I vaguely remember a movie where a bunch of people were somewhere where there were possibly gorillas that came and killed some of them when they searched in the sand and found diamonds? It sort of seemed like a smaller version of the Colosseum almost. There was also another scene where one person went in a cave and the other person sat outside the cave. Then you heard noises coming from inside the cave, the person outside thought the person inside the cave was trying to freak them out, then something is thrown out of the cave, and it is the other person’s eye.
