Continuity mistake: At the detective agency, while Bud and Lou are talking to the murderer, the description of the murderer comes over the police radio, and it states "5 feet 11 inches, weighs 165, blue eyes, brown hair, last seen wearing a felt hat and dark borwn overcoat". Then 15 seconds later Bud says out loud, writing on a piece of paper the description "5 feet 10 inches, weight 165, blue eyes, sandy hair".
Continuity mistake: When Bud and Lou arrive at Tommy's house for the first time, and the moth makes a spooky shadow on the flashlight, the size, shape, motion, and wing motion of the shadow on the wall are different from those of the actual moth on the flashlight.
Continuity mistake: In the woods scene, when Lou says that he saw, "An empty woods full of Tommy Nelson," and Bud replies, "Don't give me that invisible stuff again," the position of Lou's right hand changes between shots.
