The Godfather1972

Johnny Fontane:
A month ago, he [Woltz] bought the movie rights to this book, a best-seller, and the main character, it's a guy just like me. I, uh, I wouldn't even have to act, just be myself. [choking up] Oh, Godfather, I don't know what to do. I don't know what to do.

Vito:
[shaking Johnny] You can act like a man! [He slaps Johnny.] What's the matter with you? Is this how you turned out, a Hollywood finocchio that cries like a woman? "Eheheh! What can I do? What can I do?" What is that nonsense? Ridiculous. You spend time with your family?

Johnny:
Sure I do.

Vito:
Good, because a man who doesn't spend time with his family can never be a real man. Come here. You look terrible. I want you to eat. I want you to rest a while, and in a month from now, this Hollywood bigshot's gonna give you what you want.

Johnny:
It's too late, they start shooting in a week.

Vito:
I'm gonna make him an offer he can't refuse. Now, you just go outside and enjoy yourself, and, uh, forget about all this nonsense. I want you, I want you to leave it all to me. The line in bold is ranked #2 in American Film Institute's list of the top 100 movie quotations.
