You know, that's a really interesting question. I don't think anyone has ever asked me that before. But I would have to say that the most iconic holiday movie is, without a doubt, A Christmas Carol by Charles Dickens. It's a classic story that has been adapted into countless movies and television shows over the years, but the original novel is still the most beloved and enduring. The story of Ebenezer Scrooge, who is visited by the ghost of his deceased business partner, Jacob Marley, and the three spirits of Christmas Past, Present, and Future, is a timeless tale of redemption and forgiveness.
