordering drinks in a Havana cafe.]
Fredo Corleone: Uno... por favor...
[to Michael]
Fredo Corleone: How do you say "banana daiquiri"?
Michael Corleone: "Banana daiquiri."

Fredo Corleone: Every time I put my line in the water I said a Hail Mary, and every time I said a Hail Mary I caught a fish.

Senator Pat Geary: I despise the way you pose yourself. You and your whole fucking family.
Michael Corleone: Senator we are part of the same hypocrisy, but never think it has anything to do with my family
