Continuity mistake: As Gal is in front of his pool, standing with his back to the rock face, an immense boulder is tumbling straight towards him. It comes down the mountain to his right. As it gets airborne it is still to his right. Camera cuts facing his right and it is shooting past his right side, still moving straight downward. All good. But as the camera cuts to the front of Gal, the boulder smashes into the pool a couple yards to the left side of Gal. (00:04:50)
Factual error: The team are shown using bare, wet hands to drill through and handle rough, steel reinforced concrete. Without gloves on, the skin on their hands would have been shredded and bleeding in a very short time.
