As I write this I am watching WAR OF THE COLOSSAL BEAST, something I have in the collection along with THE AMAZING COLOSSAL MAN. The viewer can't help feel for poor Colonel Glen Manning, who was trying to save a person in a crashed aircraft when he was subjected to an experimental plutonium blast. Talk about bad luck! Then bazookas blew him off Boulder Dam - what's the chance of that? And the glorious dialogue:
"We can't leave him exposed to the weather, even if he is a giant!" as well as "I'm afraid that the world doesn't think of a 60 foot man the way a sister does." Truly dialogue you'll find nowhere else. Incisive use of stock footage - this picture can't be missed. Really - a tragedy of mammoth proportions.
