“Most famous” is just a teaser in the title. Let’s go with “best associated” or “likely to be remembered by” or longer phrases like that.
Best example I can think of, and trigger for the thread, is:
Brando as Stanley Kowalski in A Streetcar Named Desire: “Stella!”
Top that, if possible.
(With credit for the basic idea to the thread asking for one-line actors’ movies.)
Jack Benny’s “Rochester!”
Jimmy Durante’s “Good night, Mrs. Calabash, wherever you are!”
Khaaaaaaaannnnnnn!!
Until “Win Ben Stein’s Money”, he’d probably be most remembered for…
“Bueller… Bueller… Bueller…”
Stallone for “Yo, Adrian”
And/or “Beam me up, Scotty,” despite that exact line not actually having been said in the show.
Bond. James Bond.
Cary Grant: “Judy, Judy, Judy!”
It’s a topper because it’s his most famous line even though he never actually said it.
Even though he probably never really said it, Cary Grant’s most famous line is undoubtedly, “Judy, Judy, Judy!”
“My name is Indigo Montoya. You killed my father. Prepare to die.”
Brandon DeWilde: “Shane!”
Two that are famous but were never said:
“Elementary, my dear Watson.”
“Play it again, Sam.”
Along with: “He’s dead, Jim.”
Dustin Hoffman: “Mrs. Robinson.” (maybe not MOST famous, but definitely associated with.) And didn’t he scream out Ross’s character’s name at the end?
At the church behind the glass: ELAINE. And she shouts back “BEN” and all hell breaks lose.
Thanks. I need to see that movie again. It’s been decades.
That’s so sad; they all have to share their most famous line.
Seinfeld: “[Hello] Newman”
“Marcia, Marcia, Marcia!”–Eve Plumb
“Mary Hartman, Mary Hartman.” (Wouldn’t have thought of it on a bet, until your post. Thanks?)
