The Keeper on AllMovie

This macabre horror satire from Canada features an arch performance from Christopher Lee as the sinister overseer of the Underwood Asylum, whose charges come from extremely wealthy families. When relatives of these patients begin to turn up dead in alarming numbers -- with their incarcerated heirs' fortunes subsequently signed over to the asylum -- hulking twin patients the Biggs Brothers (Jack Leavy and Leo Leavy) hire intrepid detective Dick Driver (Tell Schreiber) to uncover Lee's connection to the crimes. It turns out The Keeper maintains complete control over the inmates by means of a powerful and sinister-looking hypnosis device, directing them to do his murderous bidding and doling out remote-controlled punishments to those who step out of line. A bit too jokey to be suspenseful, this film still has its inventive moments, and plays like a slight parody of Norbert Jacques's Dr. Mabuse series.
