Witchfinder General (1968),
directed by Michael Reeves.
Truly a great movie, because of a deep look into the worst of the human condition (also narrow-mindedness). It manages to disturb and induce a general feeling of horror due to its violence.
The final movie of Michael Reeves who sadly died of a drug overdose shortly after the film was released. I must say, the "Witchfinder General" is well-made though it's low-budget. Vincent Price as a horror maestro of course doesn't disappoint. As a titular hero he delivers us a vicious and brilliant performance.
Certainly worth seeing!
