14 Onscreen Scenes So Terrifying, They Traumatized The Actors Who Filmed Them

During filming the pool scene where Williams is surrounded by skeletons, she was utterly unaware of the fact that they were real at the time she was in the water with them. Upon finding out, Williams was completely freaked out, stating, "I think everybody got real creeped out by the idea of that." However, she explained that it wasn't so much that the skeletons were real, she was worried initially that the materials of the fake ones posed an electrical danger to herself while in the water. Yet, writer Steven Spielberg, to ease her worries, actually jumped into the pool with her, saying, "Now if a light falls in, we'll both fry."
