witchfinder general (1968)

aka Edgar Allan Poe's Conqueror Worm. Matthew Hopkins: Conqueror Worm. Matthew Hopkins: Witchfinder General. The Conqueror Worm.
England 1645, during the civil war. A time for the witchfinders to exploit the superstitious villages of East Anglia. Such a man is Matthew Hopkins (Vincent Price), who tours the area dispensing justice against witches, for a price. But when Hopkins picks on a priest and his niece, he incurs the wrath of Richard Marshall (Ian Ogilvy), the girls fiance.
A fantastic premise for this horror, come historical melodrama. Which loosely uses real life events as the basis of this very dark and effective film. It also features the best performance that Vincent Price ever gave. This was reputedly because he and the director didn't get on and you can see it in the antagonistic performance.
