About 19 minutes and 30 seconds into the movie, they are showing the story of a man locked in a room with no clothes, a safe, numbers on the wall, etc. Well, he's suppose to be barefoot since there's broken glass on the floor, but if you slow it down and look when the film starts to move fast forward of him running around the room getting the numbers, you'll see that he is clearly wearing shoes. I guess they thought you wouldn't see it, since it's moving so fast, but it stuck out to me like a sore thumb.
