Visible crew/equipment: During the final battle, shortly after Dutch runs by a plant that moves and catches the Predator's eye, watch as the Predator takes a few strides from rock to rock. When he jumps down off the last rock you can see a cable above his head helping him make his jump. This same cable can also be seen from a different shot about ten seconds later when Dutch runs into the Predator. (01:29:45)
Visible crew/equipment: When Arnie says 'oh s***' and falls off the cliff, watch as the camera goes over the edge. If you look on the mountain, you can see a shadow of a black ball with a cable attached: this is the camera filming the shot which has been thrown off the cliff.
Visible crew/equipment: Watch when Arnie is sliding down the cliff: it shows a shot from his eyes looking down at his feet, and you can see the wooden platform he's sliding down.
