 Chaney's role in "The Haunted Palace" was originally meant to be played by Boris Karloff, but Karloff had contracted an illness while making "Black Sabbath" in Italy.The set for the village of Arkham was quite small, and used forced perspective to appear larger.Both the front of the palace and the underground dungeon later appeared in Corman's "The Terror", which was shot on sets from other AIP films.
