15 Doctors Crazier Than Hannibal Lecter
3. Dr Humpp - The Curious Dr Humpp
Dr Humpp is a surgeon living in Brazil who, for reasons unexplained, owns a talking brain in a jar. When the brain tells him it wants to control the world through sex, the doc builds a monster to go out and kidnap nubile young couples.
Even though it moves stiffly and looks like an actor in a rubber mask, the monster has no problem providing his master with test subjects. After watching the couples make love, the doc drains fluid from their bodies and injects it into himself, using it to forestall his transformation into a monster.
Or was he using it for an eternal life serum? Strangely enough, this 1969 oddity is more interested in soft-core sex scenes than narrative coherence.
