George Lucas

In 1978, the year after the release of "Star Wars," legendary director George Lucas began putting together what would become Skywalker Ranch. He paid an estimated $100 million for the 4,700-acre property, of which just 15 acres are developed. It isn't exactly Lucas' home residence, but it is commonly utilized as a Skywalker Sound office and a hangout for filmmakers. To maintain the estate's natural charm, the parking lots are subterranean. Lake Ewok, a working ranch, a world-renowned art collection, and a 300-seat cinema theater with the world's most advanced sound system are among the amenities.

The Ranch has a barn with animals, vineyards, a garden with fruits and vegetables used in the on-site restaurant, an outdoor swimming pool, and fitness center with racquetball courts, a man-made "Ewok Lake," a hilltop observatory, a 300-seat theater called "The Stag" as well as theater screening rooms, and parking that is mostly hidden underground to preserve the natural landscape. In 1987, Skywalker Sound relocated to the ranch and presently occupies the Technical Building. Under the stained-glass dome of the Main House is a business research library. Skywalker Ranch has its own fire station, which is part of the Marin County mutual assistance system and is frequently called upon to help Marinwood firefighters.
