The Demon Doctor / Varan the Unbelievable

That tagline .."He lures lovely women for monstrous experiments" seems a hard ask from a Doctor blessed with a face only his Mother could love. The key to his success is to strike at the dead of night as the nightclub patrons he seeks to pray on are either drunk or fail to notice his features in the dark. If this seems an unlikely film then the pairing is completed with "Varan the Unbelievable". Both films were made in 1962 one with an "X" and one with an "A" certificate.
