After Sam has defeated the spider at the Pass of Cirith Ungol he runs to unwrap Frodo from the spider's webbing. After the wrapping is off, the camera is looking down onto Frodo and you see Frodo's full face and his BIG eyes wide open and "dead". Very much a focal/visual point. Cut to the next few seconds where the camera angle is straight on as Sam is about to pick up and cradle Frodo, Frodo's eyes are very much shut only to be open again as the camera's POV moves above / behind Sam.
