Temperature troubles

To ensure the movie felt and looked as authentic as possible, 'Predator' was nearly entirely filmed in a Mexican jungle close to Puerto Vallarta.

However, shooting on location certainly had its drawbacks, as the cast had to battle against the sweltering heat and oppressively stuffy conditions.

Bill Duke - who played Mac - recounted: "We're talking about hot heat — and humid heat. We're not talking about 80 degrees. We're talking about 90-something or more. We're talking about having to wear this gear that is heavy itself, and then the guns and stuff, and mine was like a gun off a battleship machine gun. So you're carrying your bodyweight, you have clothing on, and then you're crawling through the jungle on your stomach and there are coral snakes and spiders and scorpions and a lot of different things."
