In the Russian countryside, Rasputin heals the sick wife of an innkeeper. When he is later hauled before an Orthodoxbishop for his sexual immorality and violence, the innkeeper springs to the monk's defence. Rasputin protests that he is sexually immoral because he likes to give God "sins worth forgiving". He also claims to have healing powers in his hands, and is unperturbed by the bishop's accusation that his power comes from Satan. Rasputin heads for Saint Petersburg, where he forces his way into the home of Dr Zargo, from where he begins his campaign to gain influence over the Tsarina. He manipulates one of the Tsarina's ladies-in-waiting, Sonia, whom he uses to satisfy his voracious sexual appetite and gain access to the Tsarina. He places her in a trance and commands her to cause an apparent accident that will injure the czar's young heir Alexei, so that Rasputin can be called to court to heal him. After this success, he hypnotizes the Tsarina to replace her existing doctor with Zargo. However, Rasputin's ruthless pursuit of wealth and prestige, and increasing control over the royal household, attracts opposition. Sonia's brother, Peter, enraged by Rasputin's seduction of his sister, enlists the help of Ivan to bring about the monk's downfall. Peter, in challenging the monk, is horribly scarred by acid thrown in his face, and suffers a lingering death. Tricking Rasputin into thinking his sister Vanessa is interested in him, Ivan arranges a supposed meeting. However, Zargo has poisoned the wine and chocolates, which the Monk starts to consume. Soon Rasputin collapses, but the poison is not enough to kill him. In the ensuing struggle between the three men, Zargo is stabbed by Rasputin and quickly dies. Ivan manages to throw Rasputin out of the window to his death.
Rasputin the Mad Monk was filmed back-to-back in 1965 with , using the same sets at Hammer's Bray Studios. Lee, Matthews, Shelley and Farmer appeared in both films. In some markets, it was released on a double feature with The Reptile. It was the third collaboration between Christopher Lee and Don Sharp, following The Devil Ship Pirates and The Face of Fu Manchu. Lee later said, "The only way you can present him is the way he was historically described. He was a lecher and a drunk, and definitely had healing powers. So he was a saint and a siimer... There were very few good sides to him. Rasputin is one of the best things I’ve done. " "I think it's the best thing Chris Lee's ever done," said Sharp in 1992. "Rasputin was supposed to have had this ability to hypnotise people, well Chris practically developed that ability." Filming started 8 June. Don Sharp says the budget was cut during filming, causing the loss of several key scenes. He also claims Yusopov's lawyers threatened Hammer shortly before filming was to commence, necessitating last minute rewriting of the script. A scene of Sonia's suicide was filmed but not shown. The original ending had the lifeless Rasputin lying on the ice with his hands held up to his forehead in benediction. However, it was considered controversial for religious reasons, and was removed. Stills of the original ending still exist. Sharp says the final fight scene between Francis Matthews and Christopher Lee was greatly cut by Tony Keys when Sharp had to leave the film during editing. Sharp had greatly enjoyed the experience of making his first two Hammer films - Kiss of the Vampire and Devil Ship Pirates - but not Rasputin. As a child in the 1920s, Lee had actually met Rasputin's killer, Felix Yusupov. In later life Lee met Rasputin's daughter Maria. A novelization of the film was written by John Burke as part of his 1967 book The Second Hammer Horror Film Omnibus.
