This is about the worst movie I have ever seen--terrible acting..terrible special effects and bad camera work. I kept expecting the robots from Mystery Science Theatre 3000 so pop up. This movie was made for them to make fun of. When there was an earthquake someone just stood and shook the camera and the actors fell back and forth against the walls. I thought this was made in the 70s the sets were so bad and the special effects were a joke. Their computer screen at the military base or whatever it was looked like the original pong game. The dialogue was hilareous it was so stupid. DONT RENT IT AND DONT BUY IT>
