How does Ana lose her luck? She isn't touched like the winner in the casino. She doesn't sell her luck like the captives. Federico just steals her photo. She doesn't even know about it. Doesn't that have extensive implications? If people can just get lucky by taking, or stealing, photos of other people who know nothing about it, what's the point of it all? No need to run through forests or have creepy insects on your head (incidentally, is Tomas cheating by having molasses on his hair?). No need for Russian roulette. All you need is a camera. It also suggests we could all be having our luck stolen, which is kind of silly - we don't believe it so we don't believe the film. Pity, because I did actually enjoy the movie.
