Let me explain something to you. Um, I am not “Mr. Lebowski”. You’re Mr. Lebowski. I’m the Dude. So that’s what you call me. You know, that or, uh, His Dudeness, or uh, Duder, or El Duderino if you’re not into the whole brevity thing.
How can you mention Mae West and not cite her most famous line?
“Beulah, Peel me a grape.”
Also…
coatcheck girl: Goodness, that’s a fine mink coat you’re wearing!
Mae: Goodness had nothing to do with it.
Cary Grant: I’ve heard a lot about you.
Mae: Yeah, but you can’t prove any of it.
Mae: How tall are you without your horse?
Actor: Six foot, seven inches.
Mae: Never mind the six feet. Let’s talk about the seven inches!
My favorite Gene Wilder lines are from Silver Streak. I don’t think of them as “iconic movie lines,” though.
Yeah–so far, nothing offered by Gene Wilder strikes me as an iconic movie line. Some very funny, well-delivered lines, to be sure, but not lines that get referenced, riffed off of, turned into cliches, etc.
It’s tough, I think, to meet the parameters laid out by the OP. If you quote a line “cold”, and people still know who said it (if not the exact movie itself), then does it qualify as an iconic line, or is it merely a memorable line form a movie?
“I won’t be wronged. I won’t be insulted. I won’t be laid a-hand on. I don’t do these things to other people, and I require the same from them.”
“Fill yore hands, you sonuvabitch!”
The Wikipedia article about the AFI list suggests criteria:
Hmm. I guess I need more coffee today.
While I might have cause to use “what knockers!” and “You are talking about the nonsensical ravings of a lunatic mind!” in real life situations, I won’t be saying “Do ya feel lucky, punk?” or “Fill yore hands…”.
Is the linked definition suggesting Gene Wilder is a bigger contributor to the iconic culture than the action hero movie stars?
Or B), mlees has a thick skull, and just being able to conjure up and reminice about a film by quoting one line is sufficient for iconic status?
May I suggest: the winner is doubtless on this page. Especially Item #2.
How’s that for “iconic”?
Note this line: “circulating through popular culture, they become part of the national lexicon.”
“Do ya feel lucky, punk?” is part of the national lexicon. “What knockers” is not. I can imagine an advertisement for, say, an XTREME soft-drink referencing the former, but not any advertisement, however edgy, referencing the second, because the second line just isn’t sufficiently well-known.
A silly cartoon series might have a character shout, “Rakes! Why’d it have to be rakes!” (for a terrible lame example): they’d rely on sufficient viewers’ instant familiarity with the original line. They wouldn’t have a character say, “I know,” hoping viewers would instantly flash to Harrison Ford’s delivery of that line.
Edit: I think the line needs to have some legs beyond just referencing the film. Ford’s line about snakes is a wry expression of phobia, and if a friend were terrified of spiders and shouted, “Spiders! Why’d it have to be spiders?” I’d know what she meant. She’d be talking about her own phobia while making a wry movie allusion.
“We’ll always have Paris” could similarly be used. Someone leaving a job after a long while could say, “We’ll always have EOGs” wistfully to co-workers, mocking the bittersweet occasion of leaving a job.
Ok, that helps. Thanks!
Don’t forget “HOOAH!”
But Clint Eastwood would be my favorite for iconic lines.
Arnold lines that should be on the list:
Get to the chopper!
No problemo.
Milk is for babies. When you grow up you have to drink beer.
These lines are mildly funny. Do you really think they are iconic?
Please define what constitutes an iconic line and explain why this line is iconic:
*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. *
and this in isn’t:
Get to the chopper!
Thanks.
FYI:
Ah, more Jeff Bridges 
Because most people know the first one. I knew it years before I even knew what Casablanca was just from seeing it get parodied or hearing it quoted. I still don’t know what “Get to the chopper” is from, and I’ve never heard anyone quote it or parody it.
Then you should click the link I included in the post you just quoted.
And I would bet “most people” don’t know the former and that more are familiar with
the latter.
I agree. I’ve seen Predator and I don’t recall the “get to the chopper” line from it.
But that Casablanca quote isn’t just well known–it’s a part of the culture. People parody it, quote it, etc. How often in pop culture do you hear someone mention the chopper quote versus how often is Casablanca (and that particular quote) referenced?
I’m familiar with other lines from Casablanca but not that one and I don’t recall it being parodied. I’ve heard the chopper quote used and parodied plenty. Did you click the link? It’s very much a part of the culture.
