Changeling is an upcoming American period thriller set for release in 2008. The film is set in the 1920s and is loosely based upon the real-life Wineville Chicken Murders. It tells of a woman who comes to suspect that the son returned to her after a kidnapping is not her own. It was directed by Clint Eastwood and written by J. Michael Straczynski. The film was produced by Imagine Entertainment and Malpaso Productions for Universal Pictures. Ron Howard was originally slated to direct, but scheduling difficulties and Universal's desire to fast track the project led to his replacement by Eastwood.
