The Human Monster [aka Dark Eyes Of London] (1939)

The first thing I should say about The Human Monster is that it was the first film to receive a 'H' certificate for Horror in England. Up till then they were all rated 'O' for 'Orror. By the way, The Human Monster is the American title. The original title is The Dark Eyes Of London from the Edgar Wallace novel of the same name. But we'll get back to Edgar later. It was directed by Walter Summers who had suffered the indignity of having his films afflicted with American re-titles throughout his career. His last film, At The Villa Rose, became House Of Mystery in the colonies, whilst Traitor Spy transformed into The Torso Murder Mystery, and McGlusky The Sea Rover became Hell's Cargo.
