First Appearance: Fiend Without a Face (1958)
Canadian Air Force scientists experimenting with telekinesis get things mixed up with radiation and create invisible brain monsters that strangle people. Eventually with more radiation from a near by reactor invisible brain monsters become visible then get shot. Features a really gratuitous girl in a towel scene. Great flick with a cool monster. Only available through Criterion for something like the budget for the movie. Why's Criterion always demanding insane amounts of money for cool monster flicks? I cant afford this or the Blob. stupid Criterion.
