Edward Doheny — the oilman at the center of the Teapot Dome scandal — spent about $3 million building this 55-room Tudor Revival for his son Ned in 1928. Ned and his secretary Hugh Plunkett were found shot dead in a guest wing. The official finding was murder-suicide. The family stayed until 1955. The city bought the estate in 1965, and the house has since played the mansion in There Will Be Blood, The Big Lebowski, Spider-Man and dozens more.
