We discuss the odd notion of having a good scientist and a bad scientist under the same roof; the strange case of the missing romantic subplot; the late blooming lust of the mad scientist for the film's lovely co-star; the 'master race' desires that drive the plot and the dividing line that keeps pets alive in a horror film. We talk about director George Waggoner's work before and after this effort as well as the years long trail the story took to finally reach the screen. We also spend a lot of time heaping praise on the great Lionel Atwill's amazing performance as the crazed man seeking knowledge to keep the lower classes in their places!
