A small-time magician is swept away to an enchanted land and is forced into a power struggle between three witches.

Oz: You can have a nice pile of bananas!
Finley: Oh, I see, because I'm a monkey I must love bananas!
Oz: You don't love bananas?
Finley: Of course I love bananas, I'm a monkey! Don't be ridiculous!
Glinda: [as the bubbles are flying towards the shield] The shield allows a good-hearted person to pass.
Oz: [Panicking] I'm gonna die!
China Girl: What's going on?
Finley: I'm not sure, I sneezed the plan away.
Oz: Am I dreaming?
Theodora: You're in Oz.
Oz: Oz? But that's my name. Oscar Zoroaster Phadrig Isaac Norman Henkle Emmanuel Ambroise Diggs.
Glinda: For the record, I knew you had it in you all along.
Oz: Greatness?
Glinda: No. Better than that. Goodness.
Oz: I'm afraid I can't give you what I know you want most of all. All I can offer you is this: us. I know it's not the family that you had in mind, but...
China Girl: It's perfect. Thank you, Oz.
[Oz has realized that he can pass off his stage magic as the real thing to defeat Evanora and Theodora]
Oz: Look, I know I'm not the wizard that you expected. But I might just be the wizard that you need.
Glinda: You said you were just a con man.
Oz: Precisely!
Glinda: Nothing but a trickster?
Oz: Yes!
Glinda: A terrible cheat!
Oz: The best there is.
Glinda: A carnival magician's going to put on a show.
Oz: I'll put on the show of a lifetime! The likes of which the land of Oz has never seen! Magic! Mystery! Prestidigitation! It'll be my greatest trick yet.
China Girl: Why don't you just use this?
Finley: It's got a knife.
Glinda: If it was easy we wouldn't need a wizard, would we?
Oz: I'm your wizard.
[big smile and a wink]
Glinda: Well done, Tinker, your machine works beautifully!
Master Tinker: That's just workmanship. What you displayed was true courage.

Oz: [to Theodora] Where's your broom?
Theodora: You don't know much about witches, do you?
China Girl: Great. Let's go kill ourselves a witch!
Theodora: There's so much good here, it sickens me.
Glinda: [facing execution] The dreams of the people live on.
Oz: [sucked into a tornado] Please, I don't want to die! I haven't accomplished anything yet!
Evanora: What's the matter, Glinda, out of bubbles?
Glinda: I don't need them, bubbles are just for show!
[from trailer]
Finley: Did those crows just say we're gonna die?
Glinda: A con man couldn't have done all this. You're much more than that.
Oz: Well then, it looks like I've got you fooled, too.
Glinda: The only person you've got fooled is yourself.
Oz: [whispers to Glinda] I might not actually be a wizard...
Glinda: Yes, but they don't know that.
Glinda: What they lack in stamina the Tinkers make up for in ingenuity. The can build anything.
[Tinkers all cheer]
Elder Tinker: And I tell ya what else. We can build anything!
Oz: Frank, the sock is on the door!... Knock!
Oz: You stood by me when other monkeys would have flown away.
Oz: I don't want to be a good man... I want to be a great one.
[Evanora tries to flee]
Glinda: Not so fast! You and I aren't finished here.
Evanora: You have the throne, Glinda. What more could you want?
Glinda: You can't give me that. You took what mattered most from me: my father.
[from trailer]
Oz: How hard can it be to kill a Wicked Witch?
Oz: Theodora, I know your wickedness is not your doing! And should you ever find the goodness within you, you are welcome to return!
Theodora: NEVER!

Oz: Now, it's time for gifts!
[Knuck starts blowing his trumpet]
Master Tinker: Knuck, not now!
