Sci-Fi Wire got to check out the "The Haunted Mansion - Hollywood" - an interactive walk-through attraction based around the Eddie Murphy movie - which, in turn, is based around an attraction. The amusement is 30,000 square feet of movie-related goodies attached to Hollywood's El Capitan theater, including:

• Several large set pieces, including the film mansion's foyer, crypt, mausoleum, library and solarium.
• A 10-minute stage show revealing secrets of the movie's visual effects.
• Exhibits of the film's costumes, production design and makeup effects.
• Places where visitors can get photographed against film backdrops, which are then compiled into a digital photo scrapbook.
• Several play areas for children, with games and projects themed to the movie.
