This is one movie that’s appropriate to show any time between Thanksgiving and Christmas, because that’s when it takes place. The setting: New York City. The plot: a department-store Santa, played by Edmund Gwenn, claims to be the real deal – and a young girl, played in this 1947 holiday film by a sweet and tiny Natalie Wood, believes him. Maureen O’Hara and John Payne co-star. The store, by the way, is Macy’s, and this movie, over the decades, has generated more free publicity, and good will, for the store and its annual Thanksgiving parade and Christmas festivities that there’s probably no real way to calculate it.
