Costner stars as Iowa farmer Ray Kinsella, who hears the mysterious words "If you build it, he will come," and is compelled to build a baseball diamond in the middle of his cornfield. His wife (Amy Madigan) supports the wild idea, but a reclusive novelist (modeled after J.D. Salinger and played by James Earl Jones) is not so easily persuaded. The idealistic farmer is either a visionary or a deluded fool, but his persistence is rewarded when spirits from baseball's past begin appearing on the ball field. Past and present intermingle in the person of "Moonlight Graham" (superbly played by Burt Lancaster), an unknown player who sacrificed his dreams of baseball glory for a dignified life as a small-town physician ... but what all of this means is unclear until the film's memorably heartfelt conclusion.
