"I'm happy that he's getting married, this kind of wandering guy, who, you know, has been in and out of relationships ever since he split with his wife Marcia. I have never seen him so happy. I know he's got a lot of money now, but even beyond that, he's a happy person," producer Sid Ganis told the Hollywood Reporter.

Lucas married the DreamWorks Animation chairman at Skywalker Ranch in Marin County on Saturday, June 22. A spokesperson for the director said that Lucas' son Jett served as the best man while his daughters Amanda and Katie served as bridesmaids. The wedding was officiated by Bill Moyers.
