Confession time: I saw 'Willy Wonka and the Chocolate Factory' in the theater when I was 4 ... and it scared the daylights out of me. All those horrible things happening to the kids -- especially Augustus Gloop nearly drowning in the chocolate river, then getting trapped in that tube -- haunted my dreams.

As an adult, however, I was able to watch the film again and pick up on its sly humor, particularly Gene Wilder's subtle, mischievous performance, as well as in the film's satire of the adult world as being just as greedy, grasping, and gluttonous as the world of candy-grabbing children. Nowadays, I thoroughly enjoy watching the movie, which wasn't the movie I thought it was at all.

As it turns out, the beloved cult favorite that we've enjoyed for four decades now (it just had its 40th anniversary) isn't the movie any of us thought it was. There are a lot of things people don't know about the familiar film, from its origins as a candy infomercial to its links to 'The Omen,' the 1972 Summer Olympics and the Boston subway system.

Are you ready for a list of 20 things you might now know about 'Willy Wonka and the Chocolate Factory?' As Wilder's candymaker said during Augustus Gloop's ordeal, "The suspense is terrible. I hope it'll last."
