Casablanca is going to rule this list. Here are some of the top quotes:
"Frankly my dear, I don't give a damn."
"I'm make 'em an offer he can't refuse."
"You lookin' at me?"
"I couldda had class. I couldda been a contender."
"Here's looking at you kid."
"Of all the gin joints in all the towns in all the world, she walks into mine."
"Do you feel lucky? Well, do you, punk?"
"Play it once Sam. For old time's sake."
"I love the smell of napalm in the morning."
Isn't there a Clink Eastwood line where he brandishes a pistol and says: "Looky what I got."
