Miracle on 34th Street (1947)
Natalie Wood: Susan Walker
Susan : I believe... I believe... It's silly, but I believe.
Susan Walker : If you're really Santa Claus, you can get it for me. And if you can't, you're only a nice man with a white beard like mother says.
Susan Walker : There's no such thing as giants.
Fred Gailey : What about the one Jack killed?
Susan Walker : Jack? Jack who?
Fred Gailey : Jack from "Jack and the Beanstalk".
Susan Walker : I never heard of that.
Fred Gailey : Sure you have. You must have forgotten. It's a fairy tale.
Susan Walker : Oh... one of those. I don't know any of those. My mother thinks they're silly.
