Plot hole: In 1966 when George is about to return to his machine and the atomic bombs (or whatever) go off, George just barely gets out of there before the lava from a nearby volcano cooks him alive. Two plot holes here. One is that in the short time it takes George to walk a few meters to his machine, a volcano explodes and the lava reaches him. Thats very speedy lava..especially considering there were no mountains near George's house. Secondly when the lava approaches, it is just flowing along the ground like normal. But when it reaches George, it splashes around him like a broken water tank. That lava can certainly defy gravity.
