About 5:15 into the movie, after Master Pain burns down Chosen One's house, baby Chosen One goes rolling down a hill. If you look closely, you'll see his shoe fly off at 5:26. Well, in the next shot, his shoe is back on! Isn't that amazing?

(Also, if you keep watching, the same piece of footage gets looped, because you'll see his shoe fly off again! How did Chosen One wind of with both of his baby shoes if one flew off when he was rolling down the hill (twice)?
