Alternate Endings

I ran across this wonderful essay about endings, twist endings, and alternate endings. It contains spoilers for The Sixth Sense and Casablanca, and you do not want to spoil those movies for yourself if by some miracle you do not already know how they end. But if you have, check out this article. I would actually recommend skipping down to the spoiler warning and read from that point, unless you're interested in talk about dinner theater.
