The Houses of Doom Collection

Four Italian horror movies from filmmakers Lucio Fulci and Umberto Lenzi - "The House of Clocks", "The Sweet House of Horrors", "The House of Lost Souls", and "The House of Witchcraft" - all with a haunted house theme. Originally they were intended to be a TV series (Houses of Doom), but were deemed too gory for television and were shelved until an eventual later release.
