Old Conan and Predator movies. Heard they had a blast filming the original Predator, lots of workout competitions, etc. It also may sound dumb, but in the newest King Kong movie they made the scene where King Kong fights the T-Rex's. Every time I watch it my blood gets going......then I go outside and step on a lizard.
