this film have a lot of strong point . it have one of the best horror cast outside of the lugosi karloff chaney circle represent lionel atwill and fay wray and and dwight frye and plus lead man melvyn douglas . it get all the right ingredient represent bat and a castle with lot of stone staircase and a mad scientist and townspeople waving torch and hunt vampire and an igor type character and a beautiful girl and even a goofy haired burgomeister . the soft focus camera work be moody and imaginative . there even some good comic relief nicely space throughout the script . but it not really a monster movie because there be nothing supernatural go on in kleinschloss ( little castle ) . the plot revolve around the generic crazy scientist ( nicely play by atwill ) who value his work more highly than human life . it not top tier material and because of a ho hum resolution of the plot and some embarrassingly bad dialog for dwight frye . but it worth a look if you like early b or w horror picture .
