Director George Lucas’ Skywalker Ranch is so impressive that it has its own Wikipedia page. The home isn’t just for living—it’s also a workplace and a film location. The Marin County property is 4,700 acres, and Lucas, a billionaire, spent $100 million renovating the property.

The Marin County estate has a 300-seat theater, two-story library, underground parking for 200 cars, a garden, vineyards, and it’s own fire station. Lucas is secretive about his mind-blowing mansion, and visitors must be specifically invited. Pictures are not allowed. Reportedly, former president Ronald Reagan asked to visit and was turned down, not for political reasons, but because the Star Wars director was busy working on something secretive.
