Maniac
(also known as Sex Maniac) is a 1934 American black-and-white exploitation horror film directed by Dwain Esper and written by Hildagarde Stadie, Esper's wife, as a loose adaptation of the 1843 Edgar Allan Poe story "The Black Cat", with references to his "Murders in the Rue Morgue".[2] Esper and Stadie also made the 1936 exploitation film Marihuana.
The film, which was advertised with the tagline "He menaced women with his weird desires!", is in the public domain.
A restored version was made available in 1999, as part of a double feature with another Esper film, Narcotic! (1933). John Wilson, the founder of the Golden Raspberry Award, named Maniac one of the "100 Most Amusingly Bad Movies Ever Made" in his book The Official Razzie Movie Guide. Maniac has received negative reception since its release, being the first film considered the worst ever made and is an oft-cited example of pornographic films.
Plot
Don Maxwell is a former vaudeville impersonator who's working as the lab assistant to Dr. Meirschultz, a mad scientist attempting to bring the dead back to life. When Don kills Meirschultz, he attempts to hide his crime by "becoming" the doctor, taking over his work, and copying his appearance/mannerisms. In the process, he slowly goes insane.
The "doctor" treats a mental patient, Buckley, but accidentally injects him with adrenaline, which causes the man to go into violent fits. In one of these fits, Buckley kidnaps a woman, tears her clothes off, and rapes her. Buckley's wife discovers the body of the real doctor and blackmails Don for turning her husband into a zombie. The ersatz doctor turns the tables on her by manipulating the woman into fighting with his estranged wife, Alice Maxwell, a former showgirl. When the cat-breeding neighbor, Goof, sees what's going on, he calls the police, who stop the fight and, following the sound of Satan the cat, find the body of the real doctor hidden behind a brick wall.[2][3][4]
