I think my favorite quotes are as follows:

No, you're not listening! Or have you forgotten who really defeated the White Witch, Peter?
-Lucy, at the Stone Table, PC

I love the oh-so-subtle reminder of who is the real victor in our lives.

That's alright. Some little children just don't know when to stop pretending.
-Lucy, near the Wardrobe, LWW

Just because I adore little Lucy, and she's so darn cute when she flings her brother's words back at him.

For Narnia! And for Aslan!
-Peter, Battle of Beruna, LWW

Come on; who didn't get chills down their spine as you sat in the dark theater and heard Peter yell this from atop his white unicorn?

"We have nothing if not belief." - Reepicheep, VotDT

"You doubt your value. Don't run from who you are." - Aslan, VotDT

Professor Kirke: "You seem to have upset the delicate internal balance of my housekeeper."
Peter: "We're very sorry, sir, it won't happen again."
Susan: "It's our sister, sir. Lucy."
Professor Kirke: "The weeping girl?"
Susan: "Yes, sir. She's upset."
Professor Kirke: "Hence the weeping."
- LWW

Susan: "She thinks she's found a magical land... In the upstairs wardrobe."
Professor Kirke: "What did you say?"
Peter: "Um, the wardrobe. Upstairs. Lucy thinks she's found a forest inside."
Susan: "She won't stop going on about it."
Professor Kirke: "What was it like?"
Susan: "Like talking to a lunatic."
Professor Kirke: "No, no, no. Not her, the forest!"
Susan: "You're not saying you believe her?"
Professor Kirke: "You don't?"
Susan: "But, of course not. I mean, logically it's impossible."
Professor Kirke: "What do they teach in schools these days?"
- LWW

Professor Kirke: "You seem to have upset the delicate internal balance of my housekeeper."

Oooh. XD I love that line, Libby, and quote it whenever I get the chance. I also say "Hence the X" in reference to his line, too. Professor Kirke is such a great character.

I love the quote "This is an awfully big wardrobe" when Lucy first enters Narnia. It really sums up the awe and wonder she has and the audience gets to experience. It seemed very in character. She wasn't scared or freaked out. She wanted to explore it and find out more. It was a good way for her to acknowledge that something strange had happened without her seeming too scared or naive about the situation.

Fox: Forgive me, your Majesty.
Jadis: Oh, don't waste my time with flattery.
Fox: Not to seem rude, but I wasn't actually talking to you.
[looks at Edmund]

That's my favorite from LWW. It's the moment when Edmund first sees that he may be treated like the King he is meant to be, by loyal subjects, not like the false promises that the Witch gave him.

And I love how the Fox defies the Witch in that moment

Great job of summarizing that quote, Lilygloves. It would've been easy to push far too much dialogue into that scene, but instead we got a lovely, succinct, and wholly in-character reaction.

A favorite line of mine that lover of narnia brought up in the "What you like about VDT" topic is Eustace's at the end of VDT:

"When my cousins left, at the end of the war, I missed them. As I know all Narnians will miss them, till the end of time"

(forgive me if I muffed it!) It strikes just the right tone of melancholy closure without being melodramatic or cheesy. It feels authentic, like something C.S. Lewis would have written.

Edmund's snarkiness to Miraz is up there on my list, too.

Miraz: "Tell me, Prince Edmund..."
Edmund: "King."
Miraz: "I beg your Pardon."
Edmund: "It's King Edmund, actually. Just King though. Peter's the High King. Yeah, I know, it's confusing."
- PC

Reepicheep: "Choose your last words carefully, Telmarine!"
Caspian: "You are a mouse!"
Reepicheep: "I was hoping for something a little more original."
- PC

Edmund: "You're welcome."
Peter: "I had it sorted."
Susan: "What was it this time?"
Peter: "He bumped me."
Lucy: "So you hit him?"
Peter: "No, after he bumped me they tried to make me apologize. That's when I hit him."
Susan: "Really, is it that hard to just walk away?"
Peter: "I shouldn't have to! I mean, don't you ever get tired of being treated like a kid?"
Edmund: "We are kids!"
Peter: "Well I wasn't always."

Edmund: "You're welcome."
[...]
Peter: "Well I wasn't always."

Interesting. Libby, if I may ask, why is this one of your favourite quotes? I've never thought of it as being here nor there, so I'm curious to know your reasoning.

White Witch: I could see, one day, you becoming Prince of Narnia-maybe even King.
Edmund: Really?
White witch: of course, you'd have to bring your family.
Edmund: oh.....do you mean peter would be king to?
White witch: No! no,no. But a king needs servants.
Edmund: I-I guess I could bring 'em.

WW: Tell me Edmund, are your sisters deaf?
Edmund: No.
WW: And your brother, is he... unintelligent?
Edmund: Well, I think so...

Mrs. Beaver: You should've brought a map!
Mr. Beaver: There wasn't room next to the jam!

Queen Susan: Come on Ed.
King Edmund: Just catching my breath.
Queen Susan: Well, that's all we'll catch at this rate.
Queen Lucy: What did he say again Susan?
Queen Susan: 'You girls wait at the castle, I'll get the stag myself'.

King Peter: What's this? It seems familiar.
Queen Susan: As if from a dream.
Queen Lucy: Or a dream of a dream... Spare Oom.

Professor Kirke: What were you all doing in the wardrobe?
Peter: You wouldn't believe us if we told you, sir.
Professor Kirke: Try me.

Trufflehunter: Reepicheep, stay your blade!
Reepicheep: Trufflehunter? I trust you have a very good reason for this untimely interruption!
Nikabrik: He doesn't, go ahead.

WW: Tell me Edmund, are your sisters deaf?
Edmund: No.
WW: And your brother, is he... unintelligent?
Edmund: Well, I think so, but mum says-
WW: Then how dare you come alone!

Boy Scout wrote Forgive me, your Majesty.
Jadis: Oh, don't waste my time with flattery.
Fox: Not to seem rude, but I wasn't actually talking to you.
[looks at Edmund]

Anther one of my favorites is from VDT.
Gale: When I grow up I want to be just like you.
Lucy: When you grow up you should be just like you

I love the quote "This is an awfully big wardrobe" when Lucy first enters Narnia. It really sums up the awe and wonder she has and the audience gets to experience. It seemed very in character.

Yes, that's another good one! It's one that's very close to the book, which has her think, "This must be a simply enormous wardrobe!"
Her discovery of Narnia is a great scene, perhaps my favorite.

Trufflehunter: Reepicheep, stay your blade!
Reepicheep: Trufflehunter? I trust you have a very good reason for this untimely interruption!
Nikabrik: He doesn't, go ahead.

Oh goodness, I forgot about that line. XD It's not laugh out loud humor, perhaps (...unless it's a viewing party with all my siblings, in which case nearly everything is funny ), but I can't help but to smirk a bit.
