Where did all those cards COME from?
Don't get me wrong, I love this little movie. However, this one plot hole is rather severe, unless I'm missing something.
When sally is first discovered with her house of cards, there must be at least 20 - 30 decks worth. Where would they have come from? Did she steal all her neighbor's cards? Did her mother sell playing-cards and thus have a huge stock in the house?
Cool scene, though.
