I’m willing to let him off for his transgressions! Hammer Films had a busy year in 1966, releasing six movies, so it's no shock that the standard of those films wasn't consistently high. *Rasputin the Mad Monk* was shot right after *Dracula Prince of Darkness*, but despite receiving an "X" rating from the BBFC, it’s rather mild and functions more as a historical drama than a horror movie. Really, Christopher Lee’s performance as the central figure is what prevents this film from being totally awful, even though he wears a very noticeable and silly beard. The story itself—and it's quite imaginative—presents Rasputin as a hard-drinking, womanizing brute with an interest in hypnotism, which he uses to achieve his goals. The visuals are vibrant, and Lee is the center of attention as various men and women appear and disappear, all leading up to a climactic sequence characteristic of Hammer Films. However, the sluggish tempo, flimsy narrative, and the sense that it was thrown together quickly prevent this from being anything more than a way to pass some time at Hammer Studios. It gets a 6/10 from me.
