The life story of the legendary Russian mystic Grigori Rasputin gets the highly fictionalized Hammer Films treatment with this liberal mix of horror and history that presents the mysterious sage as a demonic, otherworldly creature. Christopher Lee stars as the titular monk, who gains entrée to the world of the tsar by casting a hypnotic spell on two courtiers, Dr. Zargo (Richard Pasco) and the beautiful Sonia (Barbara Shelley). Becoming a trusted aide and confidant of the tsarina (Renee Ashershon), Rasputin threatens the national power structure. After Sonia kills herself, Zargo resolves to kill the interloper, but stabbing, poisoning, and even bullets dont seem to be able to kill the diabolical Rasputin. ~ Karl Williams, All Movie Guide
