Besides the fame and wealth it gained as the world center of the movie industry, every dimension of the Los Angeles showed dramatic growth in the 1920s. Producing one-fifth of all the oil in the world, Los Angeles became a major center for financing, refining, and for tool construction for the oil industry. The port was second only to New York City in exports, shipping not only oranges and oil but also the myriad products of the city's manufacturing base, which had expanded to included automobiles, tires, steel, and the new aircraft industry. In 1928, Christine Collins' son, Walter, disappeared from the city and was never found, causing much bad publicity for Los Angeles Police Department who was corrupt and brutal then during Prohibition. This event was the plot of Clint Eastwood's 2008 production and direction ''Changeling'', starring Angelina Jolie as Christine and John Malkovich, based on the Wineville Chicken Coop Murders of 1928.
