Dance of the Dwarfs

Peter Fonda was hospitalized twice during the shoot, once with an infected finger and then with a foot injury from a Helicopter landing on it. Deborah Raffin was hospitalized with pneumonia, closing down shooting for five days. Director of Photography Michael Butler contracted dysentery and had to be fed intravenously.

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.

Midway through the credit roll, a listing for 'Chaquita The Wonder Chicken' is included, amongst the other small role characters.
