I used to be Snow White but I drifted.
Between two evils, I generally like to pick the one I’ve never tried before.
Its not the men in your life that matters, its the life in your men.
And one that is not often quoted but should be: I feel like a million tonight. But one at a time.
Absolutely- and even without*** Casablanca***, Bogie would be a contender.
“I won’t play the sap for you.”
“Pardon me, but could you help out a fellow American who’s down on his luck?” (If you get quoted in Bugs Bunny cartoons, it’s an iconic line!)
“Ah, but the strawberries! That’s where I had them!”
“I kid you not.”
"I hope they don’t hang you, precious, by that sweet neck. Yes, angel, I’m gonna send you over. The chances are you’ll get off with life. That means if you’re a good girl, you’ll be out in 20 years. I’ll be waiting for you. If they hang you, I’ll always remember you. "
I think Jack Nicholson would be up there
“Here’s Johnny!”
“You can’t handle the truth!”
“You make me want to be a better man.”
“Do you think God knew what he was doing when he created woman?”
McMurphy: "I’m a goddamn marvel of modern science. "
“Wait’ll they get a load of me”
many more!
Either I don’t know nearly as much about movies as I thought I did (and I already didn’t think I knew much about movies), or other folks have a much lower standard for “iconic” than I do.
“I want you to hold it between your knees.”
+1
I’ve recognized about a third of the lines quoted. And even for some of those lines from there I’ve never heard used or referenced/imitated elsewhere. And then even those are usually badly misquoted.
But after taking a second look, it looks like the board through repetition is coming to the 3 person conclusion I did.
AFI seems to agree with Bogart as the answer. He has 5 quotes on their “100 years of movies” movie quotes list. 4 are from Casablanca, with “The stuff that dreams are made of” from The Maltese Falcon added.
The next highest count is 3 for Pacino, Bette Davis, Brando, Tom Hanks, and Vivien Leigh.
Really, now.
It’s actually: “… you’ve got to ask yourself one question: ‘Do I feel lucky?’ - Well do ya, punk?”

“Such ingratitude - after all the times I saved your life.”
See you at the party, Richter.

“My grandfather’s work was Doo-Doo!” <stabs scapel into thigh> Young Frankenstien
What did you expect? “Welcome, sonny”? “Make yourself at home”? “Marry my daughter”? You’ve got to remember that these are just simple farmers. These are people of the land. The common clay of the new West. You know… morons. Blazing Saddles
I want everything I’ve ever seen in the movies! The Producers
She was a bad egg Willy Wonka and the Chocolate Factory
Eastwood, like Schwartzenegger, will always do well in this due to the amount of roles each has played where they speak relatively little dialogue, but most of it is memorable.
Pacino also needs to be up there, and I’ll add “Attica! Attica! Attica!” to the memorable lines.
Uh, those were all iconic, not non-iconic.
For me, it’s Harrison Ford, because he was lucky enough to be both Han Solo and Indiana Jones, two of the coolest characters in movies.
“Never tell me the odds.”
Oh that was funny. Kevin Pollock does a funny Walken skit…cause they’re fast.
My mind is a blank right now for another example of this sort of actor. Maybe Paul Newman?
Jeff Bridges.

“Oh I’m sorry, just one moment. Is this a five minute argument or the full half hour?”
“My hovercraft – is full of eels.”
“She turned me into a newt! I got better…”
“But, then, the African swallow’s not migratory…”
How about Sigourney Weaver?
Aliens: “Get away from her, you bitch!” And the one about nuking it from orbit.
Ghostbusters: “Do you want this body?”
Galaxy Quest: “Look, I have ONE job on this lousy ship. It’s STUPID, but I’m gonna do it, OKAY?”
Wow, no one yet with:
Frankly my dear, I don’t give a damn.
