Superstition (1982) was filmed at Garbutt House in Los Angeles.
Wikipedia tells an interesting story of the filming at this location:
"In 1981, a low-budget Carolco horror film called "Superstition" (about a haunted house on the site where a woman was put to death as a witch 300 years earlier) was shot at Garbutt House. The shooting of "Superstition" was reportedly subject to incidents of alleged "haunting", including one in which a security guard who was required to spend the night in the house quit after reporting he had seen a "ghost", another security guard who saw the helmet on a Knight's armor display float off the shoulders of the armor and disappear into the kitchen area and another in which the film's director was locked in a room when the doorknob fell off and had to be pried free with crowbars."
