Forbes Ranks World's Most Expensive Fictional Houses

The fellows at Forbes must be feeling a little light-headed. The magazine just came out with its first ever ranking of the most expensive houses in the world - that don't actually exist. Well, it's fun anyway. First they laid out a few ground rules: 1. "All the properties had to be primarily residences (no schools, evil lairs or Death Stars) and we excluded castles (sorry Cinderella, Dracula). 2. "In the interest of variety, we limited our selections to no more than one or two of a 'type.'" 3. "We eliminated any selections that were deemed too obscure." Other than that, the properties in question could come from everything from comic books to TV shows to movies and videogames.

The most expensive fictional house, according to Forbes, is Xanadu, the home of newspaper baron Charles Foster Kane in Citizen Kane, at $160 million. The house is modeled on Hearst Castle (above), the real life San Simeon, Calif., estate of media mogul William Randolph Hearst. In the #2 spot is Richie Rich's cartoon mansion, complete with diamond-walled swimming pool, at $135 million. Elsewhere on the list: Tony Stark's bachelor pad in Iron Man, at $50.8 million; Gone With the Wind's antebellum plantation Tara, at $17.2 million; Croft Manor from Tomb Raider, at $46.1 million; and Jay Gatsby's Long Island mansion from The Great Gatsby, $42.5 million.
