The human remains at the bottom of the vast sea, floating as if they were alive. If it were a shipwreck or something else. They were put there and origin is unknown. The pictures taken were too dark and it saw nothing. So if it's not alive it doesn't glow in the darkness of night. Not for a picture, use of a waterproof flash. For sure you can see them with the eyes and the daylight barely reaching the bottom of the waters, it was still too dark.
Maybe they were super famous exactly as they are because of that one movie. On the silver screen and very alive.
