"Night Monster is a neat little B thriller in the "old dark house" tradition with some memorable twists and a very competent cast. Although Bela Lugosi is top-billed, he's completely wasted as the head butler who has little more to do than knit his brows, roll his eyes, and occasionally stare malevolently... Although it drags in places, Night Monster is a very effective and very dark B programmer. Charles Van Enger's superb cinematography and Ford Beebe's assured direction enhance some very chilling moments. Dr. Timmon's demise is particularly notable - as he cowers in a darkened corner of his massive bedroom, a menacing shadow first covers half of his quivering form, then envelops him completely as the thing casting the shadow runs full speed at him. No less a film titan than Alfred Hitchcock is said to have admired Night Monster." - Brian Schuck, Films From Beyond the Time Barrier
