Miracle on 34th Street is an iconic Christmas film starring Maureen O'Hara as Doris Walker and and Natalie Wood as her daughter Susan. The story revolves around a no-nonsense single mother who raises Susan not to believe in fairy tales like Santa Claus.
While much revolves around the life of Kris Kringle and the sales department at a New York City Macy's store, the film's denouement is really a courtroom drama. Doris's neighbor, Fred Gailey (played by John Payne), is an attorney who befriends Kris. When Kris faces legal action declaring him to be insane, Fred quits his job at a law firm and represents Kris in court. In the end, Fred's clever presentation of the evidence (including a display of many mailbags of letters addressed to "Santa Claus") and disarming personality help secure a dismissal.
