“What smells purple?” --“The Man with the English”, Horace L. Gold
“We live in the lovely quiet and dark.” –The Persistence of Vision, John Varley
Ahem:
“Well, I’m Back” (Return of the King). JRR Tolkien wins the thread.
“I’m finished!”
Well, if we’re counting written work, there’s the last line of Alfred Bester’s “Adam and No Eve.”
And with glazing eyes, Steven Krane smiled up at the stars, stars that were sprinkled evenly across the sky. Stars that had not yet formed into the familiar constellations, and would not for another hundred million centuries.
Also, the final word from Fredric Brown’s “Nightmare in Yellow.”
“Surprise!”
In honor of Paul Newman:
Butch: When we get outside, when we get to the horses, just remember one thing. Hey, wait a minute!
Sundance: What?
Butch: You didn’t see Lefors out there, did ya?
Sundance: Lefors? No.
Butch: (confidently) Good. For a moment there, I thought we were in trouble.
Well, always look on the bright side of life…
A Matter of Oaths, from memory :
“But for now the learning was too late, and soon the fury of atoms in bondage conquered all.” - The Bully And The Crazy Boy
“She won’t live forever. But who does?”
“The circle had closed. She found what she had been searching for.”
- Contact, Carl Sagan.
The Ramans do everything in threes.
Which is an awesome last line…
…But, then we saw what the other three were, and wished they kind of did things in ones. Or did things in threes, but did them as good as the first one. But, really, we got four. So, now I’m confused. Damn you, Ramans! Damn you all to heck!
Pfff, a little biased, aren’t we?
But yeh, I almost posted that, but figured I’d leave it for you. 
“We each owe a death, there are no exceptions, I know that, but sometimes, oh God, the Green Mile is so long.” (King has a lot of good ones)
“I don’t know. Maybe it was Utah.”
Many, many different lead-ins, but they all ended with
“…the Twilight Zone.”
Hard to top Casablanca, of course, but some of my favorites
-The Masque of the Red Death
-The Usual Suspects
-Charlotte’s Web
-*The Diary of Anne Frank *(from the play. This wasn’t the last line of the actual diary, but she did write it.)
Crap. How could I have forgotten probably my favorite one form a movie??
“The Dude abides.”
“Home. I’ll go home. And I’ll think of some way to get him back. After all… tomorrow is another day.”
“Oh, good. For a moment there I thought we were in trouble.”
