NICASIO (AFP).- George Lucas, the man behind the mega-successful interplanetary saga "Star Wars," may well have retired, but his spirit looms large at the famous Skywalker Ranch.

The creator of Luke, Leia, Indiana Jones and Darth Vader bought the property in 1978 with proceeds from his first blockbuster hit, "Star Wars" to realize his dream of creating a haven for filmmaking outside Hollywood, at a cost of around $100 million, according to the Wall Street Journal.

Rare visitors allowed into the huge complex -- 4,700 acres (1,900 hectares) near San Francisco -- must first weave around hills, orchards, and pastures occupied by cows and deer.

Within its boundaries, there are several screening rooms, vineyards, an underground pool and even a small inn for clients and friends.

"The ranch has its own police so do not get away from the group; they are not very flexible," warned a spokesman during a recent media visit.

Beside an artificial pond dubbed "Lake Ewok" lies the "technical" building that houses the studios of Skywalker Sound, specializing in special effect sounds for science fiction and fantasy films -- those by Lucas but also for outside clients, recently including "Guardians of the Galaxy."

Working there are several longtime collaborators of Lucas, who refer constantly to the ideas and spirit of their revered mentor.

"George always said that music is half of the movie experience," said Matthew Wood, a Skywalker Sound employee.

On the other side of the pond, the massive white, slate-roofed main house boasts a research library with 21,000 volumes as well as the former office of the owner, now 71, who hardly comes in these days.

Lucas "is retired. He got married and just had a baby," a spokesman said, referring to his daughter Everest who was born last year.

"He is working on his narrative art museum project in Chicago,"the spokesman added.

Preserving the magic
The building -- decorated with film mementos, like Indiana Jones's bullwhip, and with pieces from Lucas's art collection, including several canvasses by Norman Rockwell -- has the air of a museum.

The filmmaker sold his company and the rights to his space opera to Disney in 2012 for $4 billion, one of the biggest ever such deals.

The media empire aims now to make good on its investment.

Three new feature-length films are planned, with "Episode VII" currently filming in London, and the animated film "Star Wars: Rebels" debuting on the Disney XD channel in 46 countries in October.

In downtown San Francisco, at the Lucasfilm headquarters, Lucas's former colleagues have gone back to work expanding the Star Wars universe while preserving its appeal for millions of fans.

With "Star Wars: Rebels," pitched at children between age six and 12, Disney and Lucasfilm also hope to suck in a new generation to the world of the Jedi and "the Force."

The TV series "represents this new era" beyond Luke and Leia, said executive producer Dave Filoni in the studio offices, decorated with a collection of hundreds of posters of Lucas's films, statues of Darth Vader, spaceships and monsters.

"Star Wars: Rebels" features five fugitive rebels who live in their spaceship and who, obviously, battle the nefarious Empire.

"George always said that you cannot rely on the Star Wars lure of ships and light sabers. You need the family to work as a story," explained Filoni, wearing his ever-present black cowboy hat.

But for fans worried about the Star Wars universe post-Lucas, Filoni promised nothing big is changing.

"Disney shows great respect for the franchise. They know that we're the ones who know it best."
