Rise of the Guardians2012

Pitch:
[about his nightmares] Don't be nervous, it only riles them up more. They smell fear, you know.

Bunny:
What fear? Of you? No one's been afraid of you since the Dark Ages!

Pitch:
Oh, the Dark Ages. Everyone frightened. Miserable! Such happy times for me. Oh, the power I wielded! But then the Man in the Moon chose you to replace my fear with your wonder and light, lifting their hearts and giving them hope. Meanwhile, everyone wrote me off as... just a bad dream! "Oh, there's nothing to be afraid of!" "There's no such thing as the boogeyman!" Well, that's all about to change! [Tooth's palace begins to slowly disintegrate] Oh, look. It's happening already.

Jack:
What is?

Pitch:
Children are waking up, and realizing the Tooth Fairy never came. It's such a little thing, but to a child...

Jack:
[to Tooth] What's going on?

Tooth:
(shocked) They... they don't believe in me anymore.

Pitch:
Didn't they tell you, Jack? It's great being a Guardian, but there's a catch: If enough kids stop believing, everything your friends protect - wonder, hopes and dreams, it all goes away. And, little by little, so do they. No Christmas, or Easter, or little fairies that come in the night. There will be nothing but fear, and darkness... and me. It's your turn not to be believed in.
