The Best/Worst movie of all time to come on Skinemax was called "Dinosaur Island", it was so awful that it was hilarious, and of course it had obligatory boobies and hump scenes.
It was about a military plane, there was a pilot, a hard ass officer, and three prisoners who were goofballs and I think they were being taken to the stockade for going AWOL or something. Anyway the plane crashes on an island that is inhabited by dinosaurs and slutty cave women. It was a classic.
I remember there was one scene where they were walking around the island which is supposed to have no technology at all, and in the background you can see a power line and tower.
