You could call it a bit of a Jedi mind trick: Earlier this year, George Lucas was able to fire the director and C.E.O. of his long-delayed and ill-defined Los Angeles museum project without causing much of a ripple. Although, on some level, this latest setback was hardly a surprise development for the legendary filmmaker’s decade-plus, $1.5 billion, self-funded boondoggle. After more than five years and three delayed openings, Sandra Jackson-Dumont was quietly thanked for her service and replaced by an interim C.E.O.—former Paramount Pictures and 20th Century Fox C.E.O. Jim Gianopulos, of all people—to oversee the completion of the building. But establishing the curatorial vision for the Lucas Museum of Narrative Art will fall to Lucas himself.
