George Lucas
Price: $28 million*
Location: Marin County, CA
Skywalker Ranch, directed by George Lucas, is so magnificent that it gets its own Wikipedia page. The house isn’t simply a place to live; it’s also a place to work and a film set. Lucas, a billionaire, spent $100 million restoring the 4,700-acre Marin County property. The 300-seat theater, two-story library, subterranean parking for 200 automobiles, garden, vineyards, and its own fire station are all part of the Marin County estate. Lucas keeps his mind-blowing mansion a secret, and guests must be expressly invited. Photographs are not permitted. Former President Ronald Reagan reportedly requested a visit but was turned down, not for political reasons, but because the Star Wars director was working on something secret.
