Trivia: In the film, when Margaret O'Brien is sad because she doesn't want to move, she knocks down snowmen and cries hysterically. It is rumored that in real life Margaret was told that her dog died when it really hadn't, just so she would cry. Apparently Margaret O'Brien denies this, claiming this story is not true. She explains that though she didn't feel it was easy to cry, she was able to muster it after being told that June Allyson - her MGM rival in sobbing - could cry on cue.
Agnes Smith: Rose, what did you get me for Christmas?

Agnes Smith: I hope it's a hunting knife.
Agnes Smith: Katie, where's my cat?
Katie the Maid: I don't know... a little while ago, she got in my way and I kicked her down the cellar steps. I could hear her spine hitting on every step.
Agnes Smith: Oh, if you killed her, I'll kill you! I'll stab you to death in your sleep, then I'll tie your body to two wild horses until you're pulled apart.
Katie the Maid: Oh, won't that be terrible, now? There's your cat.
'Tootie' Smith: Here comes the invalid. I have to have two kinds of ice cream. I'm recuperating.
Mrs. Anna Smith: If I ever catch you fibbing again like you did about John Truett, I'll give you something to recuperate about.
