"Plastics" is a good one, though it doesn't call back to every single scene in the entire story of a man's life like "Rosebud". I think you pretty much picked the cherry with Citizen Kane.

Dog Day Afternoon: "ATTICA!" Technically it's, "Attica! Attica! Attica!" But it is one word and it's a great moment. http://youtu.be/CYl9nNIoz8o

The ones that popped into my head are... "Inconceivable!" Vizzini, from The Princess Bride "No!" Caesar, from Rise of the Planet of the Apes. Love it for being the first word he says. "Abracadabra" Alfred Borden, from The Prestige. Love it for being the last word he says.

"Whoa" -- the matrix :)

"Miranda" from Serenity

Three thoughts, one already mentioned ("Inconceivable!"), the other two are names: "Khaaaaaaan!" and "Steeeeella!" From Wrath of Khan, clip (see very end) here and from Streetcar Named Desire, clip here Ends up Brando said "Hey, Steeeeella!", so that's two words :-)

Wings of Desire: "Compaņero" The Shining: "Redrum!"

ROCKY: "Adrian!" (Rocky) External=calling out to his wife Internal=success, accomplishment, a "thank you" to Adrian for sticking with him GHOST: "Ditto." (Molly) External=Molly loves Sam Internal=it is an "echo line" that Molly is repeating from earlier in the movie when Sam was alive and said ditto instead of "I love you, too", it takes on a more painful meaning now that they can't be together physically ...and on a MUCH less emotional level: FERRIS BUELLER'S DAY OFF: "Bueller?" (Economics Teacher) External: Ferris didn't show up for class Internal: Why is Ferris not here? (out of curiosity)I wonder what he is doing being that Ferris is so well liked and clever ANIMAL HOUSE: "Toga!" (Bluto) External: it's a toga party Internal: rebellion, encouraging everyone to release their primal urges/don't hold back/ have fun

See, I knew there were a lot of great one-word lines! In fact, at least three of them rank in the AFI top 100 lines of dialogue ever. You'll find out which ones this week each day with Daily Dialogue.

What would a "one word lines" Daily Dialog event be without a representative entry from Roger Corman... So with that, I present you all with... "ARROW-FEATHER!" http://www.youtube.com/watch?v=RWufdLk9k-s (one-word line is represented about 4 mins, 30 secs into clip) While never clearly defined in the running time of its source, "GAS-S-S-S-S: or It May Become Necessary To Destroy the World In Order To Save It," one can assume it is a verb and involves a man and a woman sans clothes, if you get my drift. Here are some notes on this preposterous relic of a film: http://www.webomatica.com/wordpress/2009/01/12/movie-notes-gas-s-s/ I, of course, don't expect you to use this example, Scott, but when I saw "one word lines," this is the first thing that popped into my head. Which, um, speaks unfortunate volumes about me. But hey, we can at least all groove on Country Joe and the Fish! ARROW FEATHER!!! (by the way, this "so bad it's kinda' good" film can be purchased on a double DVD with another 'youth in revolt' film called "Wild in the Streets." Every time I catch glimpses of the Wall Street sit-ins this week, I keep thinking of this type of flick...)

There is one word of audible dialog in Mel Brooks' Silent Movie: MARCEL MARCEAU: No! http://www.collegehumor.com/video/2936208/marcel-marceau

Bill, I had that on my own list: "Non!" Will have to include that as a bonus DD this week!

I'll also add a vote for "Inconceivable". Here's a video montage of Vizzini: http://www.youtube.com/watch?v=D58LpHBnvsI

Leon the Professional: "EVERYONE!" http://youtu.be/74BzSTQCl_c Rage, frustration, exhaustion, contempt, disbelief, and a touch of psychosis. Delivered flawlessly.

"WAR": said by Glen Close to John Malkovich in Dangerous Liaisons (1988). It's the climax of the film and summarizes the relationships between protagonist and antagonist, between MEN and WOMEN.
