I read recently that a neighbor of Orson Welles once advertised his home for sale. Part of the ad read: "Have Orson Welles as a neighbor!" Mr. Welles was not amused. For nearly a decade, Zillow has been conducting an annual Celebrity Neighbor Survey, in which members of the public are asked which celebrities they would most like to have as a neighbor, and which celebrities they think would make terrible neighbors. The results of the 2014 survey are in.
