Jess Franco’s The Diabolical Dr. Z (1966) is an early career masterpiece. A Woolrich-ian noir revenge tale blended with elements of horror and sci-fi (and echoes of Franju and Lang), it’s a key transitional work in Franco’s filmography, with connections to his past films and premonitions of what’s yet to come. For those new to Franco, this is a highly recommended place to start.
The film begins as murderer Hans Bergen (Guy Mairesse) makes a daring escape from prison, only to collapse at gate of Dr. Zimmer (Antonio Jiménez Escribano). Bergen is taken to Zimmer’s laboratory, where robotic, spider-like arms clamp around his body and hold him in place while his body is prodded for experiment. Next, Dr. Zimmer and his daughter, Irma (Mabel Karr), interrupt the International Neurological Congress, where Dr. Zimmer reveals that he has continued controversial work begun by Dr. Orloff, and has discovered that the brain and spinal column control impulses towards good and evil, and that morality is part of our nervous system and not psychological. Zimmer has made a “Z-ray which can neutralize or stimulate these zones.” When he asks for permission to test on human subjects, the congress—lead by doctors Vicas, Moroni and Kallman—scorn Zimmer, who immediately dies of a heart attack. His daughter vows to carry on with the work.
