Lucas and Hobson were married on June 22 at Skywalker Ranch, in Marin County, California. Journalist Bill Moyers officiated the ceremony, and director Steven Spielberg toasted the groom.
In addition to serving as president of Ariel Investments, Hobson, 44, is chairman of Dreamworks Animation and a financial contributor with CBS.
Lucas, 69, sold his production company, Lucasfilm Ltd., to the Walt Disney Company for $4.05 billion in October 2012. "Star Trek" director J.J. Abrams has since signed on to direct the first in a series of planned "Star Wars" sequels, set to begin filming early next year.
