El secreto del Dr. Orloff

In THE MISTRESSES OF DR. JEKYLL (aka: DR. ORLOFF'S MONSTER), the demented title character kills, then turns his cheating wife's lover into a remote control zombie robot. He then sends his new zombot out to slaughter various ladies of the night.

Enter the Doctor's niece, who arrives for a visit. Unbeknownst to her, it's her dad that's now a reanimated murderer!

Director Jesus Franco has really made a great horror film here. It's dark and bizarre, and the method used to facilitate the killings is ingenious! There's a macabre atmosphere and many genuinely creepy moments. The finale is also quite satisfying...
