In 1989's "Batman", Knebworth House, a Gothic Tudor mansion north of London was used for the exterior. The interior, however, is Hatfield House, Hertfordshire. The gaming room from the movie used the long gallery, and the marble hall was used for Wayne's "arsenal" with the two-way mirror. In "Batman Returns" (1992), an original scale model was used for the exteriors of Wayne Manor. In the sequel, the passageway to the Batcave is uncovered by turning on the lights of an ornament in a nearby aquarium and dropping through a false floor in an iron maiden, although Alfred does quip that he'll "take the stairs".
