(on Katharine Hepburn) She talks at you as though you were a microphone; she lectured the hell out of me on temperance and the evils of drink. She doesn't give a damn how she looks. I don't think she tries to be a character. I think she is one.

Capt. Renault: What on Earth brought you to Casablanca? Rick Blaine: My health, I came to Casablanca for the waters. Capt. Renault: The waters? What waters? We're in the desert! Rick Blaine: I was misinformed.

I hate funerals. They aren't for the guy who's dead. They're for the guys who are left alive and enjoy mourning.

Making money isn't the main point of business. Money is a by-product.... A new product has been found, something of use to the world. A new industry moves into an undeveloped area. Factories go up, machines go in and you're in business. It's coincidental that people who've never seen a dime now have a dollar and barefooted kids wear shoes and have their faces washed. What's wrong with an urge that gives people libraries, hospitals, baseball diamonds and movies on a Saturday night?

The only point in making money is, you can tell some big shot where to go.
