Clint Eastwood's Changeling (which may or may not be now known as The Exchange), is a riveting drama about a missing boy and the undying constancy of a mother's love. Angelina Jolie excels in a powerful performance as Christine Collins, whose nine-year-old son, Walter, disappeared in 1928. Five months later, police returned to her a boy they said was Walter; Christine alleged that the boy was not her son.
At the time, the Los Angeles police department was under considerable pressure due to the efforts of a Presbyterian minister, Reverend Gustav Briegleb (John Malcovich), to expose corruption within the police force. Captain Jones (Jeffrey Donovan), who heads up the investigation, doesn't particularly care whether the boy is or isn't Walter Collins; he has a publicity campaign to manage that's all about making himself look good, so he tries to convince Christine to accept the found boy as her son. When she fights back by going to the press, Jones has her committed to the psycho ward.
