This Corman's flick + Tomb Of Ligeia are definitely the best of all gothic horror, Edgar Allan Poe inspired series. The Haunted Palace doesn't miss on producing dark atmosphere and watching Vincent Price undergoing a possession is a nice treat. My favourite scene is meeting the mutants in the middle of village, kind of "zombie element" provided before Night Of The Living Dead was even shot. Nice piece of B-movie!
Decent entry to Corman's "Poe series". Price is absolutely in his element, and the lush sets and production design create a wonderful, gloomy gothic atmosphere. But it does succumb to the major flaw of most of these types of movies: way too many scenes of people wandering down dark hallways - it's slow-paced, but Charles Beaumont's script offers some smart dialogue. One of Ronald Stein's best scores.
