Peacock is a 2010 American psychological thriller directed by Michael Lander, written by Lander and Ryan Roy, and starring Cillian Murphy, Ellen Page and Susan Sarandon. It was editor Sally Menke's final film.
John Skillpa, a quiet bank clerk living in tiny Peacock, Nebraska, prefers to live an invisible life in order to hide his secret: He has multiple personality disorder, the implied result of childhood trauma inflicted by his abusive mother. His alter ego is a woman, Emma, who each morning does his chores and cooks him breakfast before he starts the day. One day while he is out of his house as Emma, a freight train caboose derails and crashes into John's backyard.
When his neighbors come to the scene, "Emma" enters his house, putting John's other life into the spotlight, so he is forced to tell his neighbors that Emma is his wife, married in secrecy.
