Perfect last lines.

Book, not movie.

“The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which.”

It’s difficult to top The Ten Commandments.

“Proclaim liberty throughout all the land, unto all the inhabitants thereof”

God, I love that book (and movie.)

“He would be there all night, and he would be there when Jem waked up in the morning.”

Oh, and another:

So we beat on, boats against the current, borne back ceaselessly into the past.

Great line from a great movie, but not the last line:

“Say, friend, you got any more of that good sarsaparilla?”

For my contribution, here are the last few lines from my favorite movie. Bonus points to those who can identify it without googling.

“How do you know they’ll print it? You can take a walk, but how far if they don’t print it?”
“They’ll print it.”
“How do you know?”

I’m sorry for all your last line book suggestions, but besides the Great Gatsby line, there’s a line that tops all of the rest.

“He loved Big Brother.”

“Are you still here? It’s over. Go home - Go!” - Ferris Bueller’s Day Off

In another movie, can’t remember which one, the last line of the credits says “If you’d left when the credits started, you’d be home by now.”

I think that was Spaceballs. Or was that another John Hughes film?

I came in to add Hamlet’s “The rest is silence” as he dies, but I see you are asking for the very last line.

So I’ll add Gone With the Wind: “After all, tomorrow is another day.”

Three Days of the Condor.
Roddy

Three Days of the Condor. Not difficult.

Curse you Roddy!!! You are the patron demon of simulposts!!!

My favorite last line in literature is from Cyrano de Bergerac, because it has so much emotional resonance with the content and meaning of the play. It’s too much to try to put into a post; read the play, or see it, and you will know why. It still makes me tear up just thinking about it.

Cyrano: My white plume! (looks up at Roxane, and dies.)
Roddy

Sheer dumb luck on my part, I assure you. And the first time for me. Anyway, I couldn’t believe it went over two hours without anyone answering it.

Roddy

Another good King ending:

“…Darling.”

A couple from Harlan Ellison:

And, a little more obscure, but it never fails to chill me:

Awesome story. One of my favs. Nightmarish in every way.

“Tomorrow is another day”

The horror … The horror!

“Forget it, Jake - it’s Chinatown.”

For the Snark was a Boojum, you see.
