The Wizard of Oz (1939)
Billie Burke: Glinda
Glinda : You have no power here! Begone, before somebody drops a house on you, too!
Glinda : Only bad witches are ugly.
Dorothy : Oh will you help me? Can you help me?
Glinda : You don't need to be helped any longer. You've always had the power to go back to Kansas.
Dorothy : I have?
The Scarecrow : Then why didn't you tell her before?
Glinda : Because she wouldn't have believed me. She had to learn it for herself.
The Tin Man : What have you learned, Dorothy?
Dorothy : Well, I, I think that it, that it wasn't enough just to want to see Uncle Henry and Auntie Em. And it's that if I ever go looking for my heart's desire again, I won't look any further than my own backyard. Because if it isn't there, I never really lost it to begin with. Is that right?
Glinda : That's all it is.
Glinda : Pooh, what a smell of sulfur.
