The Movie: The Godfather (1972)

The Lines: "Luca Brasi held a gun to his head, and my father assured the bandleader, that either his signature or his brains would be on the contract."

"It's not personal, Sonny. It's strictly business."

"I'll make him an offer he can't refuse."

"Don't ask me about my business, Kay."

The Godfather, Al Pacino, 1972.
