Witchfinder General was made in 1968 and in my view one of the best and certainly one of the most under rated British horror films. Rather more gruesome than the Hammer Horror output of the sixties it is loosely based on the real life activities of Matthew Hopkins, the soi disant Witchfinder Generall who terrorised East Anglia from 1645 to 1647.
Vincent Rice was rather old to play an accurate Hopkins (who was in his twenties during his reign of terror) but he puts in a typically fine performance. Still I wonder what the film would have looked like if Donald Pleasance had played the role as originally intended.
To tie the film in with the Roger Corman output of Edgar Allen Poe films it was called the Conqueror Worm in the United States.
