"The Rainmaker," directed by Francis Ford Coppola and released in 1997, is based on the novel of the same name by John Grisham, rather than a true story. The film follows a young lawyer who takes on a case against a powerful insurance company. While the characters and events are fictional, they reflect real themes in the legal profession and issues of justice. Grisham's work often draws inspiration from actual legal cases and the struggles of individuals against larger institutions, but this particular narrative is a product of his imagination.

Danny Glover was not credited in "The Rainmaker" because he played a minor role as a character named J. D. "Joe" Black, who appeared in a brief scene. In some films, actors in smaller or cameo roles may not receive on-screen credits, especially if their participation is limited or if the production chooses to streamline the credits. However, Glover's performance is still recognized by fans of the film, even if he wasn't officially credited.
