Some good responses here, but @stanleybmanly, I’m going to disagree with you on the “most popular quotes” claim.
I think Casablanca has WoO beat all hollow on quotable lines:
“Of all the gin joints, in all the towns, in all the world, she walks into mine.”
“We’ll always have Paris.”
“I’m shocked! – shocked, I tell you! – to learn that there’s gambling going on in this establishment!”
“Play it, Sam.”
“Who are you really, and what were you before?”
“If that plane leaves the ground and you’re not with him, you’ll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.”
“I’m no good at being noble, but it doesn’t take much to see that the problems of three little people don’t amount to a hill of beans in this crazy world.”
“Round up the usual suspects.”
“I think this is the start of a beautiful friendship.”
“Here’s looking at you, kid.”
Oz has some memorable quotes, but its quotes don’t have that kind of currency.
