We've included some of America's most-watched Christmas movies (Home Alone, A Christmas Story, Elf) of course, but you'll also discover Christmas romances (The Holiday, Last Christmas), animated picks for the kids (Arthur Christmas, A Charlie Brown Christmas), raunchy adults-only Christmas comedies (Bad Santa, The Night Before), nostalgic '40s-era films (The Shop Around the Corner, It Happened on Fifth Avenue) and even holiday horror movies and action flicks (Black Christmas, Die Hard).
