Supposedly retired filmmaker George Lucas has an extensive collection of art and film memorabilia, built up from his decades in the movie business. Lucas has spent the last two years putting together plans for a museum that would house his treasures. Today, he announced that the center, known as the Lucas Museum of Narrative Art, would be built in Chicago. San Francisco mayor Ed Lee made another attempt to lure Lucas to the city by offering him a space near the Bay Bridge, and previous mayors wrote letters to the filmmaker, but to no avail. Los Angeles also made efforts to tempt Lucas, but the Star Wars director, who lives in Chicago for some of the year, plumped for the Illinois city.
