Patzer

In the final scene, Evelyn moves into the rear of the helicopter to get some Cracker Jacks, and is attacked by one of the reptile men (which apparently got aboard before they took off). During the attack, Harry and the large front cockpit window can be seen to one side. Also plainly visible through the glass is the entire greenery of the jungle, right outside the helicopter; even though mere seconds before it showed them flying at a high altitude for quite some time. Apparently this scene was filmed during the time the lift off scenes were shot.
