This is a stunning work of artistic genius and one of the finest “Englische neo-Realismus” films of the Fifties. Director Quentin Lawrence plumbs the depths of eldritch horror with his groundbreaking, never-bettered use of stock footage and back projection. Star-for-hire Forrest (sic) Tucker excels in his portrayal of Mensch on the brink of interplanetary miscegenation. Your mother really won’t like this one, dear.
