One of the most recognisable faces in horror, Boris Karloff (or simply KARLOFF', as he was often billed) has been described as "to the horror movie what Fred Astaire was to the musical". The Man They Could Not Hang, The Man With Nine Lives, Before I Hang, and The Devil Commands form the "Mad Doctor" cycle, a thematically linked series of films where Karloff always plays a doctor whose obsessions inevitably lead them to murder!
