Rain Man is a 1988 American road comedy-drama film directed by Barry Levinson and written by Barry Morrow and Ronald Bass. It tells the story of abrasive and selfish wheeler-dealer Charlie Babbitt, who discovers that his estranged father has died and bequeathed his multimillion-dollar estate to his other son, Raymond, an autistic savant whose existence Charlie was unaware of. Morrow created the character of Raymond after meeting real-life savant Kim Peek; his characterization was based on both Peek and Bill Sackter, a good friend of Morrow who was the subject of Bill, an earlier film that Morrow wrote.
