So many movies take the NYPD to task for corruption, but it seems like fewer put the spotlight on the LAPD. Clint Eastwood's new film, Changeling, follows the true story of Christine Collins and her missing son, Walter. When the LAPD offers up a kid who isn't her son and refuses to cop to it, scandal ensues. Could be the next great thing from Clint and Angelina Jolie. Watch the trailer after the jump.
